我国选煤厂煤泥干燥技术应用现状与发展趋势

Coal slime thermal drying technologies applied in China's coal preparation plants-current status and developing trend

煤泥是选煤厂的洗选副产品,由于其自身水分高、粘性大、热值低的特点,无法实现大规模与资源化利用。就目前的技术条件来看,干燥是提高煤泥质量的有效途径,也是实现有效利用的基础手段。针对目前我国选煤厂应用的煤泥干燥技术进行了分析,并就其未来发展趋势进行了预测。

As a by-Product of coal cleaning plant, coal slime is characterized by its high moisture and viscosity and viscosity and low calorific value, a nature making it impossible to be utilized as an energy on an extensive basis. Viewed from the existing technological conditions, thermal drying is the most effective approach and basic means for the upgrading of coal slime. The paper presents an analysis of the thermal drying technologies currently applied in Chinag coal preparation plants and a forecast of their developing trend.
