About a windproof screen for gas burners
I suspect that low screens are designed primarily for alcohol burners, and even more so, for burners on dry alcohol, from those known to me, these are the lowest burners, I actually use it just on dry alcohol.
I have a small screen. I use for 2 burners. For a burner with a hose, high wind protection is not needed, t.to. Low burner itself. And to use BRS-3000, I dig in the ground in the summer itself, and in winter in the snow. Without wind protection in general, sadness and sadness.
Get in Woods!
About conical wind protection I have already made a small post. The design described there cannot support a pot. This time I decided to make an option with support. Something like Caldera Cone from Trail Designs. And since my pot and burner are titanium, it would be very cool to make wind protection too from titanium. To do this, I ordered tape 0 on Aliexpress 0.1x200x800 mm.
The most complete information on the designs of conical wind protection and stands is collected in the Pot Stands section. CONICAL site Zenstives.Net. In the same section there is an online program for creating a moded model of wind protection for your pot. What did I use. My pot. 800 ml from the Keith KP6014 set.2 l 0.8 l 0.4 l. I have already done an overview of this set. The final version of the paper model for my pot can be downloaded from the link.
In the model, you can change such parameters as the depth of the pot of pot, the height above the burner, the height of the burner itself. Unfortunately, you can not change the angle of inclination of the cone.
But you can lay the option of vertical separation in the model. T.e. so that it consists of two parts, and in a disassembled and twisted state was placed inside the pot.
Another cool option: Infernal insert. This is a smaller cone, which is inserted into wind protection and allows you to turn it into a pinch with burning wood gas. It turns out something like Caldera Ti-Tri from Trail Designs.
The last interesting option when creating a model and wind protection: combining two short pieces into one long constant castle connection. It may be useful if you could only get scraps.
Due to the fact that the angle of inclination of the cone cannot be changed, it was necessary to make changes to the model three times so that the detailed cone fit in a height of 200 mm width of my tape.
After everything has come up in size, we glue the paper model to the tape with tape so that it does not go, and cut out with scissors.
Holes for the air supply below. 20. For exhaust at the top. 30. I struck the lower row of holes with a clerical hole. It turned out perfectly. For the upper holes, the hole hole did not fit, did not reach the edge. I bought this type for 70 drill:
The usual drill tears the edges of the hole, it turns out ugly. Such a three.headed drill is obtained by a more even edge of the hole. But, due to the fact that the tape is too thin, normal rotation of the drill clockwise still torn the edges a little. The result is better when rotating the drill against the watch. It scratches a flat round hole, but the edge is slightly bent. Then we pass with a hammer and level the surface
I could not resist and immediately began to test. Burner. alcohol Vargo Triad. I already wrote about her too.
The bowler sat tight. The same than in the model. Cutting even appeared. In future versions by 1-2 mm, it is necessary to increase the diameter of the pot in the model, should help.
Test for boiling 0.5 liters of ten.degree water. 30 grams of alcohol in the burner. Heat was used. Due to too long heated alcohol, Malenechko boiled and Adovo burned inside. But it boiled in 6 and a half minutes. A total of the burner worked for 15 minutes. Cool!
Then I decided to try on a pot for 1.2 liters from the same Chinese set. He easily entered, even a small gap remained. In it, I boiled a liter of all the same cold water. With pre.grane was more accurate this time, the alcohol did not boil. Therefore, on the same 30 grams of alcohol, the burner worked as much as 23 minutes. And boiled water after 16. Great too.
This wind protection can also be used along with a gas burner. If you are afraid that it falls in the process, you can hook with a clerical paper behind the edge of the pot through the exhaust hole. Nothing fell off with me. In the photo, a pot of 800 ml, a known 25 gram Chinese BRS-3000T burner and a 230 gram gas cylinder.
Light windshield with your own hands
For the upcoming campaign in the tundra, I will have to take a burner. And the burner needs wind protection. Not only and not so much to protect the flame as a pot. After all, while the burner warms mainly the bottom, even the slightest breeze sticks the walls so that even in summer you can burn a double portion of gas. I like ready.made wind screens from aluminum sections, like this:
They come from different sections and different heights, suitable for me can be bought on Ali for five hundred. In general, not expensive. But I love to make,
over, anyone can make such a simple design, so why not take the evening, saving money at the same time? In addition, the weight of such a finished protection depresses me, it is 300-400 grams, depending on the size.
