Abstract
A turbine, including a rotor on a shaft, and having in combination stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on the rotor; internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor; seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, turbine operations producing shaft power.
Claims17
A turbine, including a rotor on a shaft, and having in combination:
- a) stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on said rotor,
- b) internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor,
- c) seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages,
- d) turbine operation producing shaft power.
The combination of 1 wherein certain of said seal means are provided at the same diametric location on opposite sides of the rotor to produce a force balance on the rotor.
The combination of 1 in which additional rows of stationary nozzles, rotor passages and seal means are provided on the same rotor and oriented in radially outward directions to enable additional power producing steam expansions.
