Rational choice of PC granularity is of an important measure to decrease comprehensive cost of generating power in an electric power plant

Focusing on the objective condition that Taicang generating power Co. Ltd has been in short supply of burning coal, which has made the actual quality of combustion coal put is not accordance with the one designed for it. Hence, the burning feature tests of combusting northeast coal type were done, the results showed that different kinks of coal need to choose proper and right PC granularity in order to decrease the volume of fly ash, promote boiler's efficiency, reduce loss of burning coal, meanwhile minimize the general cost of generating power.
