摘要
褐煤直接燃烧发电是褐煤利用的重要途径。介绍褐煤发电及褐煤循环流化床(CFB)锅炉技术的发展现状,从燃烧稳定性、锅炉效率及污染物排放等方面,对煤粉锅炉与CFB锅炉褐煤发电技术进行了技术经济对比分析,结果显示:燃用褐煤的CFB锅炉在燃烧稳定性、锅炉效率和污染物减排方面比煤粉锅炉更具优势,在"十四五"期间开发燃用高水分褐煤的600~1000MW超超临界CFB锅炉机组是可行的,并且具有一定的战略优势。
Direct combustion of lignite for generating electricity is an important way to utilize lignite.Development status of lignite power generation and lignite Circulating Fluided Bed(CFB)boiler technology is introduced in this paper.From the aspects of combustion stability,boiler efficiency and pollutant discharge,the technical and economic comparative analysis of lignite power generation technology of pulverized coal boiler and CFB boiler is carried out.As a result,CFB boilers burning lignite have more advantages than pulverized coal boilers in combustion stability,boiler efficiency and pollutant emission reduction.The development of 600-1000MW ultra-supercritical CFB boiler units burning high moisture lignite during 14th Five-Year Plan period is feasible and has certain strategic advantages.
