摘　　要：为了探究炉膛传热性能,利用场协同理论对不同条件下的炉膛燃烧流场进行了分析。结果表明:在炉膛燃烧区壁面附近及中心部分区域,协同角α较小,而介于这两部分的大块区域,协同角α较大。协同角β大的区域占比相对较大。在整个燃烧区域,尤其是喷口附近,协同角γ较大,且分布比较均匀。协同角φ分布也比较均匀,大角度φ主要集中在壁面附近。在炉膛中心大部分区域以及炉膛顶部及折焰角处协同角θ较大,但是在喷口附近,协同角θ较小。The heat transfer performance under different conditions was analyzed by the field synergy theory to explore the combustion flow field in the furnace.The results showed that smaller synergy angleαwas found near the wall and in the center of combustion zone,while larger synergy angleαwas observed in the large zone between these two parts.The zone with larger synergy angleβaccounted for a relatively large fraction.In the whole combustion zone,especially near the nozzles,the distribution of larger angleγwas more uniform.The distribution of angleφwas also relatively uniform,and the large angleφwas concentrated near the wall.The larger synergy angleθwas distributed in most parts of the furnace center as well as the top and the furnace arch.But near the nozzles,the synergy angleθwas smaller.
