生物质与煤共燃结渣特性的研究

Study on slagging characteristics of co-combustion of biomass and coal

生物质与煤各自特性的差异以及生物质与煤共燃的过程中发生的复杂反应,现有的煤灰的结渣指标无法准确地预测生物质与煤共燃的结渣倾向.根据模糊数学中的模糊判断理论,利用熔融温度t2、碱酸比B/A、硅铝比S/A、硅比G等多项煤灰结渣指标建立模糊综合评判模型,对生物质与煤共燃的结渣情况做出预测.

Since the difference between combustion characteristics of biomass and coal and the complex reactions in the process of combustion, the existing slagging discrimination index of coal ash can not provide an accurate prediction about the slagging tendency of co-combustion of biomass and coal. Aiming to improve the existing slagging discrimination index, a fuzzy comprehensive evaluation model was built by utilizing several decisive slagging discrimination indexes based on the fuzzy theory to predict the slagging trendency of co-combustion of biomass and coal.
