  • Method and apparatus for providing process steam of desired temperature and pressure
    Patent number: 4352270
    Abstract: A method and apparatus for extracting steam from a steam turbine and adjusting the temperature and pressure for a process. Steam is extracted from the first section of the turbine and is throttled to a desired pressure for use in the process. After the extracted steam is throttled it is transmitted to a suction port of a jet pump. If the pressure of the extracted steam entering the jet pump suction port is less than the desired process pressure, high pressure steam is routed to an inlet port of the jet pump. Steam leaving the jet pump may be desuperheated. Regulation of the steam flow between the first and second section turbines increased extraction pressure. At some point total efficiency of turbine operation and process operation can be improved by extracting steam from a second, higher pressure extraction location.
