Aug 27, 2021 · Combustion is a vital and one of the initial processes in the functioning of steam boilers. Various fuels are ignited in solid fuel boilers that require proper combustion to generate steam and avoid greenhouse emissions from unburned fuels. Fluidized bed combustion is a technique that effectively burns the fuels in solid fuel boilers.
