摘　　要：分析了某小型电厂燃煤机组烟气超低排放改造工程实例,通过采取加装旋流板除尘除雾器、改善烟气分布、增加脱硫气液比、低氮燃烧改造等措施,实现烟气中烟尘、二氧化硫、氮氧化物达到超低排放标准要求,具有一定的实践意义。This paper introduces and analyzes the transformation project of ultra-low emission of flue gas from a coal-fired unit in a small power plant. By installing a cyclone plate dust remover, improving the distribution of flue gas, increasing the ratio of desulfurized gas to liquid and reforming low nitrogen combustion, the dust, sulfur dioxide and nitrogen oxides can satisfy the ultra-low emission standard requirements. It has certain practical significance.

关 键 词：燃煤机组 脱硫气液比 烟气分布 超低排放
