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.
Plant design and technology. Pulverised coal firing power plant is a well proven technology for power generation from coal. The coal is ground, or pulverised, into a fine power to sizes less than 100 μm and is fed with primary combustion air into a boiler through burners where it is burnt to release heat energy in the furnace. It currently ...
