| This thesis reviewed systematically the development of numerical simulation for oxy - fuel combustion and turbulent combustion in combustion space of glass melting furnaces, and established three-dimensional mathematical model which is very practical in oil fired oxy -fuel unit glass furnaces on the base of theory of glass melting furnaces and industrial application. The model consisted of gas turbulent flows and heat transfer sub-model and spray combustion sub-model. The former includes continuity equation, momentum equation, turbulence equation and energy equation and were solved by SIMPLE and FEM scheme, the later makes use of the PSIC method.The flow field and temperature distribution of combustion space in oil fired oxy-fuel glass furnaces(9 OOOt/y) were studied in this paper. It was concluded that the oxy-fuel combustion temperature distribution of combustion space could be described well by three-dimensional model which would apply widely.
