摘　　要：本文针对生物质水冷振动炉排炉锅炉在运行中出现的高温腐蚀问题,以某生物质电厂锅炉为例,在分析高温腐蚀机理的基础上,对增加熔敷、改进二次风管设计、优化受热面布置的缓解高温腐蚀方案进行了阐述分析,可为工程中类似问题提供一定的借鉴经验。This paper addresses the problem of high-temperature corrosion of biomass water-cooled vibrating grate boiler in operation. Taking a biomass power plant boiler as an example, based on the mechanism analysis of high-temperature corrosion, this paper elaborates and analyzes the mitigation scheme of high-temperature corrosion by adding deposition, improving the design of secondary air ducts, and optimizing the heating surface setting. It can provide some experience for similar issues in engineering.
