500kw Coal Gas Generator Set for power plant
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.
This project is an ideal solution for regions where there are have cheap coal and shortage of electricity and using HFO or diesel making electricity.
In consideration of the above mentioned particulars, the feasibility of such Power station will save a lot money if some factory now using LPG or HFO to power their factroy.
The technology of producing power by gasification of coal is easy to operate, simple and economical in maintenances and service, has no high pressure steam, no turbines and is easy to start up and run the standard combustion generator.
The power station requires a small land area to operate. It is environmental-friendly, simple to install. These will in turn produce very low cost valuable electric power energy.
