燃气发电机组对燃气的要求：

Gas generator set's requirements for gas:

1、燃气发电机组对天然气的要求在距离机组燃气进气调压阀前1m内，①天然气压力100～300kPa（增压机）或50-300kPa（非增压机）；②天然气中甲烷体积含量不低于70%；③H2S≤20mg/Nm3；④杂质粒度＜5μm，杂质含量≤30mg/Nm3；

1. The requirements for natural gas in gas generator sets are within 1 meter before the gas inlet pressure regulating valve of the unit, with a natural gas pressure of 100-300 kPa (for turbochargers) or 50-300 kPa (for non turbochargers); ② The methane volume content in natural gas shall not be less than 70%; ③H2S≤20mg/Nm3； ④ Impurity particle size<5 μ m, impurity content ≤ 30mg/Nm3;

若可燃气体中含硫及氨成份较高，不仅会严重腐蚀火花塞电极，而且会使机油中酸值增加，腐蚀机组内部零件，同时易于生成沉淀物，增加对发动机的腐蚀和磨损。

If the combustible gas contains high levels of sulfur and ammonia, it will not only severely corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the unit, and easily generate sediment, increasing the corrosion and wear of the engine.

2、燃气发电机组对沼气的要求在距离机组燃气进气调压阀前1m内，①沼气温度≤40℃；②沼气压力3～10kPa，压力变化速率≤1kPa/min；③沼气中甲烷体积含量不低于40%，变化速率≤2%∕min；④H2S≤200mg/Nm3；⑤NH3≤20mg/Nm3；⑥杂质粒度≤5μm，杂质含量≤30mg/Nm3；⑦沼气中水份含量≤40g/Nm3。对于甲烷体积含量30～40%的沼气需要机组特殊配置，选另一型号的产品。

2. The requirements for biogas in gas generator sets are within 1 meter before the gas inlet pressure regulating valve of the unit, with ① biogas temperature ≤ 40 ℃; ② Biogas pressure is 3-10kPa, with a pressure change rate of ≤ 1kPa/min; ③ The methane volume content in biogas is not less than 40%, and the rate of change is ≤ 2%/min; ④H2S≤200mg/Nm3； ⑤NH3≤20mg/Nm3； ⑥ Impurity particle size ≤ 5 μ m, impurity content ≤ 30mg/Nm3; ⑦ The moisture content in biogas is ≤ 40g/Nm3. For biogas with a methane volume content of 30-40%, special configuration of the unit is required. Choose another model of product.

3、燃气发电机组对瓦斯的要求在距离机组燃气进气调压阀前1m内，①瓦斯温度≤40℃；②瓦斯压力3～10kPa，压力变化速率≤1kPa/min；③瓦斯中甲烷体积含量不低于9%，变化速率≤2%∕min；④对于甲烷体积含量小于30%的瓦斯，甲烷与氧气体积含量之和不低于28%，氧气体积含量不低于16％；⑤杂质粒度≤5μm，杂质含量≤30mg/Nm3。⑥硫化氢含量不大于200mg/m3。对于超出规定范围的气体需与厂商沟通，根据气体成份核实是否可行。

3. The gas generator set requires a gas temperature of ≤ 40 ℃ within 1m before the gas inlet pressure regulating valve of the unit; ② Gas pressure 3-10kPa, pressure change rate ≤ 1kPa/min; ③ The methane volume content in gas is not less than 9%, and the rate of change is ≤ 2%/min; ④ For gases with methane volume content less than 30%, the sum of methane and oxygen volume content shall not be less than 28%, and the oxygen volume content shall not be less than 16%; ⑤ Impurity particle size ≤ 5 μ m, impurity content ≤ 30mg/Nm3. ⑥ The hydrogen sulfide content shall not exceed 200mg/m3. For gases that exceed the specified range, it is necessary to communicate with the manufacturer and verify the feasibility based on the gas composition.

4、燃气发电机组对焦炉煤气的要求在距离机组燃气进气调压阀前1m内，①焦炉煤气温度≤40℃；②焦炉煤气压力3～10kPa，压力变化速率≤1kPa/min；③焦炉煤气中氢气体积含量≤60%；④H2S≤200mg/Nm3；⑤NH3≤20mg/Nm3；⑥焦油含量≤50mg/Nm3；⑦杂质粒度≤5μm，杂质含量≤30mg/Nm3；⑧焦炉煤气中水份含量≤40g/Nm3。
