| 中文摘要: |
| 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 angle α was found near the wall and in the center of combustion zone, while larger synergy angle α was observed in the large zone between these two parts. The zone with larger synergy angle β accounted for a relatively large fraction. In the whole combustion zone, especially near the nozzles, the distribution of larger angle γ was more uniform. The distribution of angle φ was also relatively uniform, and the large angle φ was concentrated near the wall. The larger synergy angle θ was distributed in most parts of the furnace center as well as the top and the furnace arch. But near the nozzles, the synergy angle θ was smaller. |
