摘要:

摘要:某电厂300MW火电机组超低排放改造后,引风机与增压风机联合运行方式不能满足使用要求,因此进行“引增合一”改造。文章采用热态试验及性能曲线对运行现状及风烟系统阻力进行分析,确定“引增合一”改造方案。取消增压风机后,不仅新引风机综合效率将得到较大提高,而且有利于机组安全、稳定运行。

Abstract:

Abstract:After ultralow emission improvement, the joint operation of induced fan and booster fan of a power plant’s 300MW thermal power unit did not satisfy the use requirement. Hence, the unification of induced fan and booster fan was carried out. Authors adopted hot state test and performance curve to analyze working status and air and flue gas system resistance, and determined the unification plan. After removed booster fan, the comprehensive efficiency of new induced fan is significantly increases. Unit operation safety was ensured. 
