摘要:

为了更好地解决燃用无烟煤锅炉在选型时遇到的煤的着火、稳定燃烧和燃尽等技术问题,结合实际工程应用,对600 MW超临界W型火焰锅炉和超临界循环流化床(circulating fluidized bed,CFB)锅炉的炉型及运行性能进行了分析与比较。研究结果表明, W型火焰锅炉燃用无烟煤时燃烧性能好,但炉膛出口NOx浓度较高,同时受热面高温腐蚀问题也不容忽视;CFB锅炉燃用无烟煤时燃烧稳定、炉膛出口NOx浓度小,但燃尽性能有待提高。建议600 MW无烟煤超临界锅炉应优先选择超临界CFB锅炉,并通过合理技术途径提高其燃尽性能。

Abstract:

In order to better solve the technical problems during the selection of anthracite-fired boiler such as ignition, stable combustion and burnout, the configuration and operation performance were analyzed and compared between 600 MW supercritical W shaped flame boiler and supercritical circulating fluidized bed (CFB) boiler combined with practical engineering application. The research results show that, W shaped flame boiler has good combustion performance when burning anthracite, but has higher concentration of NOx at furnace outlet, and high temperature corrosion problems of heating surface cannot be ignored. However, the NOx concentration at furnace outlet is relatively low and the combustion is stable for anthracite-fired CFB boiler, but the burning performance needs to be improved. It is suggested that supercritical CFB boiler should be preferred option for 600 MW anthracite-fired supercritical boilers, and it is necessary to improve the burning performance through reasonable technical way.

Key words: supercritical boiler, boiler type-selection, W shaped flame boiler, supercritical circulating fluidized bed (CFB) boiler, stable combustion, anthracite coal
