锅炉现有多种燃烧方式，都会发生燃烧产物的能量不平衡，影响工质吸热均匀性。切圆旋转燃烧在未消除残余旋转时，引起对流烟道两侧较大烟温偏差，当与工质吸热偏差迭加后增大热偏差，甚至发生再热器起温爆管。通过多年试验研究，查明了起因，找到了改善措施，经多台锅炉实炉改进后验证试验，取得较好成效，现已总结经验推广应用。 There are many existing combustion methods in the boiler, and the energy imbalance of the combustion products will occur, affecting the heat absorption uniformity of the working fluid. When the residual rotation is not eliminated, the round-burning combustion causes large smoke temperature deviation on both sides of the convection flue. When the deviation from the working fluid increases, the thermal deviation increases, and the reheater starts to explode. After many years of experimental research, the cause has been identified, and improvement measures have been found. After several boiler furnaces have been improved and verified, great success has been achieved. The experience has now been popularized and applied.
