生物质中较高的碱金属及氯元素含量,使其在与煤混燃过程中引起了过热器管壁的严重腐蚀。综合分析了生物质混煤燃烧过程中的腐蚀作用类型,考查了腐蚀的各种影响因素,并对炉内温度、燃料成分、炉内气氛、金属材质等因素进行了探讨。 The higher content of alkali metals and chlorine in biomass causes it to cause severe corrosion of the superheater tube wall during co-firing with coal. The types of corrosion during the combustion of biomass mixed coal were comprehensively analyzed. Various influencing factors of corrosion were examined. Factors such as furnace temperature, fuel composition, furnace atmosphere and metal material were also discussed.
