A numerical method for calculating the processes of co-combustion of coal-water and pulverized coal fuel has been developed. The effect of operating parameters on the processes occurring in the combustion chamber at co-combustion of coal-water and pulverized coal fuel has been studied. It is shown that redistribution of air between two stages of the burner affects significantly the temperature distribution in the volume of combustion chamber. Based on the study, it is shown that the addition of microground coal ensures stable combustion of coal-water fuel at combined burning of these two fuels in a flow reactor.
