分析了 W火焰锅炉的负荷特性 ,指出燃烧无烟煤存在的问题 (尤其是积灰和结焦 )较严重 ,主要原因是炉膛热负荷较大 ,受炉膛内空气动力场的影响以及一、二次风配比不合理。提出了解决问题的关键在于提高调整的精度 ,合理改进运行方式 ,以及采用先进的测量、监视手段 ,改善锅炉的变负荷、变煤种适应性 Analysis of the load characteristics of the W flame boiler, pointed out that the problems of burning anthracite (especially fouling and coking) is more serious, mainly due to the large furnace heat load, by the aerodynamic field in the furnace and the primary and secondary air with Than unreasonable. Put forward the key to solve the problem is to improve the accuracy of adjustment, reasonable operation mode, as well as the use of advanced measurement and monitoring means to improve the variable load boiler, coal adaptability
