超临界循环流化床锅炉技术

Analysis on the Development of Supercritical CFB Boiler Technology

循环流化床(CFB)锅炉大型化的发展方向是开发超临界CFB锅炉。目前CFB锅炉的参数最高为亚临界参数,国内外十余台已投运的300 MW级CFB锅炉运行表明,CFB锅炉在清洁燃烧方面已经充分显示了其优越性,但仍需要向先进的超临界参数发展。对超临界CFB锅炉的特点进行了分析,提出了应研究的关键技术,介绍了国际上首台超临界CFB锅炉的最新进展。

The scaling-up tendency of CFB boiler is to develop supercritical CFB boiler. The maximum parameter of CFB boiler is supercritical parameters at the present time. Operation of ten and more 300 MW grade CFB boilers in domestic and foreign countries have shown that CFB boilers has displayed sufficient superiority in clean combustion side, but also needed to develop to advanced supereritical parameters. The technical features of supercritical CFB boiler were analyzed, key-technologies needing to research in supereritical CFB boiler development being put forward, the new progress of first supercritical CFB boiler in abroad was introduced in this paper.
