Coal-Fired Industrial Boiler Inspection Guide

Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash. In contrast, a stoker-fired boiler emits only 3.0 to 50 percent of the coal ash with the flue gas. In addition, the particulate matter generated by stoker boilers tends to be much coarser than the ash from pulverized-coal-fired boilers, and it generally contains considerably more carbon.

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 ).
