炉膛口

An analytical model was built up on the jet deflection in the crossflow by applying the theorem of momentum, which takes full account of mixing between the upstream fluid and burner jet, and of the total pressure difference between the two sides of the jets. Through analysis of this model, experimental study and numerical simulation, effects of the nozzle spacing ratio, width of the furnace corner, width of the nozzle and imaginary circle diameter on the aerodynamic field in the furnace were obtained.
