  • Pressure regulating apparatus for a closed water circuit
    Patent number: 4301650
    Abstract: A method and apparatus for regulating the pressure of water in a closed hot water circuit is disclosed. The apparatus includes a closed hot water circuit and a steam circuit, which water circuit and steam circuit are both heated by relatively hot waste gases exhausted from a gas turbine power plant. Two water lines link the water circuit to the steam circuit. A valve in each of these lines regulates a flow of water through each of the lines. A pressure sensor senses the pressure of the water in the water circuit. The pressure sensor communicates said pressure to a valve regulator, which valve regulator regulates the opening and closing of the valves in the water lines.
