Markus Hurskainen, Pasi Vainikka, in Fuel Flexible Energy Generation, 2016. 7.2.3.1 General. Pulverised coal (PC) combustion is the most widely used technology for utility-scale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace.

delivering 500-1000 MW of electrical power. A 1000 MW pulverized coal fired power plant emits between 6-8 Mt/y of CO2, an oil fired single cycle power plant about two thirds of that, and a natural gas combined cycle power plant about one half of that. Second, several industrial processes produce highly concentrated streams of CO2 as a byproduct.

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.
Pulverized coal-fired units, which can cofire biomass, tend to be large. They often have a tower construction. This means that all heat transfer surfaces are placed on top of each other, with no backpass. The benefits of coal-fired units are reliability and proven technology. The drawback is their fuel. Coal generates a large amount of CO 2.
