City sewage water treatment, garbage field, alcohol production, citric acid production, amylum production, paper making, breed aquatics can produce 11 billion m3 marsh gas every year, can this can generator power, reduce resource comsumption, waste. This can give economy benefit, and protect environment.
Regeneratable source low of People’s Republic of China and Regeneratable source power generation cost apportion way give clear provision on power generation. In August 2007, China government transmit the Energy saving power generation measure.
The unit optimized the design according to marsh gas specification, is very stable.
Requirement on gas:
1. Gas cannot excess 40? in 1 meter from inlet valve;
2. Pressure 3~10KPa, pressure change rate ≤1KPa/Min;
3. Firedamp cannot less than 40%, change rate ≤2%;
4. H2S≤200mg, NH3≤20mg/Nm, impurity granularity≤5μm, impurity≤30mg/Nm;
5. Water is not higher than 40g/Nm.