We are looking for suitable material. At first, aluminum tiles from the suspended ceiling Armstrong caught my eye. But aluminum there is not the thinnest, if the memory does not change, about 0.3 mm. Weighing showed the specific weight of exactly 900 g/sq.m. Hmm, apparently just such material on factory. No, it will not take off, we are looking for further.
Here my gaze falls on the ceiling. The lamps! Square built.in lamps for Armstrong, on ordinary lumenship lamps 4 x 18W. Each office has such. And they have dialogue made of toon.aluminum. Unfortunately, there was nothing to photograph their donor lamp, and it makes no sense, they all differ slightly in shape and profile of diffusers. I chose one in which the diffuser consisted of even plates, bent along only once, with a corner of that is. Weighing showed 542 g/sq.m, this is another matter!
Further instructions for manufacturing “how to draw an owl”)) Sorry, there was no photo, and a smartphone UG. In general, we disassemble the lamp, take out the desired plates, straighten them on the floor by smoothing a piece of the pipe, for example, or what else will fall under the arm. We cut each plate in half, two blanks for sections come out. There are three such profiles in the lamp, that is, we get six sections of 10 cm wide (in different lamps, the width of profiles is different). A short protection will turn out, but there will be enough for my selfish pots.
Mark, cut out the excess with scissors and knife in the ruler. With the help of a knitting needle, pliers and desktop tenses (the vice is not obligatory, they simply allow you to bend more equally), we form 9,000 loops. It is not very clearly visible on the finished product, but who does not know what the piano loops look like?)
bent on a mandrel of 2.4 mm (ceiling suspension from his favorite Armstrong), but then figured that the weight of such axes for loops will be a lot of shopping, this wire weighs 36 g/soup.m, therefore, in the end, I used a steel wire 0.35 mm from a PVC-goffra for axes. Loops dangle, and a dog with them, it does not affect anything, but almost nothing weighs.
On the extreme sections, the guides with studs made of steel wire 1.2 mm (straightened fixers of the broken lamp of the lamp) made. Transport position:
When I did and looked, I decided that crap) such a pin will keep the screen except in dense diarrhea with a weak wind. I will convert it to something more fundamental later. Thus, having fastened all sections, we get our wind protection, the outer matte side:
How is it in conjunction with my burner and boiler:
For a pot of 1.2 liters excellent, both in diameter and in height. For 1.8 liters (my second one from the set) will already be back, perhaps I will add another section.
Mine is happy! A very rough estimate shows that my wind protection was 2-2.5 times easier than the factory area, with the same functionality and complete free, except for three hours of time of leisurely manufacturing.
Speaking of functionality. Store screens are equipped with a stupid fabric cover, which does not protect from damage and is worn by dead cargo. The next article will be the right cover for the wind screen.
Light, budget screen for the burner. How to do it yourself? Details inside.
There are quite a lot of factory solutions on sale. Most of them have unacceptably high weight (200g), sometimes higher than the weight of the burner itself.

Wind protection for the burner
Those who go hiking in small groups often take with them a gas burner and a supply of gas cylinders to cook food. The bonfire, of course, is good, but it takes a lot of time, especially in the rainy or cold season. If in the evening it can still be diluted to sit by a friendly company near the open fire, then in the morning and day for cooking and tea it is better to resort to the help of a gas burner. One way to slightly accelerate the boiling of water on it is to use wind protection.
What is wind protection for a burner?
Imagine a fence made of rectangular metal sections that are fastened together using loops similar to door. Now reduce all this by ten to fifteen times (to the size of a gas burner)-and you will get wind protection. In a folded form, it takes up no more places than a rectangular school pencil case, and weighs about 300 grams. The main parameter of wind protection is its height. She should close the flame of the burner or will be completely useless. For burners, to which cylinders are joined using a flexible hose, less high wind protection are relevant. For the same burners on which the cylinders are wound are higher.
Imagine a sunny, not too windy day. Suppose that water in a half-liter pot in such weather boils in three and a half minutes. So with wind protection, this time will decrease to two minutes, that is, almost doubled. From this we can conclude: wind protection saves time and fuel. And here it is played not only by the fact that it protects the flame from the wind, the metal reflects heat inward and accelerates boiling water. Winning protection has another plus. it limits the flame, reducing the risk of burns of the hands of a tourist and the fire in general.
The disadvantages of wind protection are its own weight and weight of the cover, as well as the volume that it occupies in the backpack. Experienced tourists replace wind protection screens with improvised means. stones, logs, or even dig a hole in the ground. And you can protect the burner with the help of several seats or one tourist rug, let them melt. You can make a windproof screen yourself. from a dense foil.
