Research on the Influence of Coal Quality on Sludge Coal Slurry Property

Abstract:

Through the coal quality feature, five kinds of coal samples are determined as soft coal, and they are Pingdingshan coal, Yanzhou coal, Xuzhou coal, Zhungeer coal and Shenhua coal respectively according to the coal rank from high to low. With Alfred grain composition model, the municipal sludge with five kinds of coal samples and 95% moisture content (hereinafter referred to as sludge) is conducted the slurry property experiment, we can find that the sludge coal slurry belongs to the false body fluid featured with shear thinning, which is conducive to the pumping and atomization combustion of the sludge coal slurry. The higher the degree of coal metamorphism, the greater the limit concentration of sludge coal slurry, the better the rheological property, and the stability is better.
