摘要:
A turbine (1) has a control and regulating device with a pump (31) whose pressure varies as the square of the volume delivered by the pump or as the square of the rotational speed (n ) of the turbine (1). The hydraulic sequential piston arrangement comprising a preliminary control piston (41) and a control piston (5) for regulating the rotation speed of the turbine is supplied by a single pump (31). A compact, space-saving construction is thereby achieved. The turbine is suitable for use as a motor or drive in applications other than the generation of electricity, for example for cable winches.

A system (12) includes a solvent gas processing system having a high pressure reaction vessel (18) configured to remove an acid gas from an untreated feed gas using a solvent in a lean solvent fluid stream. The system includes a high pressure reaction vessel (18) configured to output a treated clean gas and a first flow of a high pressure fluid stream via a first flow path (28). The system includes a turbine (42) having a main nozzle (54), an auxiliary nozzle (58), and an outlet (59). The main nozzle (54) is configured to receive a second flow of the high pressure fluid stream from the first flow path (28) via a main flow path (52). The system includes an auxiliary nozzle valve (46) disposed along an auxiliary flow path (56). The auxiliary nozzle valve (46) is configured to control a third flow of the high pressure fluid stream into the auxiliary nozzle (58) of the turbine (42).

A wave power capture system, comprises a fluid transfer conduit for connection to a wave energy conversion device such that, in operation, the wave energy conversion device pressurises fluid in the fluid transfer conduit in response to wave motion; a turbine apparatus arranged to receive fluid from the fluid transfer conduit; at least one sensor for sensing pressure and/or flow rate of the fluid; a variable opening valve for controlling the rate of flow of fluid from the fluid transfer conduit to the turbine apparatus; a controller for controlling operation of the variable opening valve in dependence upon the pressure and/or flow rate of the fluid sensed by the sensor and/or the speed of rotation of the turbine apparatus; and an electrical power generation system for obtaining electrical power from operation of the turbine apparatus.
摘要:
A Pelton turbine is disclosed that includes at least one needle valve injector assembly and at least one high efficiency injector assembly. The high efficiency injector assembly provides a generally unimpeded flow path for water from a distributor to a runner of the turbine. The high efficiency injector assemblies and needle valve injector assemblies are operated in cooperation to provide the overall desired flow rate through the turbine and to increase the efficiency of the turbine. A high efficiency injector assembly may be retrofitted for a needle valve injector assembly to improve the efficiency of existing turbine systems.

An impulse turbine system (10) includes a rotatably mounted turbine wheel (12) and a speed sensing system (40) to sense the speed of the turbine wheel (12). A flow diversion nozzle (14) normally provides a jet of driving fluid to power the turbine wheel (12). This nozzle (14) includes an internal flow diverter (30, 38, 58, 74, 76, 88, 90, 94, 104, 110, 118) which operates under the control of the speed sensing system (40) when the turbine wheel (12) reaches an overspeed condition to angularly divert the jet of driving fluid issuing from the nozzle opening (26).
