As the world famous power corporation,NIGM (North International General Machinery Holdings Limited),taking the lead in bringing in high power Fuel engine and generator set,and also successfully proceeded the localization upgrades and modification.,our engine power can from 200kw—4000kw,the fuel can meet Biomass gas/mashgas/biogas/coalbed gas/Natural gas and so on. Electrical efficiency can up 38-45%.can continue running 7500-8000hours.our product h***e been widely use in Chinese oil field and the CNOOC platform. Power plant, distributed energy and so on. Product st below:
(1) high power gas machine multipoint injection
(2)High power engine matching technology:
(3) high power gas machine air-fuel ratio, speed load control technology:
(4) the high power engine knock detection, fire detection and monitoring technology
(5) the high power engine oil mist detector, such as security protection technology
(6) the self-cleaning metal filter oil filter, will be able to realize the automatic cleaning, need not change filter, which can guarantee the engine oil filtration requirements, filter using live longer, reduce the cost and maintain the intensity of labor
(7) key parts such as bearings, piston, ignition system USES the international first-class products, to meet the engine performance and high reliability requirements.
Besides,our company also provide NIGM-26/32 container type power plant.This kind of products h***e been widely used in the CNOOC platform.
Gas source including:Natural Gas,Coal Mine Gas, Biomass Gas,Methane and other various kinds of combustible gas.
