Physical Analysis of Volatilization Combustion during Coalfield Fire

摘要：

The physical models on the volatilization combustion were established in the light of its characteristics of coalfield fire area. The equations of mass exchange, momentum, diffusion and energy with the thermal and quality exchange and the chemical reaction and multi-composition flow were setup and analyzed by analytic method. The parameters of volatilization combustion speed, the content of the volatile component and the flame temperature were obtained at relatively still high temperature environment. Through results analysis, the flame temperature of the volatilization combustion of coal field fire area is the heat insulation temperature calculating in the light of low-beat value of the volatile component. It is concluded that, in actual coalfield fire area, the true temperature would be lower than that in the calculation because of the natural or forced convection.
