为实现褐煤合理、高效利用，减轻褐煤利用中的环境污染，阐述了国内外褐煤干燥脱水提质技术现状，论述了国内褐煤干燥脱水提质技术工业化示范项目的进展情况，说明褐煤经干燥脱水提质处理后，可脱除褐煤中大部分水分，发热量显著提高，提质后的褐煤具有较高的附加值，便于运输、贮存及综合利用。针对褐煤干燥脱水提质过程中存在的烟尘排放量大、能耗高、余热难以回收利用、干燥褐煤成型率低、型煤易爆裂产生碎块等问题，从加强褐煤性质和干燥脱水基础理论研究、加强干燥工艺及其配套干燥设备的研发、加强褐煤干燥后产品利用技术研究3方面提出了褐煤干燥脱水提质技术的发展方向。
為實現褐煤閤理、高效利用，減輕褐煤利用中的環境汙染，闡述瞭國內外褐煤榦燥脫水提質技術現狀，論述瞭國內褐煤榦燥脫水提質技術工業化示範項目的進展情況，說明褐煤經榦燥脫水提質處理後，可脫除褐煤中大部分水分，髮熱量顯著提高，提質後的褐煤具有較高的附加值，便于運輸、貯存及綜閤利用。針對褐煤榦燥脫水提質過程中存在的煙塵排放量大、能耗高、餘熱難以迴收利用、榦燥褐煤成型率低、型煤易爆裂產生碎塊等問題，從加彊褐煤性質和榦燥脫水基礎理論研究、加彊榦燥工藝及其配套榦燥設備的研髮、加彊褐煤榦燥後產品利用技術研究3方麵提齣瞭褐煤榦燥脫水提質技術的髮展方嚮。

In order to use lignite reasonably and efficiently and reduce the environmental pollution,the paper introduced the status of lignite dehydration upgrading technologies at home and abroad,discussed the development of corresponding industrialization demonstration pro-jects.The results showed that,the treatment dehydrated most of the lignite moisture,improved the calorific value,increased the added val-ue,made the transportation,storage and comprehensive utilization more convenient.There were still lots of problems during treatment,such <br> as large flue dust emission,high energy consumption,difficult waste heat recovery,low briquetting rate.After briquetting,the briquette blast into pieces easily.In order to resolve these problems,the paper provided the improvement measures from strengthening basic theoretical re-search of lignite properties and dehydration,drying process and equipment development,products utilization affer lignite drying.
