| 英文摘要 | The present paper has compared a group of furnace aerodynamic fields at different velocities of side secondary air (SSA) in a test model of 420t/h utility boiler, applying Horizontal Bias Combustion Pulverized Coal Burner with Side Secondary Air (HBC-SSA Burner). Experimental results show that, when the ram pressure ratio of side secondary air (SSA) to primary air (PA) (ρ2sν2s /ρ1ν12) is between 1.0-2.4, the furnace aerodynamic field only varies slightly. The relative rotational diameters(Φ／L) in the burner domain are moderate and the furnace is in good fullness. Whenρ2sν2s /ρ1ν12 is beyond 4, Φ／L is so large that the stream sweeps water-cooled wall and rotates strongly in the furnace. Therefore, slagging and high temperature corrosion of tube metal will be formed on the water-cooled wall in actual operation. This investigation provides the basis for the application of this new type burner. In addition, numerical simulations are conducted, and some defects in the numerical simulation are also pointed out and analyzed in this paper. |
