摘　　要：越南汪秘电站330 MW机组设计煤质为V_(daf)=4.94%越南无烟煤,选择W型火焰锅炉配中贮式热风送粉系统,锅炉在试运期间额定负荷下炉膛燃烧区域温度较低,须投入油枪才能保证锅炉稳定运行。通过采取增加卫燃带等措施对锅炉本体进行改造,提高了炉膛燃烧区域温度,实现了不投油枪的锅炉稳定运行,但却带来了炉膛较严重的结焦。对锅炉改造前、后存在的问题进行分析,提出今后燃烧类似煤质的锅炉炉型宜选择循环流化床。The 330 MW unit of Thermal Power Plant in Uong Bi Vietnam is designed to burn anthracite of volatile Vdaf=4.94%, and choose the ＂W＂ flame boiler and storage pulverizing system with hot air. At debugging period unit occurred slagging, unstable combustion oil-free, etc. After retrofit of the boiler, the furnace temperature has been raised and stable combustion oil-free come true, but it had taken the serious furnace slagging. It is suggested that the CFB boiler should be chosen for burning this similar coal because of the analysis for existing problems of this boiler.
