Combustion System - an overview | ScienceDirect Topics

Combustion systems include the fluidized-bed furnace fire-grate furnace rotary kiln furnace and vortex combustion furnace (JSME 1996). Fire-grate furnaces can be divided into upflow and downflow systems. In an upflow system the gas generated by thermal decomposition of biomass in a fire grate goes upwards to be burned.
