Steam power plant

Abstract

A steam power plant is shown which comprises a pressurized deaerating feed water tank, a high-pressure steam boiler, a high-pressure steam turbine, a low-pressure steam turbine, and a water-cooled, steam condenser, connected in series in a closed circuit. The condenser is maintained under a substantial pressure during operation and connected to supply feed water to the feed water tank. A steam-operated deaerator is connected to the feed water tank to remove air from the water therein. A steam jet is connected between and operable to move steam from the low-pressure turbine to the condenser. A steam jet is connected between and operable to move water from the condenser to the deaerator. A second steam jet is connected to the deaerator to provide steam to scrub the oxygen from the incoming water and permit introduction of a secondary steam source to provide heat as needed. A high-pressure, water injector is connected between and operable to move water from the feed water tank to the boiler. The key to this system is to use injection water of higher pressure than boiler drum pressure. An independent water cycle is required.
