中国清洁煤炭能源战略思考

Consideration of clean coal energy strategy in China

根据中国能源资源的国情,阐述煤炭能源的高效清洁利用仍然是我国能源研究领域的重中之重。以矿物加工工程和化学工程学科为基础,论述我国清洁煤炭能源的特点以及煤炭的加工和转化技术,指出高效煤炭加工利用的新技术、新工艺必须纳入新能源规划的考虑范围之内。传统的煤加工与煤转化理论和技术面临着严峻的挑战。煤基多联产是符合我国国情的煤炭清洁高效利用新技术系统,是最经济有效的方法。建设大型坑口电站是当前资源配置最优化、最经济、最洁净能源的战略。二段干法选煤的灰分<8%,硫分<5%,该技术既可用于新建电厂也适用于老厂改造。

The clean and efficient utilization of coal energy remains the most important in energy research field,as is determined by the energy resources conditions of China.The new energy plan is dominated by novel process and technology designed for clean and efficient utilization of coal.As the traditional theory and technology of coal processing and coal conversion are confronted with serious challenges,coal-based poly-production represents the new technical system of the efficient and clean use of coal,which applies to China＇s conditions.It follows that the construction of the pithead power plant forms the optimized,most cost-effective and cleanest energy strategy.The two-stage dry separation capable of ash of less than 8% and sulfur of less than 5% is suited to newly built power plants and to upgrading the old ones.
