Pulverized coal-fired boiler - Wikipedia

2019-8-30 · A pulverized coal-fired 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.

Improving the Efficiency of Power Plants Firing High

Unfortunately, plants that utilize high-moisture coal pay a substantial price in efficiency. When such coals are burned in utility boilers, about 7% of the fuel heat input is used to evaporate and superheat the moisture in the fuel. Most of this lost heat can be attributed to the energy needed to evaporate the moisture in the fuel.
