褐煤提质技术的现状浅析

我国有较为丰富的褐煤资源,随着我国经济的发展,煤炭能源的需求进一步扩大,对褐煤的加工利用的需求也不断增加,但是褐煤高水分,高灰分,低发热量以及易自燃等性质使得其不宜经过洗选加工后直接利用,同时也不利于煤炭资源的长途运输以及储运,所以褐煤提质技术逐步发展起来,针对国内外对褐煤提质的研究,总结了褐煤提质技术的分类以及进展,并结合我国褐煤发展的现状对提质技术的发展方向进行了探讨。

Analysis of Current Situation of Brown Coal Quality Upgrading Technology

China has abundant lignite resources. As China＇s economic development, further expansion of coal energy is demanded, and the demand for processing and utilization of brown coal are increasing. Howerer the brown coal has high moisture, high ash content and low calorific value and ease of spontaneous combustion and other properties, so it should not be directly used after washing and processing,while it is not conducive to long-distance transport and storage of coal resources, so browm coal quality upgrading technology is gradually developing. For the studies on browm coal quality upgrading, this paper summed up the classification and progress of this technology,combined with the situation of China, discussed the development direction of brown coal quality upgrading.
