    Fuzzy Comprehensive Evaluation of High Parameter Garbage Power Plant Anticorrosion System Based on Analytic Hierarchy Process

    • 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.
