Based on the analysis of the feed pump configuration for domestic 1000MW units,which are put in operation or ordered,some opinions on the current configuration and its future development trend of the feed pump for air-cooled units with same capacity and parameters were given.Considering the antifreezing requirement of the air-cooling system sufficiently,the possibility to eliminate the starting electrical pump for direct and indirect air-cooled units was discussed.
