Hello dear readers. Did you know that a heater for a gas cylinder is simply necessary in cold weather. And what can happen if the balloon freezes. How to prevent this and how to warm it up?
The situation on the street
Warming a gas cylinder in winter is a particularly sensitive issue. It is very relevant for fishermen and tourists. He also worries the owners of private houses and buildings, the cylinders of which are on the street.
It is also important here at what temperature propane gas freezes in cylinders. Already at -15, the liquid substance in the cylinder freezes. Gas production slows down. And the work is broken gas appliances. For example, when hiking or fishing, there may be problems with burners, fixed annuity interest rate in the country - with a portable stove.
At -30 there is no gas production at all.
And the next question arises - is it possible to heat propane tank so that gas units work better. As part of liquefied gas play and earn money a couple of hydrocarbons: propane and butane. Evaporation of the former occurs at extremely low temperatures. Evaporation of the second - already from -14-15 degrees.
In order for the cylinder to function well in winter, the composition should be about 70% propane.
It is possible to heat the cylinder, but within the permissible limits.
How to insulate a gas cylinder on the street? How to warm a gas cylinder on the street? These sensitive questions are different solutions. The following are some popular methods:
- The use of disposable chemical heating pads. They heat up to 35-40 °C. It's extreme allowable rate for balloons. The duration of the operation of such heaters is 6-7 hours.
- Use of reusable salt pads. But their norm is about 50 ° C. It is somewhat dangerous to heat the cylinder with them.
In principle, the gas cylinder heater can be anything. The main thing is that its functional temperature does not exceed that of the cylinder. This rate is displayed on the label. The balloon needs constant monitoring. financial assistance grants It should be probed periodically. If it is a little warm, you need to reduce the thermal effect on it. If it gets too hot, immediately stop heating it.
Often, at dachas, the owners place the cylinders in special devices, these can be boxes, lockers, etc. And here a logical question arises - how to insulate such a cabinet for gas cylinders?
Here is the most effective method– apply the BH Thermal system. It costs between 7000-8000 rubles. Can be used domestic analogue TEO-GB1 for about 5000 rubles. This is a lightweight non-flammable stocking that provides heating. It completely covers the surface.
How to warm up a gas cylinder when it freezes? If your gas cylinder is freezing up, then you need to apply any of the following actions (or all):
- Smoothly pour over the balloon hot water. You can act on it with hot steam. The cylinder valve is closed. This is partial heating. In order for the payday loans gallatin tn part to warm up completely, it must be removed, transferred to a warm room for 20-40 minutes. In no case should heating be carried out with an open flame.
After the procedure, the moisture concentrated there is removed from the gearbox by blowing. Before purging, its hose is removed.
- Transfer the entire container to a warm room. This must be done immediately when the gas cylinder is covered with frost. The cylinder must be kept indoors, preferably near the battery, until it warms up. You can connect a special electric heater.
- Apply saline or chemical heating pad. That is, hiking methods of heating.
By applying these methods, you will solve the dilemmas of what to do if the gas in the cylinder is frozen, if the cylinder is frozen, etc.
And to avoid such troubles, the cylinders need to be concentrated in warm rooms or heat well.
In the first case, a heated floor technology should be installed under the cylinders on the basis of the existing heating system.
In the second - to use efficient heaters.
- Management will improve significantly.
- Reduced consumption of liquefied gas
- Pressure develops inside the balloon - this is a consequence of the formation of convection heat.
- A pure liquefied fraction will be produced. So gas is saved up to 30%.
And for tourists, special devices are optimal, for example, a nozzle-heater for a Pyramid gas cylinder
It fits many burners, tiles and stoves. It is often used to heat not only tents, but also small buildings. It is made from chrome steel. Its weight is 120 grams.

Question with HBO in winter
What problems can there be with HBO in winter? If the gas-balloon equipment is installed correctly and is serviced in a timely manner, then the difficulties with the operation of vehicles with LPG in winter time does not occur.
