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.
