摘　　要：针对某厂240 t/h循环流化床锅炉存在的问题进行了深入分析,制定了相应的节能环保一体化改造方案。改造实施后,锅炉各项运行指标大幅改善,锅炉效率提升1.22%,一次风机和引风机电耗下降10%,氮氧化物原始生成浓度稳定降至180 mg/Nm^3以下,较改造前下降40%以上,有效提升了锅炉低负荷脱硝能力。通过节能环保一体化改造,实现了循环流化床锅炉节能环保的协同治理。For one 240 t/h CFB boiler problems in depth analysis,to develop the appropriate integration of energy-saving environmental rehabilitation programs. After the implementation of the transformation,the boiler operation indicators significantly improved boiler efficiency of 1. 22%,a fan and the wind electrical energy consumption decreased by 10% and nitrogen oxides concentrations stable to generate the original 150 mg/Nm^3 or less than the transformation of the former fell more than40%,effectively increasing the low load boiler denitrification capacity.
