摘要
对某生物质直燃发电炉排炉的炉内腐蚀情况进行分析,利用XRD对炉排渣块、过热器沉积焦成分进行了定量分析,利用高温热天平对其进行深入的热反应动力学研究。试验结果表明:渣块的形成是因为物料堆积造成生物质燃料长时间缺氧燃烧热解,成分主要是未燃尽碳。过热器沉积焦的形成是因为生物质燃烧过程中碱金属及碱土金属的沉降凝结,遇高温可再次析出。
Articles of a biomass-fired power generation grate furnace corrosion was analyzed. Furnace slag blocks and superheater deposited coke Components were quantitatively analyzed by XRD. Furnace slag blocks and superheater deposited coke components was carried out in-depth studies of thermal analysis using high-temperature heat balance. The results showed the formation of clinker was caused by material accumulation, due to local hypoxia caused anoxic pyrolysis of biomass fuels formation, and its composition was mainly unburned carbon. Superheater deposition coke was due to the combustion of biomass formed during the alkali metals and alkaline earth metals coagulation sedimentation caused be re-precipitation when the temperature increase.
