We have developed a generalized volume-averaged model 
of filtration combustion of gases taking into account the spatial 
inhomogeneity of a porous medium and the change in porosity due to 
the heterogeneous chemical processes. Adequate program codes have 
been realized. The calculations perfomed have shown that the gasification 
rate in a continuous reactor is almost proportional to the oxidizer 
flow rate and depends on the degree and character of inhomogeneity. 
It has been found that the CO content at the outlet depends on the 
degree of inhomogeneity.