It is obvious that wind protection should be taken on mountain campaigns, where there can be no question of a fire and question. Yes, it herself weighs three hundred grams, but in the end you will save gas and you can take a couple of cylinders less. In small one.day campaigns, wind protection can not be taken, but in severe heat carefully. there is a risk of overheating of the cylinder.
DIY windproof screen for gas burner
I bring to your attention a review of several methods of wind protection of a gas burner I tested using my own equipment. The discussion in the topic “Gas burner with wind protection” was ascending this testing. In general, once promised, he collected equipment and went to the Nahabin river today. There is a wonderful place there. Here in the pictures.
I chose this place.
First measured: boiling time of 1 liter of water in a tourist teapot without wind protection. Boiling time 498 seconds (8 minutes 18 seconds).
While boiling water, I managed to dig a hole under 7, 8 measurements. Once again I was convinced that Fiskars tools are tools with a capital letter.
The second measured: boiling time of 1 liter of water in an army pot without wind protection. Boiling time 785 seconds (13 minutes 05 seconds)!
Third measurement: boiling time of 1 liter of water in a tourist teapot when used as a wind protection of a tourist rug. Boiling time 474 seconds (7 minutes 54 seconds).
Fourth measured: boiling time of 1 liter of water in an army pot when using a tourist rug as a wind protection. Boiling time 521 seconds (8 minutes 41 seconds)
Fifth measurement: boiling time of 1 liter of water in a tourist teapot when used as a wind protection of a windproof screen. Boiling time 302 seconds (6 minutes 02 seconds)!
Sixth measured: boiling time of 1 liter of water in an army pot when using a windproof screen as wind protection. Boiling time 419 seconds (6 minutes 59 seconds).
Seventh measured: boiling time of 1 liter of water in a tourist teapot when used as a wind protection of the pit. Boiling time 426 seconds (7 minutes 06 seconds).
The eighth measured: boiling time of 1 liter of water in an army pot when used as a wind protection of the pit. Boiling time 615 seconds (10 minutes 15 seconds).
Total for a tourist teapot: 1) without wind protection 498 seconds; 2) in the rug 474 seconds (-4.8%); 3) in the screen 302 seconds (-39.4%); 4) in the pit of 426 seconds (-14.5%).
Total for an army pot: 1) without wind protection 785 seconds; 2) in the rug 521 seconds (-33.6%); 3) in the screen of 419 seconds (-46.9%); 4) in the pit 615 seconds (-21.7%).
Tatonka Faltwindschutz 10-Teilig windbreaker
We remove the packaging and get acquainted with the acquisition.
Before us is a folding aluminum windbreaker screen of the German brand “Tatonka”. Model Faltwindschutz 10-Teilig. 10. this means consists of 10 plates.
SHAWARMA BURNER INFRARED CERMAIC ,ADVATAGES,SHOWING INTERNAL PARTS,USED IN ALL KINDS OF MEAT EQUIPME
Dimensions folded: 24 x 8 x 2 cm.
In unfolded form: 8 cm 10 plates ~ = 80 cm.
Made of aluminum to reduce the total weight while maintaining reliability. Designed to protect the flame of a gas/gasoline burner from the wind. Folding, hiking. Significantly saves fuel and accelerates cooking.
Diameter about 25 cm. Accordingly, the ideal diameter of the pan/pans. so, is within 25 cm. It is possible, of course, more, but then there will be a “lumen” in the screen.
Yes, a protective screen can be done with your own hands. Compare!
It was. DIY windproof screen made of ordinary foil. Folds from one roll in 3 minutes. Enough for 3-5 days, if you carefully use and not bend.
It became. Tatonka Faltwindschutz 10-Teilig screen. Acquired once and for life, will last a long time.
Checking the screen in the case took place this summer, on a campaign to the Dukkinsky lakes in Arkhyz.
There is no need to count on firewood and cooking at the stake in mountainous areas. Therefore, in this campaign, they decided to cook in advance only on gas burners.
For breakfast, a large pot of water was boiled and “fast” porridge was brewed. The screen was pressed close to the pan so that the wind did not interfere with the flame.
Rice with stew is a favorite dish of the youngest participants in the campaign. The norm for five younger schoolchildren and preschool children is 2 liters of rice porridge, appetite in nature is excellent.
