Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

A Dry Sorbent Injection (DSI) system is, as the name implies, a dry process in which a sorbent is pneumatically injected either directly into a coal-fired boiler or into ducting downstream of where the coal is combusted and exhaust (flue) gas is produced. This discussion will focus on the latter, more common, implementation of DSI.

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 furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain, mixed with air and burned in the flu
