摘要： The invention is concerned with an improvement in a steam turbine having a boiler having a first superheater, a first conduit having an inlet end and an outlet end, said outlet end being connected to said first superheater, a pressurized liquid working fluid source connected to said inlet end of said first conduit, said first superheater being adapted to convert said liquid working fluid to superheated vapor, a second conduit having an input end and an output end, said input end being connected to receive said vapor from said superheater, and a turbine connected to receive said vapor from said output end of said second conduit. The improvement comprises a structure for restricting flow through the second conduit. A third conduit is adapted to conduct a first portion of the superheated vapor from the second conduit from downstream of the restricting structure to a second superheater wherein the first portion of the superheated vapor is further superheated. The fourth conduit is adapted to conduct the further superheated vapor from the second superheater to the turbine. The result is improved utilization of the heat generated by the boiler whereby significant increases in output energy result.

摘要： There is provided a combined cycle power plant in which a high-pressure steam turbine and an intermediate-pressure steam turbine can operate in a state where amounts of thermal effect thereof are close to a limit value, and capable of reducing start-up time. A combined cycle power plant includes: an exhaust heat recovery boiler that includes a high-pressure superheater which superheats steam for a high-pressure steam turbine, and a reheater which reheats steam for an intermediate-pressure steam turbine; bypass pipes through which steam bypasses the high-pressure superheater and the reheater; bypass valves that regulate flow rates of steam which flows through the bypass pipes; and a bypass controller that controls the bypass valves such that a difference between thermal effect-amount margins of the turbines is decreased.

摘要： A method and apparatus for converting high pressure, high temperature elastic fuild (such as steam) to elastic fluid having a desired relatively low pressure and low temperature. Relatively high pressure, high temperature steam supplied from any point (preferably from a steam drum or equivalent location) in a steam cycle is initially throttled from a high temperature and pressure to a relatively intermediate temperature and pressure. Such intermediate temperature and pressure steam is routed through the tube side of a heat exchanger and subsequently throttled to a relatively low temperature and pressure. The resulting low temperature and pressure steam is then separated into its liquid and vapor phase components wherein the vapor phase is transmitted through the shell side of the heat exchanger and absorbs heat from the intermediate pressure, and temperature steam. The relatively low pressure, low temperature steam exiting the heat exchanger has the desired thermodynamic state. The temperature of the steam exiting the heat exchanger may be regulated by adjusting the high to intermediate pressure throttling device and the pressure of the low pressure steam exiting the heat exchanger may be regulated by adjusting the intermediate to low pressure throttling device. Such temperature and pressure regulation permits maintenance of steam temperature and pressure leaving the heat exchanger for varying temperatures and pressures of the relatively high pressure, high temperature steam supply. Such temperature and pressure maintenance enables elastic fluid utilizing devices to operate efficiently and reliably for fluctuating pressures and temperatures of the supply source.
