摘要
垃圾电站锅炉高参数化后管壁腐蚀加剧,企业面临优选防护方法的迫切问题。介绍了适合于高参数垃圾锅炉的5种基材(20G、12Cr1Mo VG、15Cr Mo、TP310S、TP347H等)及5种当前主流涂层防护技术(堆焊、感应熔焊、复合感应熔焊、超声速火焰喷涂、热固化陶瓷等),共设计了13种典型的防腐蚀方案。选择高性价比与高经济性两种评价模型,将换热性、热膨胀性、结合强度、孔隙率、稀释率、服役寿命、经济性、生产效率等参数作为评价高温防腐蚀方案的主要性能指标。通过层次分析法分别确定两组权重系数,并采用模糊综合评价法进行定量分析,形成高参数条件下高温防护方案的综合评价技术排名。评价结果说明,该技术效果显著且实用可行。
In view of the intensification of pipe wall corrosion after high parameterization of boilers in garbage power plants,enterprises are facing an urgent problem of selecting optimal protection methods.Five kinds of substrates of 20G,12Cr1MoVG,15CrMo,TP310S,TP347H suitable for high-parameter garbage boilers,and five current mainstream coating protection technologies including surfacing,induction fusion welding,composite induction fusion welding,high velocity oxygen fuel(HVOF)spraying,and heat-curing ceramic,were introduced.And a total of 13 typical anti-corrosion schemes were designed.Two evaluation models of high cost performance and high economy were selected,and the parameters of heat exchange,thermal expansion,binding strength,porosity,dilution rate,service life,economy and production efficiency were selected as the main performance indicators for evaluating the high temperature anti-corrosion scheme.The two sets of weight coefficients were determined by the analytic hierarchy process,and the fuzzy comprehensive evaluation method was used for quantitative analysis to form a comprehensive evaluation technology ranking of high temperature protection scheme under high parameter conditions.The results of the evaluation show that the effect of this technique was remarkable and practical.
