Where and what is it used for
Taking into account the processes that occur during the operation of heating equipment of this kind, its use in a room where people are regularly located should not be. A gas heat gun is commonly used in industrial, warehouse, construction, agricultural facilities.
We watch the video, scope and principle of operation of the device:
With regard to functional applications, it is equally popular to use this technique as a heater for large-scale areas and for technological drying. By the way, the last of the named possibilities, which the gas cannon possesses, makes it possible to significantly speed up the execution of construction work. Using this technique, you can quickly dry the treated surface and prepare it for further manipulations.
Rules for using the gas cannon
Heat gas cannon very popular among Krasnoyarsk buyers — many Krasnoyarsk organizations have already bought or are planning to buy a heat gas cannon in Krasnoyarsk, because a heat gas cannon offers its customers an excellent combination of low price, low weight and high calorific value.
Gas cannons in Krasnoyarsk: powerful and cheap heating
The most important advantage that they have gas cannons - this is a high heat output, which opens up excellent prospects for heating large rooms. The power of some models of gas cannons reaches a huge value - 101 kW, while the weight of even such a super-powerful gas cannon does not exceed 23 kg. Such excellent weight and size characteristics make gas cannons extremely mobile devices, allowing you to organize heating at a new facility in almost a matter of minutes.
Another important point - for gas cannon does not need a lot of electricity. Many commercial premises (production, warehouse, etc.) are experiencing big problems with allocated electrical capacities: in projects under construction they are often not allocated at all, and finished buildings are connected to electrical networks with very large restrictions (rarely anyone has officially allocated electrical capacities more than 30-40 kW).
In this case, modern gas cannons: powerful, lightweight, easy to operate. And besides, heating with the help of gas cannons turns out to be much cheaper than similar heating with a diesel heat gun or even more so with an electric gun (and in terms of thermal power, electric guns provide much less opportunities - the largest electric gun has a thermal power in the region of 35- 40 kW).
For the price of heating a gas cannon there is no equal at all. For comparison: at current prices for electricity for legal entities (4 rubles per kW), for diesel fuel (27 rubles per liter) and for liquefied gas (15 rubles per liter), the cost of 1 kW of heat generated for a heat gas cannon will be 1.8 rubles, for a diesel heat gun - 2.4 rubles, and for an electric cannon - 3.9 rubles!
Distinctive features of work and design
A gas heat gun operates on a similar principle to its counterparts: air passes through the combustion chamber or heating elements, which is supplied to the device by means of a powerful fan. The latter, in turn, is set in motion with the direct participation of the engine. A gas heat gun differs from an electric one by the presence of a burner.The fuel is ignited using a piezoelectric element, which is used today in gas boilers.
The device and design of a gas cannon
The high-performance gas cannon is powered by a liquefied gas cylinder. As it becomes empty, it must be replaced. At an average level of performance, the cylinder can be enough for a long period of time - up to 50-60 hours of continuous operation. In this case, a compact gas heat gun consumes 0.8-1 l / h.
Heat guns: classification and main differences
Depending on the performance, heat guns are divided into household and industrial ones. Household equipment is usually designed for a smaller space and is more economical to operate. Industrial heat guns are suitable for heating large spaces or buildings with low thermal insulation. In addition, heat guns are very often used when installing stretch ceilings, where it is necessary to quickly heat the canvas before installation.
Depending on the energy carrier, heat guns are divided into several types.
Heat gun electric
Operates from a network with a voltage of 220 or 380 V. It is characterized by low power, small overall dimensions and is easily transported. The main advantage of an electric heat gun is the absence of combustion products and mobility. In addition, it does not require refueling and can be used to heat residential or small industrial premises.
Gas heat gun
Uses the energy of gas combustion to heat the heat exchanger. Such guns are usually more powerful, more economical and do not require the removal of combustion products. Gas-fired heat guns need to be connected to a gas cylinder and periodically refueled. They can be used to heat rooms with a high degree of humidity.
Diesel heat gun
It can have a closed or open combustion chamber. Diesel open chamber heat guns are used only in well ventilated areas. Heat guns of indirect heating allow you to remove combustion products from the room by means of a corrugated pipe.
Waste oil heat gun
Multi-fuel heating equipment. The waste oil heat gun is economical and suitable for heating garages, warehouses, industrial premises where there is a large amount of waste fuels and lubricants.
Infrared heat gun
Uses infrared radiation for heating. It can be used for heating solid objects, defrosting, efficient heating of working areas. Infrared heaters do not dry out the air, they are safe and economical.
Heat guns with water heat source
They consist of a fan that blows a heat exchanger connected to the centralized heating system. Provides fast and even heating of the room. They are characterized by high efficiency and economy.
How to choose the right one?
First of all, to determine the performance of such equipment, it is necessary to find out what power the device is suitable for performing its functions with minimal losses. For this, the parameters of the room where the compact gas heat gun will be used are determined.
Having calculated its volume, it is necessary to find out exactly how good the thermal insulation of the object is. For the calculation, it is recommended to obtain the value of the coefficient, which will be equal to 1 with a good level of insulation or 4 in the absence of thermal insulation. A value of 2 or 3 characterizes the average level of room insulation.
