Study of thermal-flow processes in ash cooler cooperating with CFB boiler Thermal-flow process. Introduction >The basic element of a conventional power plant is a boiler where chemical energy of fossil fuels (hard coal, lignite) is converted into a heat. As a result of combustion processes occurring in the boiler, a slag is produced.

2019-8-12 · Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant
