焦作电厂６７０ｔ／ｈ锅炉燃用煤质为无烟煤、低挥发分贫煤，运行中主要存在低负荷稳烯能力差、结渣等问题，为此采用水平浓缩煤粉燃烧器对原燃烧器进行改造。文中给出新型燃烧器及百叶窗煤粉浓缩器的设计及运行参数。改造后燃烧器实现了５０％负荷长期无油稳定运行，锅炉燃烧效率提高，没有发生结渣影响运行的现象。
The burning coal of 670t / h boiler in Jiaozuo Power Plant is anthracite with low volatile and lean coal. There are mainly problems such as poor steady load and poor slagging performance during slagging operation. For this purpose, a horizontal concentrated pulverized coal burner is used to reform the original burner . In this paper, the design and operating parameters of new burner and shutter coal concentrator are given. After the transformation of the burner to achieve 50% load long-term oil-free stable operation, the boiler combustion efficiency, there is no slagging affect the operation of the phenomenon.
