Experimental Study of the Combustion Characteristics of a 1025 t/h "W" Flame Boiler

介绍了英国MBEL设计生产的菏泽"W"火焰锅炉的燃烧系统设计特点及燃烧特性;结合调试实际对其燃烧器配风、燃料的燃尽、NOx及SO2的排放等特性加以论述分析;并针对锅炉的配风平行流场后期混合差、下炉膛卫燃带结焦、NOx排放量偏高等问题进行了分析与探讨,提出了初步的改进设想。

Presented are the design features and combustion characteristics of a W-flame boiler designed and manufactured by British MBEL Co. and installed at Heze Power Plant. In connection with the commissioning test results expounded and analyzed am the air distribution of burners, the characteristics of fuel burn-out and NOx and SO2 emissions. In addition, there existed a whole range of problems, such as the poor mixing of combustion-air distribution in a parallel-flow field at a later stage, the slag formation on a lower furnace refractory-belt, and the excessive amount of NOx emissions. To deal with these problems, the authors have made some preliminary recommendations to alleviate them.
