开发超临界循环流化床(CFB)锅炉是国际CFB界的目标,它兼备了清洁利用劣质燃料和高效发电两个优势,对于煤炭的清洁开发利用具有至关重要的地位.中国的科技人员在国家863计划和国家科技支撑计划的支持下,开展系统的研究开发,全面突破了300MW亚临界自然循环跨越到600MW超临界强制循环带来的巨大的理论和工程挑战,回答了工程上提出的科学和技术问题,在神华白马电厂成功建设了世界上第一台600MW超临界CFB锅炉及相应的辅助系统.进而将这些研究成果成功拓展用于350MW超临界CFB锅炉上,已经批量投产.这些研究积累为开发提供了基础.目前正在开展660MW超超临界CFB锅炉的技术关键如热偏差、超低排放、低能耗等研究,并已经取得了阶段性进展.
Research and Application of Supercritical and Ultra-supercritical Circulating Fluidized Bed Boiler Technology
To develop supercritical circulating fluidized bed (CFB) boiler is objective of international CFB circles because supercritical CFB boiler combines the advantages of CFB combustion of low cost emission control and supercritical steam cycle of high efficiency of power generation.It is also most important for low rank coal utility.With the support of High Technology R&D Program (863) and Key Project of the National Research Program of China,Chinese researchers investigated systematically the issuers of supercritical CFB boiler development.And the huge theoretical and engineering challenges from 300MW subcritical natural circulation leaping to 600 MW supercritical once through are comprehensively broken.And the first 600MW supercritical CFB boiler and its auxiliaries were successfully developed and demonstrated in Baima Power Plant,Shenhua.Then the investigation results have been successfully expanded into 350MW supercritical CFB boilers design and have been commercialized widely.These studies provide the basis for the development of ultra-supercritical CFB boiler.Now,the key technologies such as heat deviation,ultra-low emission,and low electric power consumption are being investigated.And some preliminary achievements has been made.
