Test study on operation of primary air fans in 1 000MW unit of Datang Chaozhou Power Generation Co.
Ltd.was performed.The results show the primary air fans have large margin and low operation efficiency.Thus
the original AST-2030/1400B primary air fan with blade profile of PP114 was transformed into AST-2030/1400B with blade profile of PP115.Two years running shows the air fan works stably.The annual saved electricity by the improved primary air fans can reach up to 4 892 300(kW·h)
indicating the investment can be recovered within one year.