In the evenings, in the basic camp, the cooks had enough time to pamper everyone with the most delicious dinners, even paste with pesto sauce was drove. It was experimentally established that the screen paired with a large 4-liter pan can quickly feed 11 people (6 adults, 5 children).
Tatonka Faltwindschutz 10-teilig windmap-convenient, folding, lightweight. And at the same time reliable.
Use of solid soldiers and brass soldering
The solder allows you to perform an unusable tight connection of two metal parts by peculiar “gluing” them with some molten material. solder. The latter should show high adhesion in relation to the connected metals, that is, to be very “adhesive”, and have sufficient strength after solidification.
The melting temperature of the solder should be higher than the operating temperature at which the soldering product is operated; and at the same time lower than the melting point of the main material.
The gas burner is just needed in order to heat the solder and make it in this way quite viscous.
Obviously, for the convenience of working, its torch should maintain a stable shape and temperature.
The advantage of this tool is the ability to process zones with a large area. an electric steamer such a task will not be able to.
Super Simple DIY Propane Ribbon Burner For Boilers and Forges
At the same time, a simple low.power burner can be made without special troubles with your own hands.
With the help of a homemade burner, you can make a lot of useful things. Its capabilities will be quite enough to solder copper and brass vessels that make up radiators, interculfalters and heat exchangers, as well as for soldering using solid solders.
In addition, only with the help of this tool can the radiator can be disassembled in order to replace its core, as well as to replace it with honeycombs.
Such a burner is also useful during the repair of the body, in which the high temperature is not only not needed, but also very undesirable, as it can cause warning of this part of the car.
Perform a restoration of a small damaged area, stock up on a brass gap, carry out a “jewelry” rikhty. for all these works this tool will be quite suitable.
Significant heating will be needed in the event that it is necessary to dismantle the part set with an interference, that is, pressed.
It can be a clutch clip or some kind of sleeve.
In a locksmith business, using a gas burner, you can heat a metal workpiece so that in the end it turns out to be quite hardened. When carrying out welding work with some metals, the places of future seams should be warmed up.
Features and device of a roofing gas burner
For the installation of soft roofs, the best heat and waterproofers are considered to be melted materials. This procedure involves the use of a roof burner. Such work is very complex and long, but as a result you can create a very reliable and durable coating. Therefore, for work it is necessary to choose exclusively proven and high.quality equipment.
- What is a roofing burner
- Varieties of gas devices
- Compliance with safety measures
- Equipment manufacturers and its cost
- Self.manufacture of the device
Roof roof technique
The roof covering technology with soft roll materials with a firing method is produced in several technological stages:
- Preparatory stage: preparation of a concrete base, sealing cracks, garbage harvesting.
- Layout of the rolled base, connecting joints, gluing joints.
- Strengthening the base, planting it on a bitumen basis.
- With the help of a hand gas burner, the base is heated and the roll coating is laid, the joints of the rolls are pressed with a roller and additionally with mastic.
- With the help of the burner, the base and the first layer of the coating are heated, and the top layer is laid.
Homemade gas burners
The main components of the manufacture of powerful gas burners are industrial valves. They can be new, however, for a home.made device, it is enough to use those who are in the absence of gas leakage. They are designed to work in tandem with a 50-liter gas cylinder on propane with a corner valve and gearbox.
Burner with VK-74 valve
The device of this burner is shown in rice. one. The basis of the oxygen cylinder VK-74 is taken as the basis.A fitting-cutting fitting fitted end is installed by the output end, to the corrugated part of which the hose is connected from the cylinder. For part of the valve with conical carvings K3/4˝. to which it was connected to the gas cylinder, a cap with a prepared hole with a jetter is wound. You can use the finished version of the soldering lamp or gas stove.
The nozzle is made of a segment of a steel pipe 1/4˝ 100 mm long and welded to the cap on two segments of the wire ∅5 mm. Between the cap and the nozzle should be left a distance of 15 mm to flow air into the combustion zone. The mortgage of the wire holders regulate the position of the nozzle in order to achieve the center position of the flame.
The sequence of actions for the ignition of the burner:
- Open the valve of the cylinder;
- Bring the lit match to the snot and slowly open the gore valve;
- Control gas ignition;
- Adjust the flame with a valve of the burner
Homemade gas burner of this design has one drawback related to the location of the valve. The gas stream is directed in the opposite direction to normal position. Salnic seals experience constant gas pressure (WT.h. with a closed valve), so it is necessary to constantly monitor the tightness of the seals.
