filtration combustion, solid fuel, thermal structure, modelingAbstract
A two-temperature mathematical model is proposed for the stationary process of filtration combustion, which takes into account the finite size of the reactor and the dependence of heat capacities on temperature and phase composition. The model describes the gasification of solid fuel in the filtration regime. The results of calculations for the gasification of a mixture of carbon with an inert material are presented. The range of values of the content of the combustible component is determined, in which neither the normal nor the inverse thermal structure of the combustion wave is realized. The combustion temperature limit is shown in the entire range of the combustible component fraction.