To determine the power, you also need to know the coefficient of temperature difference between the outside and inside of the object. This subtracts one value from another. Now you can multiply the volume of the room and two factors (insulation and temperature difference).The resulting value is measured in kcal; to convert it to kW, it is enough to divide the result by 860.
A high-performance gas heat gun is also selected based on the speed of work. The more efficiently the device functions, the faster the room will warm up. In order to roughly imagine how long the equipment will work without shutdown, you should pay attention to the selection and fuel consumption.
Frequently bought models
Model Master BLP 10M
The gas compact heat gun of the manufacturers Master, Balu, Moller is in demand more than others. For example, the Master BLP 10M model is designed for 10 kW, its speed corresponds to the value of 300 cc. m / h, fuel consumption is very modest - 750 g / h.
The device is single-phase, weighs only 4 kg, and operates on liquefied propane. If you need to pick up gas cannons, the described model will cost 4,700 rubles.
On the same site, you can choose an order of magnitude more productive device of the same brand, but at a very modest cost. For example, the Master BLP 53M gas cannon is offered at a price of 10,900 rubles, but the user receives a unit operating at a speed of 1450 cc. m / h, fuel consumption will be higher - 3 780 g / h. The power of the unit is impressive - 53 kW. All models described are equipped with a piezo ignition.
Watch a video review of the Ballu BHG-20 S model:
Another option is the Ballu BHG-20 S model, offered at a price of 5,000 rubles. It works with propane and butane, the maximum power value is 18 kW, while the fuel consumption is relatively low - 1 200 g / h. The capacity of the device corresponds to a speed of 500 cc m / h. The more power and the degree of efficiency of such a technique, the larger its dimensions will be.
Today, users often began to select equipment on the Internet, the gas cannon was no exception, the Leroy Marlene store does not offer the widest range of such equipment, but the products are of high quality.
Principle of operation, types
This is equipment for heating air indoors, on sites, in which heat energy is generated from the combustion of liquefied gas, usually propane or butane.
The cannon consists of the following elements:
- A fan that blows cold air.
- Gas-burner.
- Ignition.
- Heat exchanger.
- Thermostat.
- Electric motor.
- Control system.
The fan is brought into operation by means of electric motor... It blows cold air into the interior of the appliance. Then, with the help of a torch, electric ignition or piezoelectric element, the gas is ignited. Hot air currents under pressure go outside and heat the room. Most modern guns have a thermostat that allows you to regulate the heat supply.
Gas cannons are:
- Portable - small in size, have a handle for carrying, low power, used for heating small areas.
- Mobile - have castors or stand on wheels.
- Stationary - are permanently installed in premises with a large area (sales rooms, workshops, warehouses).
Heat guns direct heating are in great demand. They work like gas burners, quickly heat up the air, but burn oxygen and emit harmful combustion products directly into the room.
Expensive, bulky and less popular - cannon indirect heatingwhich has a chimney. It removes the products of gas combustion outside the room. Therefore, the device does not pose a threat to human health.
gas heat guns
Since questions periodically appear, then a small report. Directly heated gas heat gun is used to quickly create comfortable thermal conditions in a room. Ideal for a garage, let's say it was locked at -20, change the pads, drove the car into the garage, turned on the gun, after 15 minutes the air (but not the surrounding objects and the car) warmed up to positive temperature and were repaired. For preheating the summer cottage: they turned on the gun, turned on (melted) the main heating power, heated the air so that you can comfortably stay in the room, waited for the main heating to return to normal mode. Features. 1) Eats really robust - 15 kW gun eats about 1.5 liters of (liquid) gas per hour.2) The humidity in the room rises strongly, the walls will feel damp to the touch, because one of the combustion products is superheated water vapor. 3) Very noisy, talking during work is tense. 4) The complete hose is short and made of PVC, I recommend replacing it with a rubber (gas) hose of the required length. 5) Because the balloon is in the cold, then in the process of work it will be covered with frost, and even an ice crust, I did not bother about this, and categorically would not beat it off, and even more so to warm the balloon with boiling water, people complained ... -15 (provided that both the cylinder and the gun are stored in the cold), it is difficult to start, due to the worst gas evaporation. Either a long jabbing until the giblets of the cannon warm up, or (IN NO EVENT IS AN ADVICE, just a personal example) covered the rear (suction) grate with a piece of cardboard, lit it and waited a little to clean it, then it doesn’t go out. 7) While you are awake, oxygen will not burn a lot, the main thing is not to fall asleep with it in a closed room. 
The included safety valves against gas leaks only work to tear off the hose, if the hose is slowly poisoning, the valve will not work, so check everything yourself carefully. 9) When you first turn it on, something burns there, so there may be a specific smell. 10) If it stinks of gas during work (as I said "gas fumes"), change the gas station, something they pour over there, most likely it will stop stinking. 11) Household gearboxes "frog", "baltika" and the like are not suitable, because have too little consumption. The gun will not work with them and do not even try to force them. I have not tried it myself, but there are thoughts that you can try BPO-5 and the like, as with welders. 12) Finally, read the instructions to the end, especially the shutdown procedure. And I would not strongly advise to drink under this device.
