Analysis and Countermeasures for Fly-ash Feature from Zhungeer Coal with Electrostatic Precipitation
Zhungeer coal for ESP is a extremely difficult one with low sulfur content (0.43％), low inherent moisture (≯2％), high ash (31.7％), over-high aluminum (Al2O3: 51.72％), middle-high silicon (SiO2: 40.63％), low iron (Fe2O3: 1.38％), low sodium (Na2O: 0.02％), and low potassium (K2O: 0.43％) etc. This kind of coal can, after firing in boiler, result in difficult dust conditions with the light specific gravity, fine particles and high resistivity, but it belongs to green coal due to low sulfur content and has a great number of reserves, and for the future, many power stations will still use it. The present paper, through the analysis of physical and chemical for this coal and contrasting the practice experiences used for industries, proposes requirement of design electrotype and other eligible corresponding measures.
