Abstract
Considering that the lump coal supply falls short of demands, great amounts of fine coal and slime are stockpiled, waste energy is extensive, and environmental pollution is serious, this paper summarizes the present situation of industrial coal briquetting technologies and their applications, and evaluates the advantages and disadvantages of several different coal briquette technologies widely used. The authors think that the energetic development of industrial coal briquetting technology is an effective and feasible option to fully utilize fine coal and slime, mitigate the contradiction between supply and demand for lump coal, reduce the production cost of users, as well as decrease and control environmental pollution caused by coal utilization. It is a practical solution for clean coal in China. At present, the research for developing industrial coal briquetting technologies is in the selection and adoption of suitable binders which need dry processing and can produce high strength and waterproof briquettes.
