Numerical analysis of the process of combustion and gasification of the polydisperse coke residue of high-ash coal under pressure in a fluidized bed

Abstract

A numerical analysis of the process of “wet” gasification of high-ash coal under pressure in a low-temperature fluidized bed has been performed. The applicability of the previously developed computational model, algorithm, and program for the case under consideration has been noted. The presence of “hot spots” (short-time local heatings) at different points of the bed has been confirmed.
