梳理了微波对褐煤提质干燥技术的现状,论述了褐煤的性质特点,分析了微波对褐煤提质干燥技术原理及特点,重点介绍微波对褐煤提质干燥技术的研究进展,并对微波技术在褐煤洁净转化方向做了展望.褐煤属于低阶煤,具有高水分、低碳、低热值等特点,不能经济地进行开采应用,对褐煤提质是改变其自身价值的关键步骤,其中高水分是对褐煤应用的最大阻碍,因此对褐煤的提质干燥是褐煤应用的基础.采用微波辐照的方法对褐煤进行提质干燥,是一种全新的褐煤干燥方法,较常规干燥具有清洁、环保、高效、节能的优势,符合企业洁净化生产需求.
The status quo of drying technology of lignite by microwave was reviewed. The characteristics of lignite were discussed. The principle and characteristics of lignite drying by microwave were analyzed. The research progress of lignite drying by microwave was emphatically introduced. Lignite is a low-rank coal with high moisture, low carbon and low calorific value, which can not be economically exploited. Lignite upgrading is a key step to change its own value. High water content is Lignite is the biggest obstacle to the application of lignite, so lignite quality is the basis for the application of lignite.Using microwave irradiation method to lignite drying, is a new lignite drying method, compared with conventional drying with a clean, environmentally friendly, Efficient, energy-saving advantages, in line with corporate clean production needs.
