ABSTRACT:
A fluid feeding apparatus can gradually elevate the head of a fluid of steam/liquid mixture by recirculating the fluid through a centrifugal pump of moderate output and an injector. The fluid ejecting out of the nozzle of the injector will entrain a steam/liquid mixture of high latent heat from a fluid intake port so that the heat energy of the condensate from the other sources can be recovered and reused. By virtue of providing a gas intake port for the injector, the fluid can be supplemented with gas wherever needed. Due to the substantial volume of the gas phase in the reservoir, the internal pressure of the reservoir will not increase drastically because of the dampering effect of the gas phase. Thus only a centrifugal pump of moderate output is needed for implementing the recirculation of the elevation of the pressure in the reservoir.