And the reasons for the difficulties may be incorrect installation or low-quality fuel. Usually in winter in liquefied gas they develop a proportion of propane up to 80%. Reason: It evaporates remarkably. If summer gas is poured into the car, its evaporation will not occur, pmi 2013 the car will run on gasoline.
In winter, liquefied gas is consumed more intensively, because the percentage of less dense propane is greater than the percentage of butane. The driver is forced to press harder on the gas.
The greatest difficulty for HBO in cold weather is gas condensate. These are oily substances that remain in the gas after its poor-quality purification. When it is liquefied, these substances are dissolved in it. They freely penetrate into the reducer-evaporator, having passed the filter. In the cash advance businesses reducer, the propane-butane composition is affected by temperature, and it is converted into gas. And the substance does not evaporate and can get into the reducer and nozzles.
Why freezes gas reducer? The most common cause lies in the indicated oily substance. Gearboxes that have direct control over the dosing valve (multi-valve) are most often affected. As a result, the HBO multivalve, the gearbox itself, and other parts freeze.
When this contamination penetrates into the space between this valve and the master cylinder, the valve becomes stationary, the gearbox does not provide the required pressure, and the gas does not flow well to the nozzles.
If your car has such parts, refuel only at reliable gas stations.
Oily condensate also harms the injectors. Their petal versions, which are spring-loaded by a metal membrane, suffer the most. They just stick to the electromagnet. The gas is not dosed out the intake manifold. As a result, it is spent more, the nozzles break.
Modern versions of the injectors have a pin solenoid gas valve (EGC). They are less susceptible to low-quality fuel. But in the cold, oily mixtures do not crystallize, they become sticky. Because of them, the nozzle valve is not paralyzed. As a result, the engine may stall.
Question with cylinders in cars
Why does the gas cylinder on the car freeze? Firstly, this means that the gearbox freezes. The reasons for its freezing are as follows:
- in the cooling technology, the content of a special liquid - antifreeze, has decreased,
- wrong hoses,
- water pump problems
- the thermostat is malfunctioning,
- difficulties with EGC,
- gear diaphragm broken
- condensate has entered the gearbox,
- gas leak.
When there is little antifreeze, air jams appear.
When hoses are not properly sized, they may become clogged or missized. In this case, the circulation of antifreeze stops, and the gearbox freezes.
When the water pump is faulty, this is also a sign of impaired circulation of a special fluid. When the pump is not working, the cooling system is interrupted. The result - the gearbox freezes.
If the thermostat is not working properly, the following symptoms may appear:
- engine overheats,
- the engine takes too long to warm up,
- antifreeze gets hot
If there are difficulties with the EGC, the power contact may break or the wire may oxidize.
If there are problems with the diaphragm (usually rubber), the gas is sent to the cooling system, frosting over the gearbox and some pipes of this system. The diaphragm needs to be replaced.
Gas leakage occurs due to leaky contacts. As a result, the gas supply pipe freezes over. Freezing occurs at the leak sites. Sign - there is a smell of gas. You need to open the hood and check all connections with soapy water.
When the gearbox rarely undergoes maintenance, and does not drain the condensate on time, the filters become clogged. It is necessary to arrange maintenance of the gearbox at least once a year.
Another very relevant question is at what temperature does gas freeze in a car?
Here the indicators are as follows: propane freezes at a parameter of -40 C, butane - 0 C.
And the composition of butane and propane usually freezes between the specified limits. Therefore, in winter, the composition contains more propane.
Conclusion
In order for the gas cylinder to work properly in winter, it must be efficiently heated.
Our goal is to achieve a stable evaporation of gas in a disposable cylinder, without allowing its temperature to drop below the boiling point. All of the following applies in particular to stoves and heaters not equipped with a cylinder heating plate.
Unsafe methods, as well as methods that require changes to the equipment, will not be considered in this article.
Required minimum
First of all, you should clarify the weather forecast for the day of fishing at the place of fishing. And, depending on what weather forecasters promise the temperature, take cylinders with the appropriate gas mixture with you (for more detailed information cm. ). If possible and the equipment allows, it is preferable to use cylinders large volume(450 grams). It has been verified that the gas in them evaporates better (the volume of vapor is directly proportional to the volume of the liquefied part).
