INFLUENCE OF THE STEFAN FLOW ON HEAT TRANSFER IN THE SYSTEM "GAS–SOLID PARTICLE" IN THERMOCHEMICAL CONVERSION OF A SOLID FUEL

Recommendations are presented on calculating interphase heat transfer in gas-disperse systems of plants for thermochemical conversion of ground solid fuel. An analysis is made of the infl uence of the gas release of fuel particles on the heat transfer during their heating. It is shown that in the processes of thermal treatment of oil shales, the presence of gas release reduces substantially the intensity of interphase heat transfer compared to the heat transfer in the absence of thermochemical decomposition of the solid phase.
