Pulverized coal-fired boiler - Wikipedia

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.

In the 1960s, the U.S. Government initiated studies to determine if coal was feasible as a gas turbine fuel. In these tests, coal was pulverized and mixed with various liquids prior to being fired in a gas turbine combustor. The result of these tests was that gas turbines are not capable of directly combusting pulverized or slurried coal for electrical production.
