较全面地总结和评述了我国低挥发分煤燃烧技术的发展 ,指出“W”型火焰锅炉的大致适用范围是Vdaf=10 %~ 15 %的较难着火燃尽的贫煤 ,其中属中等着火性煤仍可采用常规燃烧方式 ;应避免特性相差很大或不同煤种的混烧 ,若不得不掺烧时 ,应特别注意燃烧系统及其相关设备的设计和运行调试。认为当前应强化低挥发分煤的不同燃烧技术的研究 ,着重“W”型火焰锅炉的完善化、不同煤种混烧和液态排渣炉低NOx 燃烧技术的研究 ,以适应低挥发分煤燃烧的不同需求。
The development of low-volatile coal combustion technology in China is summarized and reviewed. It is pointed out that the general applicable range of “W” -type flame boiler is moderately ignited lean coal with Vdaf = 10% ~ 15% Coal can still be used conventional combustion; should be avoided with very different characteristics or different kinds of coal mixed burning, if you have to mix, you should pay special attention to the combustion system and related equipment design and commissioning. It is considered that the research on different combustion technologies that should strengthen low-volatile coal should be focused on the improvement of the “W” flame boiler, the research on the low-NOx combustion technologies of different kinds of coal and the liquid slag dischargers to adapt to the low-volatile coal combustion Different needs.
