动力煤选煤厂节能途径分析

Energy-saving methods of steam coal preparation plant

为提高动力煤选煤厂的节能减排水平,减少从能源生产到消费各个环节中的消耗、损失和浪费,促进动力煤选煤厂的清洁高效发展。基于对山西省某10 Mt/a的大型动力煤选煤厂从总平面布置的合理性、选煤生产工艺和工艺流程的选取、主要耗能设备的选择等方面的研究,提出了动力煤选煤厂主要节能途径。结果表明:动力煤选煤厂主要节能途径包括合理进行总平面布置、采用先进生产工艺、选用适应煤质和市场变化的工艺流程、选取高效低耗设备并加强对企业的用能管理等方面。

In order to improve energy- saving efficiency of steam coal preparation plant,reduce energy loss in each link of production and consumption,promote the clean and efficient development of steam coal preparation,a 10 Mt / a coal preparation plant was chosen as research object. The main energy- saving methods were provided from the aspects of plant layout,production process and the choice of technological process,key energy- consumption equipment. The results showed that the major energy- saving ways of steam coal preparation included reasonable general layout,advanced production technologies,production process that adopted to coal quality and market changes,efficient equipment,strengthen energy management.
