摘要
东方电气集团东方锅炉股份有限公司(简称东方锅炉)在现有旋风分离器出口烟道的基础上,为进一步提升锅炉性能,自主研发了旋风分离器出口汽冷烟道方案.以某350MW超临界循环流化床机组锅炉为设计验证对象,对汽冷烟道的方案、汽冷烟道的应力、汽冷烟道的磨损等问题进行深入分析,并提出针对性的解决措施.自主研制的旋风分离器出口汽冷烟道已在各等级多台CFB锅炉成功应用,为进一步实现CFB锅炉的清洁、高效利用奠定基础.
Abstract
Based on the existing cyclone separator outlet flue,Dongfang Electric Group Dongfang Boiler Co.,Ltd.(hereinafter referred to as'Dongfang Boiler')has independently developed a cyclone separator outlet steam-cooled flue scheme to further enhance the performance of the boiler.Taking a 350 MW supercritical circulating fluidized bed(CFB)boiler unit as the object of design verification,this paper conducts an in-depth analysis of the scheme of the steam-cooled flue,the stress of the steam-cooled flue,and the wear of the steam-cooled flue,and proposes targeted solutions.The independently developed cyclone separator outlet steam-cooled flue has been successfully applied in various grades of multiple CFB boilers,laying the foundation for further achieving clean and efficient utilization of CFB boilers.
