Coal bed gas is a kind of burnable gas without any color, taste and smell. It will explode if the concentration ranges at 5%~16%, and if oxygen larger than 12%, it will also explode when meets the naked light or temperature between 650℃ to 750℃. Explosive power will be biggest if concentration is 9.5%.It will not explode if concentration larger than 169,6. 11 was generated by coal or rotten plants and exist in two states: absorbing and dissociate. China is the third coal bed gas reserves country in the world. Generation with coal bed gas not only keeps the mine safe but also remits the situation of lacking power.

Requirements for coal bed gas（Within 1m to the intake valve of gas generator set）

Gas Temperature ≤40℃;

Pressure 3~20kpa, pressure changing rate≤1kpa/min;

H2 S≤200mg/Nm3;

If the CH4 covers less than 30%, the total content of CH4 and O2 should not less than 28%, the content of O2 should not less than 16%;

Moisture content≤40 g/Nm3;

Impurity Particle size≤5μm, impurity content≤30mg/Nm3

lf there are too much sulfur and ammonia in the gas, it will not only corrode the electrode of sparking plug heavily but also increase the acid value of engine oil which will corrode the parts inside of genets, easy to generate precipitate and increase the attrition corrosion to the engine.

Suitable to generator power with high and low concentration coal bed gas.
