Abstract
Results from theoretical investigations into transfer processes during the combustion of anthracite culm in a circulating fluidized bed furnace are presented. A method is described according to which hot air is separately admitted into the furnace: the primary air, to under the fluidized-bed grate, and the secondary air, to over its upper boundary. Calculation results together with their discussion are presented.
