摘要
生物油脂在工业锅炉上的燃烧和污染物排放特性的研究对研究生物柴油在工业锅炉上的应用可行性及锅炉的设计具有较高的参考价值。采用工业锅炉台架试验,测验了7种不同比例的生物油脂掺混燃料的燃烧和污染物排放特征。试验结果表明:工业锅炉在不改变系统和燃烧工况下,低比例生物油脂掺混燃料可在工业锅炉直接使用,当生物油脂掺混体积分数低于30%时,工业锅炉燃烧状况较稳定,工业锅炉烟气中烟尘浓度、一氧化碳、NO_(x)有一定幅度的下降,改善了工业锅炉的污染物排放浓度,生物油脂混合体积分数在20%~30%时,可在工业锅炉直接应用,可改善工业锅炉的燃烧状况并降低了污染物排放浓度,新建的高比例生物柴油工业锅炉炉膛设计可根据其火焰特性进行适当的改进.
The test of combustion and emission characteristics of biodiesel in industrial boilers is of great significance to the study of the applicability of biodiesel in industrial boilers and boiler design.The combustion and emission characteristics of seven biodiesel blends with different ratios were tested in an industrial boiler.The test results show that the mixed fuel of low proportion biodiesel and petrochemical diesel can be directly used in industrial boilers without any adjustment.When the mixed proportion of biodiesel is less than 30%,the combustion condition of industrial boilers is relatively stable,and the smoke concentration,carbon monoxide and NO,,in the flue gas of industrial boilers decrease to a certain extent,The pollutant emission characteristics of industrial boilers are improved.When the volume ratio of biodiesel is between 20%and 30%,it can be directly used in industrial boilers,which can improve the combustion condition of industrial boilers and reduce pollutant emissions.The furnace design of newly built industrial boilers with high proportion of biodiesel can be improved according to their flame characteristics.
