燃煤工业锅炉氮氧化物污染防治技术路线

摘要

针对工业锅炉氮氧化物的产生特点和控制难点，提出工业锅炉氮氧化物的治理要从加强锅炉行业的设计和制造水平入手，开发适合国情的氮氧化物削减技术，发展城市集中供热和园区集中供气替代小型燃煤锅炉，新建锅炉房采用低氮燃烧技术，重点地区采用低氮燃烧技术和以 SNCR 为主的尾端治理相结合%　　Based on the NOx emission characteristics and the difficulty of control of coal-fired industrial boilers, proposed some measures to reduce NOx : strengthen the industry boiler design and manufacturing level, develop nitrogen oxides cutting technology, build heating plants in urban and industrial park replace small coal-fired boiler, the newly built boiler with low nitrogen combustion and(or) the SNCR.
