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.
