天然气发电机组是以天然气、LPG、LNG、油田伴生气等高热值气体为燃料的点火式气体机。在非增压机型的基础上增加了增压系统和中冷系统，冷却系统采用高低温循环分开的方式，高温循环冷却气缸、机体、气缸盖等高温部件，低温循环冷却增压后的燃气、空气以及油冷器。

　　Natural gas generator sets are ignition type gas engines that use high calorific value gases such as natural gas, LPG, LNG, and associated gas from oil fields as fuel. On the basis of non supercharged models, a supercharging system and an intercooler system have been added. The cooling system adopts a high and low temperature cycle separation method, with high temperature cycle cooling the cylinder, body, cylinder head and other high-temperature components, and low temperature cycle cooling the supercharged gas, air and oil cooler.

　　天然气介绍

　　Introduction to Natural Gas

　　天然气——主要成分是甲烷，含量达90%，燃烧产生的氮氧化物、碳氢化物和一氧化碳远远低于国家规定的排放标准，无粉尘污染；天然气的热转化效率为65%，与石油液化气相当，高于煤炭；按等热值换算，天然气的价格已经低于煤炭，也远远低于石油。天然气可用作民用、发电、化工原料和工业燃料等，对煤炭、石油进行有效替代。如可替代居民用煤制气，替代煤炭和石油作为氮肥原料，替代石脑油作为乙烯原料，替代石油作为汽车发动机燃料等。

　　Natural gas - the main component is methane, with a content of up to 90%. The nitrogen oxides, hydrocarbons, and carbon monoxide produced by combustion are far below the national emission standards, and there is no dust pollution; The thermal conversion efficiency of natural gas is 65%, which is comparable to liquefied petroleum gas and higher than coal; According to the equivalent calorific value conversion, the price of natural gas is already lower than that of coal and far lower than that of oil. Natural gas can be used as a civilian, power generation, chemical raw material, and industrial fuel, effectively replacing coal and oil. If it can replace residential coal to gas, replace coal and petroleum as nitrogen fertilizer raw materials, replace naphtha as ethylene raw material, replace petroleum as automotive engine fuel, etc.

　　LPG是液化石油气，LPG主要成分是丙烷。

　　LPG is liquefied petroleum gas, and its main component is propane.

　　CNG是压缩天然气，天然气经过压缩到20MPa形成的高压天然气称为压缩天然气（CNG）。

　　CNG is compressed natural gas, and the high-pressure natural gas formed by compressing natural gas to 20MPa is called compressed natural gas (CNG).

　　LNG是液化天然气，天然气经过超低温深冷到-162℃形成的液态天然气称为液化天然气（LNG）。

　　LNG is liquefied natural gas, and the liquid natural gas formed by ultra-low temperature deep cooling of natural gas to -162 ℃ is called liquefied natural gas (LNG).

　　机组对天然气的要求（在距离燃气机组燃气进气阀1m内）：

　　Requirements for natural gas by the unit (within 1m of the gas inlet valve of the gas unit):

　　① 天然气中CH4体积含量≥70%；

　　① The volume content of CH4 in natural gas is ≥ 70%;

　　② 天然气压力80～200kpa，压力变化率≤1kpa/min；

　　② Natural gas pressure is 80-200kpa, with a pressure change rate of ≤ 1kpa/min;

　　③ H2S≤20mg/Nm3；

　　③ H2S≤20mg/Nm3；

　　④ 天然气中水分含量≤40g/Nm3；

　　④ The moisture content in natural gas is ≤ 40g/Nm3;

　　⑤ 杂质粒度≤5μm，杂质含量≤30mg/Nm3。

　　⑤ Impurity particle size ≤ 5 μ m, impurity content ≤ 30mg/Nm3.

　　如果可燃气体中含硫及氨成分较高，不仅会严重腐蚀火花塞电极，而且会使机油中的酸值增加，腐蚀机组内部零件。同时易于生成沉淀物，增加对发动机的磨损和腐蚀。

　　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 and corrode the internal components of the unit. At the same time, it is easy to generate sediment, which increases the wear and corrosion of the engine.
