The authors have presented results of experimental and theoretical studies on combustion and gasification of mixtures of various kinds of solid fuel (wood pellets, wood chips) with the inert (spheres of alumina, crushed chamotte brick) in a vertical reactor operating on the principle of superadiabatic filtration combustion. Experimental data (temperature and the wave velocity) have been obtained for different concentrations of the fuel in the inert, kinds of fuel, and flow rates of the air. To determine the localization of a reaction zone and the thermal-wave velocity, use was made of the data of infrared-imaging measurements. A physicochemical model of filtration combustion of a solid fuel with an inert filler in a superradiative-wave regime has been created. Calculations of the thermodynamic characteristics of combustion and the equilibrium composition of combustion products have been done for a wide range of mixtures of wood and air. Calculated dependences of the temperature distributions and the velocity of the combustion front and the thermal wave have been obtained for different concentrations of the wood in the inert and flow rates of the air.
