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.

The US DOE performed an assessment of the cost and performance for pulverized coal combustion (PC), IGCC, and NGCC, all with and without CO 2 capture and sequestration assuming that the plants used current technologies (US Department of Energy, 2013c). The coal used in this study was an Illinois #6 bituminous coal and the power plants, 550 MW ...

Coal utilization - Coal utilization - Coal combustion: The most common and important use of coal is in combustion, in which heat is generated to produce steam, which in turn powers the turbines that produce electricity. Combustion for electricity generation by utilities is the end use for 86 percent of the coal mined in the United States.

An experimental study of the nitric oxide emission from pulverized blended coal flames as a function of blending mass ratio is presented. Coals of three ranks (anthracite, bituminous, and lignite), and of the same rank (bituminous), but of different origin (Oklahoma and Wyoming mines), were used as fuels.

Subcritical units have efficiencies of between 33% and 37%; i.e. between 33% and 37% of the energy in the coal is converted into electricity. In the late 1960s, supercritical combustion technology was commercialized, after advances in materials technology made it possible to build boilers that could operate at higher pressures.
