Abstract: In the #5 boiler of Huadian International Zouxian Power Plant, when the inlet adjustable baffles of primary air fans A/B were opened fully, the motor currents of the fans often can not raised to rated value, and the outputs of the primary fans were restricted, and the capacity extension of #5 boiler were restricted too. The problems existed in system design, installation, operation and maintenance of primary air fan of the boiler were analyzed, and some suggestions for improving the output of the primary air fan were put forward.
