A bit of history.
During the First World War, millions of soldiers froze in the trenches, and during the four war years, the inventors of the United States, Japan and England patented several versions of pocket liquid heaters. The principle of their operation was simple: catalytic flameless oxidation of alcohol or gasoline. Platinum served as the catalyst in all cases. The Japanese heating pad looked like a cigarette case, inside of which there was a reservoir filled with cotton and a platinum gasket. Holes were drilled in the hull to supply air to the kata.lysator and removal of gaseous products of combustion. To start the heating pad, alcohol was poured into the tank, which soaked the cotton wool. Then the catalyst was heated with a match flame, and the catalytic reaction began.
The Soviet industry produced a gasoline catalytic heater GK-1, which, when fully charged, could give off heat for 8-14 hours at a temperature of up to 60 ° C, i.e. at the pain threshold.
Device and principle of operation
The heating pad consists of a reservoirFilled with cotton wool, nozzles with a mesh cartridge in which the catalyst is placed, and covers with ventilation holes.
The principle of operation of the heater is based on the release of heat during the flameless oxidation of gasoline vapors in the presence of a catalyst. Gasoline vapors from the tank pass through the catalytic cartridge, where they are oxidized by atmospheric oxygen (burn without a flame) on the surface of the heated catalyst. Oxidation products exit into the ventilation openings of the cover. At the same time, through the ventilation openings of the cover to theThe surface of the catalyst receives air containing oxygen. Catalytic grid - catalyst, made of glass fibers coated with platinum - this is the most important part of the heating pad.
Fuel for heating pads - gasolines of the highest degree of purification: gasoline for lighters and Kalosha gasoline are well suited for these purposes. The use of other types of fuel can lead to rapid clogging of the catalytic mesh, which will affect its efficiency.
Helpful Hints
before using grails, in a catalytic cartridge, it is advisable to ignite the grid over a gas primus burner, spirit lamp, over everything that gives a clean fire without smoke and soot - just heat the grid red-hot and cool it in air. nozzle (otherwise, gasoline will simply evaporate in vain), for this purpose, you can use a piece of plastic film in cold conditions, before starting the heating pad, it must be brought to a temperature of 10-15 ° C (warm up) with your breath, hold it in your hands, in your bosom, etc.) - this is necessary for the concentration of fuel vapors on the catalyst grid; warm up the grid in the catalytic cartridge for 10-15 seconds; thus preventing the body of the heating pad from cooling down, however, do not forget about the air flow necessary for the normal operation of the heating pad. Use the heating pad together with the fabric bag included in its kit. It is designed to regulate the flow of oxygen, fallinginside the heating pad, as well as to avoid burns when using it. .To. there it is often LEADED, i.e. contains an additive - tetraethyl lead (TES). Which "kills" the catalyst. Inhalation of thermal power plant vapors causes severe damage to the nervous system.