The heater should be equipped with a heat-insulating stand. Otherwise, if it just stands on ice, a considerable amount of heat radiated by it will go into the water, since ice has good thermal conductivity (more on this at the end of the article). Without a stand, the heater will also melt ice under it and gradually sink into it.
As an insulator, a piece of plywood, painted with drying oil (or its modern analogue) for waterproofing, is perfect. Insulation efficiency can be improved by gluing the top side of the plywood food foil- then the heat will be reflected from it.
The size of the stand should be provided so that the cylinder is on it and it completely covers it from ice. The foil in this case will even play the role of a conductor of a certain amount of heat to the balloon.
Insulating the cylinder during the operation of the heater not only makes no sense, but is also harmful, since the mixture cools when the gas evaporates. Close the balloon from external environment- means to make a miniature model of a refrigeration unit out of it.
But on the way to the place of fishing, the insulation of the cylinder (especially the one that is supposed to be used first) will be useful. Otherwise, it may happen that the gas freezes and it will have to be heated before starting the heater. The best option here - to make a box for the cylinders from some thermal insulating material. But you can just put one balloon in your bosom (the rest will warm up in the tent).
For the same purposes - if you get to the place of fishing by car - in cold weather, the cylinders should not be kept in the trunk, but should be put in the salon, otherwise (especially if there is a good frost in the yard) - they will definitely freeze. Checked.
Artificial balloon heating
Suppose we successfully started the heater, but the power of its flame began to decrease over time. This suggests that the temperature inside the cylinder reaches the point at which the gas stops evaporating. Now is the time to take care of an additional heat source for heating the cylinder.
For tiles and heaters, where the cylinder is connected through a hose, the following method helps. The balloon is placed in a cuvette into which water is poured from the hole.
If the mixture in the cylinder is based on isobutane, this works great, because the temperature of the sub-ice water is about zero, which is more than enough to evaporate this gas: its boiling point is -11.73 ° C. In the case of butane, this trick also works, since its boiling point is -0.5 ° C, which is not much, but lower than the temperature of the water from the hole, however, according to some anglers, the gas still freezes because the cylinder cools quickly . Apparently, here you will have to heat it differently, as in the case of devices, the design of which does not allow you to slip a cuvette under the cylinder.
AT recent times cheap disposable chemical heating pads appeared in stores in the form of insoles or plates with an adhesive side, the composition of which, upon contact with atmospheric oxygen, oxidizes and releases heat. Such heaters are heated up to 35-40 ° C (a similar temperature is indicated as the maximum allowable for the operation of disposable cylinders). Why not use them to heat the cylinder? Moreover, the operating time of the heaters is 6-7 hours.
Some anglers and hikers use reusable salt heaters to heat the tank. Mentions of this can be found on the forums. However, the operating temperature of salt heaters is around 50 °C, so there is a small risk of overheating the cylinder when using them.
In general, this risk will always exist if the heat source used to heat the gas is heated above that allowable temperature as indicated on the cylinder label (usually 40-45 °C, depending on the gas mixture). Of course, until the air warms up in the tent, the risk of overheating the balloon is minimal. However, a stably operating heater can significantly increase the temperature of the enclosed space, which will lead to an increase in the temperature of the cylinder. Of course, up to +30 ° C and above, no one will warm the winter tent, since this temperature is unlikely to be comfortable for a warmly dressed angler. And the constant evaporation of gas cools the cylinder, making it somewhat colder. environment. However, if the heat source used to heat the cylinder is strong enough, unsafe temperatures may well be reached.
Conclusion: theoretically, the cylinder can be heated with anything, however, if the operating temperature of the heat source is higher than that indicated on its label as acceptable, the cylinder must be monitored, periodically feeling it. As long as it's cold, don't worry. If it suddenly becomes a little warm, the effect of heat on it must be reduced. And if it is noticeably warm, or even hot, it is clear sign overheating, so you should immediately stop heating the cylinder.
