The problem of the stability of combustion of a polydisperse suspension of coal dust in a methane-air mixture within the burner with a heat recovery is solved. The boundary of a stable combustion of coal-methane-air mixture is determined in relation to the composition and feed rate of the mixture at the burner inlet. It is shown that the stability of combustion of coal-methane-air mixture is affected by the ratio between the mass content of the inert and reacting particles and the ratio between finely dispersed and coarsely dispersed fractions of dust particles. The mixture containing a high percentage of the mass of finely dispersed fraction burns steadily in a wide range of the feed rates of mixture at the burner inlet. The presence of inert particles leads to the reduction in the mixture feed rate range within which the stable combustion of carbon-methaneair mixture is possible.
Keywords: coal-methane-air mixture, polydisperse coal dust, slot burner, combustion stability.
