A comparative analysis of equilibrium and nonequilibrium 
models for calculation of the rates of phase transitions (evaporation 
and condensation) of pyrolysis products and the influence of convective 
heat and mass exchange with inert ash particles and the gas flow in 
pyrolysis of single particles of high-ash coals in the operation of 
technological units with a circulating fluidized bed under pressure 
is made.