It is clear that feeling the balloon will have to be distracted from the fishing process, and with a good bite, you can completely forget about it. So it’s better not to use everything that can overheat the cylinder, because a small positive temperature is enough for stable evaporation of gas.
Most likely, disposable heating pads with operating temperature up to +40 °C — best option. In the case of their use, the insulation of the cylinder (along with a heating pad, of course) is justified and in demand. Not only will this improve heating, but it will also allow you to use smaller heating pads.
A little about tent insulation
Not only by heating it is possible to exclude the freezing of gas in the cylinder. As you know, ordinary single-layer tents keep heat “so-so”. But they are easy to hem from the inside with a padding polyester and another layer of fabric. After that, the tent will warm up faster and keep warm many times longer, but it will become heavier.
In addition to the walls of the tent, a significant part of the heat is also absorbed by the ice. The thermal conductivity of frozen water is much higher than that of liquid water, and at -20 °C is actually equal to the thermal conductivity of granite (2.4 W/m*K). It's funny, but it turns out that snow can play the role of a heat insulator here, because its thermal conductivity is approximately equal to the thermal conductivity of wood (0.15 W / m * K). Therefore, if the ice is covered with a layer of snow, heat loss in the tent will decrease.
However, snow always has negative temperature, so its heat-insulating properties should not be relied upon. It is better to equip the tent with a homemade floor, which can be cut from a dense isolon one and a half centimeters thick. This will not only insulate the angler's shelter, but also eliminate the melting of ice and snow under it.
Product Description:
It is made in the form of a flexible belt with a width of 145 mm made of soft silicone rubber with springs at the end for a secure fit. The gas cylinder heater is designed to maintain the temperature of the lower part of the cylinder around 30°C using a thermostat. It is additionally equipped with shock sensors that turn off the heating when the temperature exceeds 35°C, 45°C, 75°C. Shock sensors are placed in a circle. The heater power is 250W. The electric heater is used for heating steel welded cylinders for liquefied gases with a volume of 27 and 50 liters, made in accordance with GOST 15860-84.
Application area:
An electric heater is used to efficiently generate the entire volume of the gas mixture and maintain a stable pressure in the cylinder. The main working fuel for gas equipment is a liquefied hydrocarbon gas - a mixture of propane and butane. At work roof burner there is a decrease in pressure and the liquefied gas begins to boil and quickly evaporate. In this case, the remaining liquefied part is cooled. When the gas temperature in the cylinder is below -0.5°C, no evaporation of butane occurs, therefore, from 20 to 60% of the gas remains underused in the cylinder, depending on the ambient temperature. This residue is commonly referred to as condensate and is drained off prior to refueling, resulting in economic losses.
The electric heater provides heating of the bottom part of a cylinder. Such heating normalizes the operation of the roofing propane burner, providing a stable pressure on the gearbox above 1.5 atmospheres and the production of the entire volume of gas. The heater is recommended to be used at air temperature up to +30°С. When working with the heater at temperatures of about 0°C and below, we recommend additionally covering the heater and cylinder walls with foamed roll insulation.
During operation, the electric heater must fit snugly against the walls of the steel cylinder, this ensures the normal operation of the thermostat and shock sensors. It is forbidden to use for heating rusty cylinders and with peeling paint. Connects to a standard 220 V network.

Information quotation:
*******************************
“For safety reasons, when used in replaceable gas cartridges, as a rule, isobutane is used. Its boiling point is -10 C. Pure propane has a boiling point of -42 C; according to safety rules, a cylinder for its storage must withstand a pressure of at least 25 atm. (pressure of saturated vapors of liquefied propane is 16 atm., the wall thickness of the cartridge should be hoo!). n-butane (ordinary butane) has a boiling point of -0.5 ° C, it liquefies easily, but at 0 ° C its saturated vapor pressure becomes lower than atmospheric pressure and it refuses to evaporate (with the intensity necessary for jet combustion). For winter, a mixture of propane (from 25 to 40%) and butane (from 60 to 75%) is used in cans (for imported burners), for winter they are more effective. This information is written on the balloon. In domestic cans (Kazan), only isobutane is used, it can be used in winter with a slight (up to -5..8 C) frost. In Korean, the same model is n-butane, it will not work below 0 C.
