Research on the Suspension Combustion Rate of Coal Water Slurry

摘要

The atomization suspension combustion of coal water slurry is the extensive technology of its combustion and gasification. Research on coal-water-slurry atomization suspension combustion property is very important. Experiment based on traditional single drop combustion couldn't reflect true atomization, suspension firing of coal water slurry atomization suspension firing test device (ASFTD) was adopted and study on the combustion rate of Shenmu coal water slurry suspension combustion was carried out. The model of Shenmu slurry suspension combustion rate was proposed under this experiment condition. The results show that suspension combustion rate gradually increases with the prolongation of coal water slurry combustion time under different temperature, however，different temperature results in distinct suspension combustion rate change. The trend shows that the suspension combustion rate increases with coal water combustion temperature heightening. It is helpful to design and operation of coal water slurry combustor.
