They use both undergrate and overfire air to burn fuel located on a grate. Different designs for stokers are described in Sect. 2.2.1. The PC-fired boilers are generally large field-erected units such as the one shown in Fig. 2.9. During operation, finely ground coal is mixed with primary combustion air and fed to the burner or burners where it

Cyclone boilers burn crushed (but not pulverized) coal in large (e.g., 10-ft dia.) cyclone barrels and send hot (e.g., 3200–3550°F or 1760–1950°C) gases into the furnace and then convective pass. Cyclone boilers are designed to maximize the production of slag from the inorganic constituents in fuel; inorganics are managed in this manner.
