Coal Mine/Bed Generator Set
Coal mine/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°C to 750°C.
explosive power will be biggest if concentration is 9.5%. it will burn but not explode if concentration larger than 16%.
It was generated by coal or rotten plants and exist in two states:absorbing & dissociate. Generation with coal mine/bed gas
not only keep the mine safe but also relieve the situation of lacking power.
Requirement for Coal mine/bed gas
1. Within 1m to the intake valve of gas generator set
2. Gas temperature≤40°C
3. Pressure 3-20kpa,pressure changing rate≤1kpa/min
4. H2S≤200mg/Nm³
5. If the CH4 content less than 30%,the total content of CH4 and O2 should not less than 28%,
the content of O2 should not less than 16%.
6. Moisture content≤40g/N m³
7. Impurity particle size≤5μm, impurity content≤30g/N m³
If there are too much sulfur and ammonia in the gas, it will not only corrode the electrode of sparking plug seriously
but also increase the acid value of engine oil which will corrode the parts inside of genset,
easy to generation sediment and increase the attrition corrosion to the engine.
