为燃用低挥发份无烟煤而开发的新型ＣＵＦ锅炉结合了四角切向燃烧和立式燃烧两种方式的各自优势。用冷态模化方法试验研究了ＣＵＦ锅炉的特性。测量了炉内空气动力场及炉膛出口水平烟道速度分布。试验结果表明，ＣＵＦ锅炉在改善无烟煤着火，稳燃和燃尽方面具有明显的优越性，同时在避免炉膛结渣和降低炉膛出口烟气流速偏差方面也表现出良好性能。 The new CUF boiler developed for burning low-volatile anthracite combines the advantages of tangential and vertical combustion at both corners. The characteristics of the CUF boiler were studied by cold modeling method. The horizontal velocity distribution of the furnace aerodynamic field and furnace exit was measured. The test results show that the CUF boiler has obvious advantages in improving anthracite ignition, stable combustion and burn-out, and also shows good performance in avoiding the slagging of the furnace and reducing the deviation of the flue gas velocity at the exit of the furnace.
