1. Introduction. Coalfired power plants account for more than 70% of the total power generation capacity in China. This largescale coal consumption results in severe CO 2 emissions. China has been ranked No. 1 in CO 2 emissions since 2009. Thus, plans have been made to reduce CO 2 emission by 55%60% by 2020 under different macrocontrol measures of the state.

A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse.

A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
