A liquid pump of the present disclosure includes a container, a shaft, a bearing, a pump mechanism, a storage space, and a liquid supply passage. The shaft is disposed in the container. The bearing supports the shaft. The pump mechanism pumps a liquid by rotation of the shaft. The storage space is defined in the container at a position outside the pump mechanism. The storage space stores the liquid to be taken into the pump mechanism or the liquid to be discharged to outside of the container after being expelled from the pump mechanism. The liquid supply passage is a flow path including an inlet open to the storage space and supplying the liquid stored in the storage space to the bearing.

A method and system for heat recovery and/or power plant cooling, incorporating an ejector configured to transfer vapor from a generator to a condenser. The ejector includes a converging-diverging nozzle to create a low pressure zone that entrains a fluid. The ejector is within a cooling fluid cycle line in heat exchange combination with an exhaust flue gas. Two fluid flows of the fluid cycle line are mixed via the ejector into a combined fluid, wherein the ejector adjusts a temperature and/or pressure of the combined fluid. Condensing the combined fluid provides a cooling medium.
