【Abstract】 The technical modification of a primary air reverse tangential flow based was conducted of the tangentially fired boiler of a Chinese made 300 MW unit based on imported technology. The results of a cold state model test and numerical simulation indicate that the implementation of a primary air reverse flow technology on the above cited boiler can improve the in furnace aerodynamic field and solve various furnace fire side problems. In addition, it can also effectively reduce the residual rotation magnitude at the horizontal flue inlet.更多还原
