Natural Gas Generator Set
Natural gas which mainly composed by CH4.(It is about 90% of total gas).the displacement of nitrogen oxide,  HCHydrogen Carbonide and  carbonic oxide from burning are much lower than the state standards and without dust pollution. Thermal efficiency of coversion is 65%,which is same to the LPG and higher than Coal.Calculated on the same calorific value,the price of natural gas is lower than the price of coal and petroleum. Natural gas can be used by home application, Electricity generation,industrial chemical and industrial fuel and so is a good substitute of coal and petroleum. It can instead of civil coal gas,it can be used as nitrogenous fertilizer instead of coal and petroleum, it can be used as ethylene of naphtha,it also can be used as the car engine fuel instead of petruoleum.
Requirement for natural gas:
1.Within 1m from pressure regulating valve of gas intake.
2.the ratio of CH4. in natural gas not less than 70%.
3.Pressure of natural gas 80-200kpa,Rate of pressure change≤1kpa/min
4. H2S≤200mg/Nm3
5.Moisture content≤40g/N m3
6.Impurity particle size≤5μm, impurity content≤30g/N m3
7. If fuel gas contains higher quantity of sulfur and ammonia ,it will not only corrode the pole 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.

The key and premise of generating gas is that biomass is gasified and generated gas.according to different crafts,there are many kinds of equipments to generate biomass gas. The higher the heat value of biomass gas the less impurity to generate more electric power. It will not only increase the efficiency of generating gas,but also reduce the damage to generator equipment by impurity.

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
Within 1m to the intake valve of gas generator set
1.     Gas temperature≤40°C
2.     Pressure 3-20kpa, pressure changing rate≤1kpa/min
3.     H2S≤200mg/Nm3
4.     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%.
5.     Moisture content≤40g/N m3
6.     Impurity particle size≤5μm, impurity content≤30mg/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.

Coal Gas Generator Set
There are many methods to produce coal gas, such as coke oven gas, coal producer gas, semi-coke gas, water coal gas, oil coal gas, oil coal gas, blast-furnace and cracking coal gas etc. The main compositions are CO, H2, N3, CO2 and so on.
The producing method of coke oven gas is as below: raw coal is crushed and washed, then put them into furnace with different coal mixed together in different ratio, after that the coal in a limited conditions which is been heated and disintegrated in a isolate air condition. It will produce coal gas and coal tar with high temperature.
Gas Composition of Coke Oven Gas:
H2: 50-60  
O2: 0.4-0.6
CH4: 22-26
CmHn: 2.2-2.6  
CO: 2-3
N2: 2.24        
CO2: 2.2
After through conventional cooling, desulfurization, detar and dehydration treatments, coke oven gas will generate power with internal combustion generator. The power will be as self-provided power for coke oven factory and can be connected to national grid, which avoid coal gas emptying.
The genset is for steel plant and coke-oven plant.
The producing method of coal producer gas is as below: after lighting the coal, a great amount of CO is produced with incomplete combustion by limiting air in the bottom of furnace. The main compositions are CO, CO2 and N2.
The producing method of water coal gas is as below: after lighting the coal, make coal burn completely by blowing enough air from the bottom of furnace, and then stop blower and inject water vapor from the bottom and the top of furnace, a great amount of H2 and CO are produced when the water vapor combines with hot coal, and then it forms water coal gas when mixing with N2 in the air and the left water vapor.  
Semi-coke is made from smokeless coal in low temperature and dry distillation klin, its technology is similar to coal gas gasifier, just the output product is different with different heating temperature. In the producing process of Semi-coke, a great amount of exhaust gas is produced from 1T semi-coke in low temperature and dry distillation klin, and the heat value of coal gas is about 1900kcal, which can meet the requirement of generating power.
The main composition of coal gas which produced by current internal heating type of semi-coke furnace is N2 (about 50%), others are H2, CO, CO2 and CH4. Because there are many useless compositions in semi-coke gas, and the heat value is low (1800-2000kcal), all these limit its range of application and a great quantity of semi-coke gas are evacuated or burned
Requirements for Coal Gas Genset
Within 1m from gas intake valve
1.     Coal gas temperature ≤40oC;
2.     Pressure of coal producer gas: 3-20kpa, rate of pressure change≤1kpa/min;
3.     H2S≤200mg/Nm3;
4.     NH3≤20mg/Nm3;
5.     Tar content≤50mg/Nm3
6.     Impurity particle size≤5μm, Impurity content≤30mg/Nm3;
7.     Moisture content≤40g/Nm3;
8.     Gas heat value≥4.2 mj/Nm3
If fuel gas contains higher quantity of sulfur and ammonia, it not only corrodes the pole of spark plug seriously, but also increases the acid value, which corrodes internal parts of genset and corrodes the genset with precipitates.
