Secondary air tuyere: aluminum alloy shutter, the surface was electro-sprayed by epoxy resin. 补风口:采用铝合金百叶窗,表面环氧树脂喷涂。
As the inner secondary air swirling intensity increases, the recirculation zone size increases; But as the outer secondary air swirling intensity increases, the width of recirculation zone increases and the length decreases. The swirling intensity increases after the installation of the expanding tuyere. 内二次风旋流强度增大,回流区尺寸增大,外二次风旋流强度增大,回流区宽度增大而长度减小,加装扩口后燃烧器旋流强度增大,并随着扩口角度增加,扩展角增大。