A burner converted from acetylene gas
If you have an acetylene cutter with a faulty oxygen feeding, do not rush to throw it away. It will also fit for the manufacture of a burner (Fig.). Gas mini burner
Mini gas burners are more suitable for working with small details. The minute is taken as the basis of the mini burner to pump up balls. It must be done in it, a little further than the middle of the needle.Some needles already have a similar hole, which significantly accelerates the process of work. Next, you need to take a syringe needle, and bend it for about 45 degrees in the middle.
The pointed end of the syringe needle is best sharpened so that it is direct. After that, it needs to be inserted into the ball to the ball so that one end goes through the hole, and the second protrudes from the large needle for several mm. The resulting mini design should be fixed using a solder. After that, the droppers must be attached to the bases of the two needles. Clips. droppers should be moved as close as possible to needles. In the resulting burner, they will play the role of gas and air supply regulators. They also need to be stuck together, and this is best done with the help of a thermal pistol. It remains only to connect a compressed gas source to the finished device, the burner is ready for use. Such a home.made gas burner can heat items up to 1000 degrees
You should carefully work with her, observing safety precautions
Gas burners for boiler plants
In accordance with the general provisions of the theory of burning gaseous fuel), gas burners are:
-partial preliminary mixing-diffusion-kinetic;
Gas burners are classified according to the following signs:
One of the essential features is the way to mix the burned gas with the air necessary for its combustion.
On this basis, the burners are the following three types.
Burners without preliminary mixing gas with air
Gas and air, in the amount required for combustion, are supplied separately through the corresponding canals of the burner. The combustible mixture is formed in the torch during the turbulent mixing of gas and air after they leave the burner.
For example, as a burner of this type, you can cite a tubular burner for low.calorie gases (rice.13). Gas flows through a gas manifold and pipes attached to it, and air through the opposite manifold. into the inter.tube space. Mixing occurs in jet streams at the output of pipes.
Such burners are used to burn low.calorie gases in large quantities and in furnace equipment, when you need to have a stretched luminous torch with a more uniform heat transfer along the length of the working space of the furnace.
Gas preliminary mixing burners with air
Burners working on the principle of kinetic burning are used in cases where it is necessary to burn gas with high thermal voltage of volume with minimal chemical short.burned and with a short hard.visible flame, preliminary mixing of gas with air goes in mixers, from which the finished mixture enters the burner. This type includes tunnel and other types of burners of a homogeneous gas-air mixture obtained by preliminary mixing of gas with air in mixers of various structures.
In industry, the injective burners of the tunnel type are widespread, which ensure the abstainment of the constant ratio of gas and air expenses and allow the burning of dusty gases. Burners are more heat.resistant and have increased throughput with small resistance.
Burners with partial mixing of gas with air
These burners are equipped with shortened mixers in which partial mixing occurs. The mixing continues and ends in the torch during the combustion process.
Burners working on this principle are widely used in the energy sector for burning natural gases.
In the burners with partial mixing for low-calorie gases due to comparable gas and air expenses and air are supplied with alternating flat streams through channels in the fork, in the channels of which the mixing and burning begins. The process of mixing and combustion continues and ends in the weekend channels. The section of the tunnel of the burner is determined by the number of combustion products and their speed taken within 30-40 m/s.
According to the method of supplying air, the burners are divided into injective and stubborn (with forced air supply). In accordance with this, distinguish between low gas pressure burners (up to 5 kPa), average (5 kPa- 0.3 MPa) and high (more than 0.3 MPa). Injection burners are only of low and medium pressures.
Fuel combustion in the form of gas is determined by the way and speed of its mixing with air (oxygen). For small heating boilers, usually the installation of a gas heating system involves atmospheric and fan burners.
The principle of operation of the gas burner is shown in rice. 16.
Examples of burners and their main parts are shown in rice. 17.
In Fig. 18 shows the basic schemes of gas burners. In the injective burner (rice. 18, a) The gas arising from the nozzle ejects (sucks) the air and mixes with it. The gas-air mixture in the injection burner burns in the nozzle (tunnel) from refractory material directly adjacent to it. Due to the high temperature of the inner surface of the nozzle, the burning of the finished gas-air mixture proceeds almost instantly and ends inside the nozzle. For this reason, such burners received the conditional name of the flame.
The volume of the combustion chamber adapted to the free gas burning can be significantly reduced, and when choosing the dimensions of the camera, they do not proceed from the need to complete the combustion process in it, but from the condition for obtaining the largest area of the heating surface.
