摘要 为验证煤粉锅炉技术替代传统燃煤工业锅炉的节能环保优势,促进我国煤炭清洁燃烧领域的变革和发展,以近年来神东煤炭集团公司高效煤粉锅炉系统技术工程化应用为实例,介绍了该技术在神东煤炭集团公司下属6个矿区共18台锅炉(合计516蒸t/h)的工程建设和示范运行,统计了系统运行2个采暖季的节能效益。神东6个矿区锅炉房锅炉平均热效率达90%以上;用户认可的节煤率达52%,因节能带来的收益超过1.5亿元;系统运行2个采暖季共减排烟尘210 t、SO2467 t、NOx643t。结果表明:高效煤粉锅炉系统运行稳定,锅炉热效率高。锅炉系统正平衡效率93.21%、反平衡效率90.42%、平均效率91.82%。节能减排效益显著,是传统燃煤锅炉理想的替代品,适合在我国燃煤工业锅炉领域大规模推广。 In order to verify the advantages of pulverized coal boiler versus traditional industrial coal-fired boiler and promote the develop-ment of coal combustion in a cleaner way,an efficient pulverized coal boiler system developed by Shendong Coal Group was taken as re-search object. The technology was adopted by 6 mining areas of Shendong Coal Group and its application in 18 boilers whose stove load was 516 t/h in total was investigated. The reduction of flue dust,SO2 and NOx were 210,467,643 t during two heating seasons,the energy-saving benefits was calculated. The average thermal efficiency of 18 boilers was above 90%,the rate of coal saving was about 52%,the en-ergy-saving benefits was RMB 1. 5×108. The results showed that,the efficient pulverized coal boiler system had high thermal efficiency and stable performance. The positive,negative and average thermal balance efficiency was 93. 21%,90. 42%,91. 82%,so the efficient pulverized coal boiler system technology fit in the traditional industrial coal-fired boiler.
