Abstract:Taking the steam turbine C250/N300-16.7/537 of Mudanjiang Second Power Plant as example, the technical features of the heat pump system of the small turbine(feed pump driving turbine)were introduced. The technical specifications of the steam turbine, the steam pump and the heat pump were expounded. The economical effect of the heat pump was analyzed. The problems existing in reformed heat pump system were analyzed, and the solutions were given. The practice verifies that the absorption heat pump technology is a mature, economical, safe and reliable heat recovery technology. Favorable social and economic effects were obtained due to the reformation.
