On simulation of transfer processes in the freeboard region of a steam-generator furnace with a circulating fluidized bed

A semiempirical, stationary, two-zone model of transfer processes in the freeboard region of a reactor with a circulating boiling layer has been constructed. The features of the aerodynamics, heat and mass transfer, and combustion of anthracite culm in the core and near-wall ring region of a flow in a KFS-0.2 pilot plant have been investigated in detail. __________ Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 79, No. 1, pp. 20–28, January–February, 2006.
