Pulverized Coal Boiler - an overview | ScienceDirect Topics

A typical pulverized coal boiler consists of (1) the furnace, which is the lower boiler part, where the burners and the firing system are installed and where the combustion takes place and (2) the convective section, where the convective heat exchanger surfaces are installed. The boiler membrane walls have usually the function of the boiler evaporator.

[PDF] CO-COMBUSTION OF COAL AND OIL SHALE BLENDS IN

Coal co-firing experiments were conducted in a 250 MW oil shale fired circulating fluidized bed combustion (CFBC) boiler. The objective of the experiments was to test whether adding coal to oil shale would allow the use of the latter with lower heating value. Bituminous coal was mixed with oil shale and fed into the boiler via existing fuel feeding ports.
