1. Natural gas generating set requirements for natural gas
The natural gas pressure is 100 ~ 300kPa (turbocharger) or 50-300kPa (non turbocharger) in the distance of gas intake pressure valve in the distance of 1m; (2) the volume content of methane in natural gas is not less than 70%; (3) H2S < < 20mg/Nm3 >; impurity particle size < 5 m and impurity content less than 30mg/Nm3;
2. Biogas requirements for biogas generating units
In 1m, the methane temperature is less than 40 C in front of the gas inlet regulating valve, and the methane pressure is 3 ~ 10kPa, the pressure change rate is less than 1kPa/min, and the methane volume content is not less than 40%, the change rate is less than 2% / min; (4) H2S < 200mg/Nm3; (5) NH3 < 20mg/Nm3; 6. The impurity particle size is less than 5 micron, the impurity content is less than 30mg/Nm3; and the content of water content in the biogas is less than 40g/Nm3. For methane content of 30 to 40% biogas, we need special configuration of the unit and choose another product.
3. Gas generating set requirements for gas
In 1m, the gas temperature is less than 40 C in front of the gas inlet regulating valve, and the gas pressure is 3 ~ 10kPa, the pressure change rate is less than 1kPa/min; the methane volume content in gas is not less than 9%, the change rate is less than 2% / min; (4) for methane volume content less than 30%, the volume content of methane and oxygen is not less than 28%, and the volume content of oxygen is not less than 16%; besides, the particle size is not less than 16%; 5 Less than 5 m, the impurity content is less than 30mg/Nm3. The hydrogen sulfide content not greater than 200mg/m3. For the gas beyond the specified range, it is necessary to communicate with the manufacturer and verify whether it is feasible according to the gas composition.
4, the requirement of coke oven gas generator set to coke oven gas.
The coke oven gas temperature is less than 40 C in the distance of the gas inlet pressure valve of the unit, (1) the coke oven gas temperature is less than 40 C, the pressure of coke oven gas is 3 ~ 10kPa, the pressure change rate is less than 1kPa/min, and the volume content of hydrogen is less than 60% in the coke oven gas; (4) H2S < 200mg/Nm3; (5) NH3 < 20mg/Nm3; (6) coke content is less than 50mg/ Nm3; the impurity size is less than 5 mu m, impurity content is less than 30mg/Nm3; the moisture content of coke oven gas is less than 40g/Nm 3.
