加内置稳焰体的双通道旋流煤粉燃烧器研究及其在410 t/h锅炉上的应用

摘要

The combustion-stabilizing mechanism of the title burner has been analyzed.The results of test,measurement and study of cold-state simulation have been given.Based on the results of study,the cyclone-type burner of boiler No 3 in Huozhou Power Plant,Shanxi province,has been retrofitted.The results of commercial experiments show,this kind of burner has better fire-stabilizing capability.%分析了加内置稳焰体的双通道旋流煤粉燃烧器的稳燃机理，给出了冷态模拟试验测量及研究结果，根据研究结果对山西霍州电厂3号炉的旋流燃烧器进行了改造。工业试验结果表明，该燃烧器具有较好的稳燃性能。
