摘　　要：通过高含碳飞灰泥与煤水混合物在小型电加热流化床锅炉中的燃烧试验 ,研究了水分含量、煤的混合比例、床温、停留时间等因素对飞灰泥与煤水混合物结团特性的影响 ,并考察了流化床结团燃烧效果。试验结果表明 ,高含碳飞灰泥与煤水混合后在流化床的结团燃烧可有效地降低飞灰中的含碳量 。Through combustion experiments in an electricheated laboratoryscale fluidized bed combustor by using flyash slurry with high carbon content and coalwater mixture as fuels, the inflence of some factors, such as moisture content, mixed ratio of coal, bed temperature, and retention time etc., upon agglomeration behavior of flyash slurry and coalwater mixture has been studied, and the fluidized bed agglomeration combustion effects being investigated. Results of experiments show that the fluidized bed agglomeration combustion using abovementioned fuels is able to effectively decrease the carbon content in fly ash, providing a practical way for beneficially using unburnt combustibles in fly ash as a resourse.
