| Abstract: | This paper presents the computation of the design of the recovery system concerning steam condensate heat. The equation of the changing from steam phase to liquid state in the condensate is established. The coupling function of the ejector between consendate unit and recovery pump of the hot consendate is studied. The paper sets up the fluid continuity equation, the heat equilibrium equation and the efficiency formula of the ejector and points out the technical key to prevent the hot condensate from changing into steam phase. The energy equations when the fluid passes through the recurrent passage and from the pump to the exit are obtained. Finally, a diagram of an application is given and the technical questions of the computation of the design of the recovery device are discussed. |
