PURPOSE:To contrive reduction of the maximum utility pressure of a condensating system by reducing a full lift of a condensate pump, by providing an air extractor and a water feeding system for a gland steam condenser by branching from a condensating system. CONSTITUTION:Condensate discharged from a condensate pump 4 performs water feeding to an air ejector and a gland steam condenser 9 by providing a small diameter branch condensate pipe 15 which is once ramified from a main flow of condensate piping 15 and providing further a small capacity pump 16 after impurities of the condensate have been removed by a filter 5 of the condensate and a desalting device 6 of the condensate. To make a quantity of feeding water constant a flow meter 17, a liquid quantity adjusting device 18 and an adjusting valve 19 are provided additionally. With this piping application, the full lift of a condensate pump is reduced, and it becomes possible that the maximum utility pressure of a delivery line of the condensate pump is made to fall within a range of under 20kg/cm<2>g, water chambers of the air ejector and the gland steam condenser become fed to only a required quantity of water and the diameters of the water chamber and the condensate pipe are reduced. |
