A problem on combustion of a methane–air mixture in a slot burner with an internal insert in mass transfer from the burner′s exterior wall to the environment has been solved. A mathematical formulation of the problem takes account of the dependence of the diffusion, thermal-conductivity, and heat-transfer coefficients on temperature, and also of the heat removal from the gas to the environment by convective and radiant heat transfer. A numerical investigation has been carried out in a one-dimensional mathematical formulation of the problem in dimensional variables. The boundary of existence of a stable high-temperature regime of combustion of the methane–air mixture has been determined as a function of the rate of feed of the gas, the environmental temperature, and the width of the flow area of the burner.
