Gas appliances are designed for the combustion gases under constant conditions, is fed into the burner air (oxygen), in the case of methane (CH4) ratio of about 8 cubic meters of air per 1 m3 of gas. This design ensures the correct ratio of the burner of the appliance (stove, heater, or boiler), but also requires a constant pressure of gas (methane at about 200 mm water column).
Homemade appliances often lack the very important aspect - safety relief valve, which prevents the rise of pressure above the safe level. Therefore, described the explosion ....
The pressure required will ensure open hose, connected to a tank of gas (ie gas holder) and submerged under water 200 mm deep .. hose would work well as a safety valve - blows away the excess gas into the atmosphere.
Several years ago I had seen a description of a small gas works, designed for the use of natives in Africa, performance was perhaps 3-5 m3/day. More energy-efficient than wood burning in the primitive fireplace.
Gas could be implemented as a plastic bag, and could be inappropriate to restrict the oxygen in the gas at the rotting process.
ATTENTION! ATTENTION! gas is very dangerous medium, ATTENTION!
