Product Description

Coal-fired Power Plant


Coal is the traditional fuel of power plant. There is abundant storage of coal over the world, and developing cost is quite low. With the characteristic of higher heating value and stable combustion, coal is the main fuel for power plant. Coal fired power plants, till now, are still the major electricity source for most of countries in the world, playing an important role in national economy and social production of each country.

According to the different coal ranks and other factors, coal can be divided into many types. The following data shall be evaluated for the coal used in thermal power plant, and these data have a significant impact on entire power plant system configuration and efficiency, etc.

Different coal should adopt different furnace combustion method, so as to acquire stable and sufficient combustion, improve efficiency of boiler, whole power plant, and suppress & reduce poisonous gas emission (such as SOx, NOx etc). Normally, boiler can be divided into following types: stoker boiler (Clockwise, counter-clockwise, spreader stoker, reciprocating grate, etc.), bubbling bed boiler, CFB boiler, pulverized coal boiler etc., among which, CFB boiler, gifted by the feature of wide adaptability of different coal, sufficient combustion, and environment friendly (achieve the desulfurization inside furnace and reduce the emission of NOx with low temperature combustion), is widely adopted in the small & medium sized power plants in recent years, which has brought great economic and social benefits.
