1、燃氣發電機組對自然氣的請求在間隔機組燃氣進氣調壓閥前1m內,①自然氣壓力100~300kPa(增壓機)或50-300kPa(非增壓機);②自然氣中甲烷體積含量不低于70%;③H2S≤20mg/Nm3;④雜質粒度<5μm,雜質含量≤30mg/Nm3;

1. Requests for natural gas from gas generating units are within 1 m before the gas intake pressure regulating valve of the spacer units, i.e. 100-300 kPa (supercharger) or 50-300 kPa (non-supercharger); (ii) methane volume content in natural gas is not less than 70%; (iii) H2S is less than 20 mg/Nm3; (iv) impurity size is less than 5 micron and impurity content is less than 30 mg/Nm3;

若可燃氣體中含硫及氨成份較高,不只會嚴重腐蝕火花塞電極,而且會使機油中酸值增加,腐蝕機組內部零件,同時易于生成沉淀物,增加對發起機的腐蝕和磨損。

If the content of sulfur and ammonia in combustible gas is high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the oil, corrode the internal parts of the unit, and easily generate precipitates, which will increase the corrosion and wear of the generator.

D88尊龙2、燃氣發電機組對沼氣的請求在間隔機組燃氣進氣調壓閥前1m內,①沼氣溫度≤40℃;②沼氣壓力3~10kPa,壓力變化速率≤1kPa/min;③沼氣中甲烷體積含量不低于40%,變化速率≤2%∕min;④H2S≤200mg/Nm3;⑤NH3≤20mg/Nm3;⑥雜質粒度≤5μm,雜質含量≤30mg/Nm3;⑦沼氣中水份含量≤40g/Nm3。關于甲烷體積含量30~40%的沼氣需求機組特殊配置,選另一型號的產品。

D88尊龙2. Requests for biogas from gas-fired generating units are within 1 m before the gas intake pressure regulating valve of the spacer units. Firstly, the temperature of biogas is less than 40 C; secondly, the pressure change rate is less than 1 kPa/min when the pressure of biogas is 3-10 kPa; thirdly, the volume content of methane in biogas is not less than 40%, and the change rate is less than 2%min; fourthly, H2S is less than 200 mg/Nm3; NH3 is less than 20 mg/Nm3; _the particle size of impurities is less than 5 micron, and the impurities content is less than 30 mg/Nm3; The water content is less than 40g/Nm3. About the special configuration of methane generating units with 30-40% methane volume, another type of product is selected.

若可燃氣體中含硫及氨成份較高,不只會嚴重腐蝕火花塞電極,而且會使機油中酸值增加,腐蝕機組內部零件,同時易于生成沉淀物,增加對發起機的腐蝕和磨損。

If the content of sulfur and ammonia in combustible gas is high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the oil, corrode the internal parts of the unit, and easily generate precipitates, which will increase the corrosion and wear of the generator.

D88尊龙3、燃氣發電機組對瓦斯的請求在間隔機組燃氣進氣調壓閥前1m內,①瓦斯溫度≤40℃;②瓦斯壓力3~10kPa,壓力變化速率≤1kPa/min;③瓦斯中甲烷體積含量不低于9%,變化速率≤2%∕min;④關于甲烷體積含量小于30%的瓦斯,甲烷與氧氣體積含量之和不低于28%,氧氣體積含量不低于16%;⑤雜質粒度≤5μm,雜質含量≤30mg/Nm3。⑥硫化氫含量不大于200mg/m3。關于超出規則范圍的氣體需與廠商溝通,依據氣體成份核實能否可行。

3. Gas requests of gas generating units are within 1 m before the gas intake pressure regulating valve of the spacer units, i.e. gas temperature is less than 40 C; gas pressure is 3-10 kPa, and pressure change rate is less than 1 kPa/min; gas volume content is not less than 9%, change rate is less than 2%min; and gas volume content is less than 30%, gas volume content of methane and oxygen is not less than 28%, oxygen gas. The volume content is not less than 16%. _The particle size of impurities is less than 5 microns and the impurity content is less than 30 mg/Nm3. The content of hydrogen sulfide is not more than 200 mg/m3. For gases beyond the scope of the rules, it is necessary to communicate with the manufacturer and verify the feasibility according to the composition of the gases.

4、燃氣發電機組對焦爐煤氣的請求在間隔機組燃氣進氣調壓閥前1m內,①焦爐煤氣溫度≤40℃;②焦爐煤氣壓力3~10kPa,壓力變化速率≤1kPa/min;③焦爐煤氣中氫氣體積含量≤60%;④H2S≤200mg/Nm3;⑤NH3≤20mg/Nm3;⑥焦油含量≤50mg/Nm3;⑦雜質粒度≤5μm,雜質含量≤30mg/Nm3;⑧焦爐煤氣中水份含量≤40g/Nm3。

4. Requests for coke oven gas from gas generating units are within 1 m before the gas intake pressure regulating valve of the spacer units, i.e. coke oven gas temperature is less than 40;(ii) coke oven gas pressure is 3-10 kPa, pressure change rate is less than 1 kPa/min; (ii) hydrogen gas volume content in coke oven gas is less than 60%; (iv) H2S is less than 200 mg/Nm3; (iv) NH3 is less than 20 mg/Nm3; (iv) tar content is less than 50 mg/Nm3; (iv) impurity particle size is less than 5 um, impurity content is less than 30 mg. / Nm3; _Water content in coke oven gas is less than 40g/Nm3.