In household gas cylinders(capacity 6, 12, 27 and 50 l) for gas stoves industrial mixtures of propane and butane are used - 75% propane and 25% butane for winter and 40% propane and 60% butane for summer"
********************************************
Extensive experience has shown me that all (or almost all) small-sized gas cartridges work stably only at an ambient temperature above + 7C. The fact is that the process of evaporation of gases from a liquid state greatly cools the evaporation zone, and the cylinder freezes itself - it becomes covered with frost. The volatile part of the gas burns out, then the gas evolution stops and the burner goes out. Three-quarters of the unused liquefied gas remains in the cylinder.
So far, not a single industrial gas structure has been developed that can operate in frost with a low dead weight. I know of at least four accidents caused by this:
1. At night, the frost hit -20C. The fisherman lit the gas burner and went to bed. Half an hour later the burner went out. Deeply frozen. the man dropped all his equipment and ran 6 km to the shore. There, in the car at the base of Krenitsa, he warmed up and went home, mother night fishing.
2. Three fishermen in an umbrella tent lit a gas burner and sat down to fish. Half an hour later the burner stopped burning. Having cursed at the producers, they put the burner “to the wall” without closing the valve, and continued to fish - it was BEATING! Gas slowly flowed out of the burner and when they
smoked then FUCK!. People were almost not injured, the tent was in the trash, the fishing was ruined.
3. The husband took his wife fishing with him. In order not to freeze it, I bought a gas burner and a can. We fed, started fishing, pecked. The burner went out after half an hour, the wife began to freeze. They called a snowmobile and drove home. The wife has been sneezing for the second week and “saws” her husband.
4. My nephew and a friend in the Gulf of Finland lit a gas burner at night. She went out after half an hour. The comrade, freezing, fled ashore and went to spend the night in a hotel. Plemyash climbed into the sleeping bag and fell asleep comfortably until the morning. Sokolov! Comrade more with nephew
doesn't go anywhere.
The thermal insulation of the canister does not help, but accelerates the process of stopping the evaporation of liquefied gas. Realizing that an influx of heat was needed to the spray can, I began to raise the burner in the tent as high as possible: the burner fell, turned into a flamethrower, and I got burns on my legs. Then I began to develop the heating of the spray can. After several prototypes, I calculated and made a small and simple additional design "HEAT PIPE" suitable for mobile gas burners and lamps.
I was asked: "Describe the process of making your stray." I didn’t like the word “stray”, but I conscientiously described everything I could: I don’t want someone, suffering from their lack of foresight, to swear at me: “I didn’t give out the secret how the bells pour!”
SO DESCRIPTION OF HEAT CONDUCTOR:
With this design of the heat conductor, I use standard gas cylinders and burners in frosts down to -30C. The gas does not stop evaporating and burns out completely! The function of the heat pipe: take heat from the burner, deliver it to the can and heat the can.
As a material, I used an aluminum bus (electrical conductor) from electric cabinet(ShS - power cabinet). You can buy a tire at the ETM store (electrotechnical materials):
I took a used tire, having estimated in place required size. I gave the middle part of the tire a shape that goes around the cylinder-burner transition vertically.
I bent the lower heat-releasing part along the diameter of the can.
After bending, I cleaned the heat-releasing part with a "grinder"
It turned out very tight!
And already at the very top I made a bend at a right angle in order to bring the heat extraction closer to the burner.
Cut off the excess with a hacksaw:
In order to avoid heat losses, I thermally insulated the middle part of the Heat Pipe with an asbestos cord.
I did a lot of experiments and this is the fourth option - it suits me. I wind the lower part of the heat conductor to the balloon with a piece of porous material from the “Slimming Belt”. You can do this with any rope. For the cylinder, I specially sewed a heat-saving non-wet cover from polyurethane foam and nylon (like a saucepan - red).
Field trials quietly moved into operation.
The burner with HEAT CONDUCTOR works perfectly in any frost!!! In this case, all the gas in the cylinder burns out without residue!
