Study on the coal ash fusibility during blending coal combusition
配煤燃烧过程中煤灰熔融性研究

The experiments to simulate the slagging processes in the power plant boilers were carried out in a drop tube furnace with Shenhua coal,Zhungar coal and the blends of these two coals which are of different ash fusion temperatures.SEM and XRD techniques were used to analyze the surface morphology as well as the crystalline compositions of the residue.The result shows that a great mass of kaolinite and boehmite in Zhungar coal are turned ioto mullite.There is no boehmite and less kaolinite found in Shenhua co...
