本文采用数值计算的方法对液排渣粉煤旋风燃烧器内的流场进行了模拟。
This paper simulates the flow field of the slag swirl burner by the numerical calculation methods.
简单环形挡渣板也能产生环形回流区，在旋风燃烧室设计中可取代锥形缩口挡渣板。
Annular reverse flow zone can be found too in the combustor with the flat-straight slag baffle.
在工业上应用十分广泛，如在射流技术、燃烧技术、气力输送、旋风分离及水力浮选等方面均应用了螺旋流。
Swirling flow is widely used in industry, such as in jet technology, combustion technology, pneumatic transportation, cyclone separator, hydraulic flotation and so on.
