Status and development direction of lignite dehydration upgrading technologies
SHANG Qingyu
Abstract：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.
