  • Steam generating apparatus and methods
    Patent number: 4573323
    Abstract: Steam generating apparatus and methods wherein a liquid is recirculated within a boiler by use of a constant speed dynamic feed water pump acting both to feed the boiler and to effect recirculating therein by a jet pump with its jet nozzle in liquid flow series with the dynamic pump. The jet pump also receives water from a steam drum for recirculation through the boiler. In the event of excess feed water supply to the boiler a step-function level control for the steam drum bypasses liquid to a condenser. A second jet pump acts to utilize excess feed water to supply cool water from the condenser well under pressure to the dynamic pump so that no water is bypassed to the condenser under on-design operating conditions. For waste heat recovery to provide shaft power automatically with simplified controls.
