摘　　要：为解决某高参数火电厂旁路烟道蒸发技术实施存在的效能不高问题,开展了系统的研究与分析,通过对管路分布和雾化器数据的分析表明:该火电厂干燥塔进出口烟气平均温差仅116℃,干燥塔底渣含水量过高,原因在于烟气进出方式采用上进下出,热交换时间较短,且旋转雾化器振动值过低,雾化不充分,建议采用下进上出的对流传热方式,同时提高旋转雾化器振动值。This study carried out systematic research and analysis on the implementation of the bypass flue evaporation technology of a high-parameter thermal power plant,The reason is that the flue gas inlet and outlet mode adopts the upper inlet and lower out,the heat exchange time is short,and the vibration value of the rotary atomizer is too low,and the atomization is not suffi-cient,so it is recommended to adopt the convective heat transfer mode of the bottom in and out and the vibration value of the rotary atomizer is increased at the same time.
