摘　　要：利用模糊数学的原理,将燃料特性方面的综合指数R、碱酸比(B/A)、硅比G、硅铝比(SiO2/Al2O3)、软化温度t2和锅炉运行方面的无因次炉膛最高温度φt、过量空气系数α、截面热负荷qF等8个因素结合起来,构成评判因素集,建立锅炉结渣综合评判模型,并结合汕头万丰电厂的运行实际进行验证,结果表明该模型具有较高的可靠性。Based on the fuzzy sets principles, it attempts to select the fuel characteristic of the colligation index ‘R＇, the ratio of alkali oxide to acid oxide, silicon ratio, the ratio of silicon to aluminum and the soften temperature, together with the boiler running parameters of the tiptop temperature, excessive air coefficient and the sectional heat flux to establish a new slagging propensity decision model. Also it is combined with the running fact of Wanfeng Power Plant, the result shows that the model is more credible.
