　　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.

　　天然氣介紹

　　Introduction to Natural Gas

　　天然氣——主要成分是甲烷，含量達90%，燃燒產(chǎn)生的氮氧化物、碳氫化物和一氧化碳遠遠低于國家規(guī)定的排放標準，無粉塵污染；天然氣的熱轉(zhuǎn)化效率為65%，與石油液化氣相當，高于煤炭；按等熱值換算，天然氣的價格已經(jīng)低于煤炭，也遠遠低于石油。天然氣可用作民用、發(fā)電、化工原料和工業(yè)燃料等，對煤炭、石油進行有效替代。如可替代居民用煤制氣，替代煤炭和石油作為氮肥原料，替代石腦油作為乙烯原料，替代石油作為汽車發(fā)動機燃料等。

　　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是液化石油氣，LPG主要成分是丙烷。

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

　　CNG是壓縮天然氣，天然氣經(jīng)過壓縮到20MPa形成的高壓天然氣稱為壓縮天然氣（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是液化天然氣，天然氣經(jīng)過超低溫深冷到-162℃形成的液態(tài)天然氣稱為液化天然氣（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).

　　機組對天然氣的要求（在距離燃氣機組燃氣進氣閥1m內(nèi)）：

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

　?、?天然氣中CH4體積含量≥70%；

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

　　② 天然氣壓力80～200kpa，壓力變化率≤1kpa/min；

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

　?、?H2S≤20mg/Nm3；

　?、?H2S≤20mg/Nm3；

　?、?天然氣中水分含量≤40g/Nm3；

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

　?、?雜質(zhì)粒度≤5μm，雜質(zhì)含量≤30mg/Nm3。

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

　　如果可燃氣體中含硫及氨成分較高，不僅會嚴重腐蝕火花塞電極，而且會使機油中的酸值增加，腐蝕機組內(nèi)部零件。同時易于生成沉淀物，增加對發(fā)動機的磨損和腐蝕。

　　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.

　　適用場合：

　　Applicable occasions:

　?、?油田石油伴生氣發(fā)電；

　?、?Oil field associated gas power generation;

　?、?工業(yè)園區(qū)；

　?、?Industrial park;

　?、?石油加工化工廠；

　　③ Petroleum processing and chemical plants;

　?、?用天然氣發(fā)電作為備用電源；

　?、?Using natural gas to generate electricity as a backup power source;

　　⑤ 油井配套單機提供動力；

　?、?Oil well supporting single machine provides power;
