摘　　要：根据某省生态环境厅对企业SO2排放值小时平均值小于35 mg/m3,NOX排放值小时平均值小于50 mg/m3的要求,通过对某半干法脱硫机组控制策略的研究,解决了机组在全负荷段下脱硫控制系统的自动运行,减少了脱硫单耗,提高了机组燃烧效率,同时减轻了监盘人员的操作力度,实现了经济运行,达到了预期目标。According to the requirement of a provincial department of ecological environment for the hourly average value of SO2 emission value of enterprises to be less than 35 mg/m3 and the hourly average value of NOX emission value to be less than 50 mg/m3,through the research on the control strategy of a semi-dry desulfurization unit,the solution was The automatic operation of the desulfurization control system of the unit under the full load section reduces the unit consumption of desulfurization,improves the combustion effi ciency of the unit,and at the same time reduces the operation intensity of the monitoring personnel,realizes the economic operation,and achieves the expected goal.

关 键 词：SO2排放值 半干法 脱硫单耗 燃烧效率 经济运行
