一、前言旋流被广泛地应用于燃烧技术中,尤其是在燃烧粉煤或煤水浆时,燃烧装置的合理结构,尤其是调风器所形成的流场特性,即速度场、压力场等的变化规律,对促进燃料和空气的混合,高温烟气的回流及稳定燃烧等都有着重要的意义。而在燃用煤水浆时,由 First, the preface Swirl is widely used in combustion technology, especially in the combustion of pulverized coal or coal slurry, the rational structure of the combustion device, especially the flow regulator formed by the flow field characteristics, namely the velocity field, the pressure field And other changes in law, to promote the mixing of fuel and air, high temperature flue gas return and stable combustion are all of great significance. When burning coal water slurry, from
