【摘要】 垃圾衍生燃料(Refuse Derired Fuels-RDF)具有热值高、易燃烧的优点。一个潜在应用是与煤进行混烧,替代一部分锅炉燃烧用煤。但由于RDF挥发份相当高造成燃烧时的污染物排放不易控制。本文在非均匀布风流化床中进行了RDF与煤的混烧试验,测量了H2O、CO、CO2、NO、N2O、HCl、SO2等物质的排放特性。结果表明与单纯燃烧RDF相比,混烧时的CO生成量大大下降;随着RDF混烧份额的增加,NO生成量近似呈线性增加;混烧时,SO2生成浓度较低,而HCl的生成量比单纯烧煤时明显增加。更多还原

【Abstract】 Refuse Derived Fuels (RDF) has very high volatile content and heating value, is a kind of good fuel, which can be co-fired with coal in boilers. But, the higher volatile content will make the emitted pollution uncontrolled. This paper introduces the RDF and coal co-firing in an uneven air distribution fluidized bed furnace, and measured results of H2O,CO,CO2,NO,N2O,HCl, SO2 emissions. The results show that the CO emission in flue gas is significantly lower than pure RDF if coal is co-fired, but the HC1 is much more since RDF has more Chloride in it If the RDF percentage is increased, the NO is also increased proportionally, and the SO2 content is reduced.更多还原
