| Popis: | This paper presents the results of the numerical simulation of the methane-air combustion in the direct-flow burner. The construction of the burner was proposed by the Department of Thermal power plants MPEI for organization the staged combustion. the burners are designed for installation on boiler 300 MW TGMP-314 at thermal power plane in Moscow. The simulation of five modes of operation of the burner depending on the boiler load was carried out using modern packages of computational fluid dynamics ANSYS. The goal of this work is to investigate effects of replacement of existing vortex burners in previously described facilities with the direct-flow burners with organization of the new combustion process. As results after the simulation, the parameters of the numerical values of the turbulence parameters and the mass fractions of various substances for the gas-air flow in the boiler inlet plane was obtain. On the basis of the obtained results analysis of the proposed design of the burner was made. Numerical values of the parameters of the gas-air flow in the plane of the inlet to the boiler will be used later as input data for the numerical simulation of the boiler furnace. |
