摘　　要：为指导低压小容量CFB锅炉合理选择环保改造技术路线,选取某热电厂3台75 t/h CFB锅炉为研究对象,对采用脱硝改造、脱硫改造、除尘改造后的锅炉进行了性能测试。结果表明:采用高效低NO_x燃烧技术、石灰石-石膏湿法脱硫系统、袋式除尘器可达到改造目标,且能保证设备稳定运行。To guide the selection of environmental protection retrofit schemes for low-pressure small-volume circulating fluidized bed(CFB) boilers, performance tests were conducted on 3×75 t/h CFB boilers in a thermal power plant after the implementation of retrofits respectively for the denitration, desulfurization and dust collection unit. Results show that, by adopting the high efficiency low NO_x combustion technology, the limestone-gypsum wet flue gas desulfurization(WFGD) system and the bag filter, the goal of retrofit has been reached, under the premise that corresponding facilities work stably.
