350KW reliable operation coal gas engine(350GFW)
The coal gas engine brief:
300 series coal gas engines are driven by coal gas, firewood gas, blast furnace gas and coke-oven gas and so on. Nowadays in the use of one-off energy sources in the world, one obvious trend is developed that more combustible gas used than coal and oil gradually. That's because the pollution of coal and oil is seriously, and also the transport quantity is larger. For instance, the 80% of CO2 of cities come from the combustion of petrol products, and the main causation of greenhouse effect is the increase of CO2. Our country possesses abundant coal gas resources, and all the gas resources can be used by 300 series coal gas engines after it disposal. 300 series coal gas engines hold most widely development space.
According to especial working condition, many modifications have been introduced to improve the performance of the coal gas engine. There are characteristics in advanced performance, such as compact structure, reliable operation, pretty lay out, easy operation and maintenance.
Different types of stationary engine sets are available mainly, with frequency of 50Hz and 60Hz, can satisfy the customer 6.3kv/10.5kv exportation, for them, single power set running and multi-power sets parallel running are both ok.
