摘要/Abstract

摘要： 以某电厂150 MW循环流化床锅炉为研究对象,就掺烧不同比例煤泥对锅炉燃烧特性影响进行了试验研究。试验通过不掺烧煤泥、掺烧煤泥主泵转速25%和掺烧煤泥主泵转速40% 3个工况进行了对比试验。结果表明,随着循环流化床锅炉掺烧煤泥比例的增加,锅炉平均床温明显降低,更接近于最佳脱硫床温;炉膛温度场分布更趋均匀,更有利于炉内燃烧和受热面吸热;炉内屏式过热器壁温经常超温现象得到显著改善;锅炉主汽温度偏低得到明显提高。

关键词: CFB锅炉, 煤泥掺混, 燃烧特性

Abstract: To study the performance of the combustion system fueled with different proportions of coal slurry mixture, three operating conditions, without peat blending, with peat blending at 25% main pump speed and with peat blending at 40% main pump speed, are tested on a 520-t/h circulating fluidized bed(CFB) boiler in one Power Plant. The results show that with the increase of peat blending ratio, the average bed temperature is significantly reduced and much closer to the optimum desulfurization bed temperature; the distribution of the furnace temperature field is more uniform so that will benefit the furnace combustion and heat absorption; the overheating of the platen superheater wall and the low boiler main stream temperature are substantially improved.

Key words: circulating fluidized-bed boiler, coal slime blending, combustion characteristic
