Abstract:

Abstract:The advantages and disadvantages of three different water feed modes of the 300MW unit in a power plant in startup stage were analyzed. The operating process of water feed mode of turbinedriven feed pump assisted by electric feed pump was introduced, and the matters needing attention in operation were summarized. After the optimization, the reliability and economic efficiency of unit startup were improved.
