The experimental study on aerodynamic field in composite burner of rich/lean pulverized coal separated in spout of the blunt body has been carried out. The standard dual equation turbulence model is used for calculating the gas-phase field
and the triangle grid being used for establishing the grid system. Through organic combination of the burner’s inner space with the spout jet inside the Furnace
an integrated calculation has been performed
obtaining aerodynamic behavior in the whole gas flow field under conditions of innerpositioned blunt body and outer-positioned blunt body respectively. After analysis and comparison
it is found that the rich/lean pulverized coal burner with inner-positioned blunt body has better effectivencess in application.
