20090320493 | METHOD FOR PRIMARY CONTROL OF A COMBINED GAS AND STEAM TURBINE ARRANGEMENT - A method for primary regulation of a combined gas and steam turbine installation in network operation, wherein the combined gas and steam turbine installation includes a gas turbine and a steam turbine arranged along at least one shaft includes operating at least one steam turbine actuating valve on a restricted basis along a working steam supply line to at least one pressure stage of the steam turbine so as to provide a steady-state steam turbine reserve power, wherein the at least one steam turbine actuating valve is changed to a less restricted state if a network frequency decreases so as to require network frequency support. | 12-31-2009 |
20130145772 | METHOD OF OPERATING A COMBINED CYCLE POWER PLANT - A method is provided for operating a combined cycle power plant. Flue gas of a gas turbine is used for producing steam for a steam turbine. A reliable and flexible black start network restoration is achieved by: a) in island mode, supplying internal consumers by the gas turbine, the operating point of which is selected so that a minimum steam temperature is achieved; b) in island mode, the steam turbine is synchronized and ramped up to an operating point where a maximum power increase is achieved, the resulting steam turbine load change is compensated by the gas turbine; c) consumer loads are connected blockwise; d) the increase in the demanded load being provided by the steam turbine; e) the load of the steam turbine is gradually reduced increasing its load-increasing capacity; and steps c)-e) are repeated until the power plant's base load is achieved. | 06-13-2013 |
20130177388 | STARTUP METHOD FOR LARGE STEAM TURBINES - A method of controlling a steam turbine, having a controller controlling at least the position of a steam inlet valve located in a steam conduit between a steam generator and the turbine to control mass flow into the turbine, includes selecting, before beginning startup, a predefined set of startup sequences of setpoints based on a turbine status at the beginning of startup and/or a startup mode chosen by the operator, the set of startup sequences of setpoints includes parameters controlled and not controlled by the controller; using the controller to control the parameters controlled by the controller so as to progress the turbine from setpoint to setpoint in accordance with predefined set of startup sequences until reaching a release point; and at the release point, delaying moving to the next setpoint until actual setpoint values agree with predefined release point setpoint values for parameters not controlled by the controller. | 07-11-2013 |
20140239638 | METHOD FOR PROVIDING A FREQUENCY RESPONSE FOR A COMBINED CYCLE POWER PLANT - The disclosure refers to a method for providing a frequency response for a combined cycle power plant connected to an electric grid. The combined cycle power plant includes a gas turbine engine and a steam turbine engine. The steam turbine engine includes a boiler, a steam turbine, a pump, a condenser, a bypass for the steam turbine, a steam admission control valve. The steam turbine engine operates with the bypass closed or at least partly open to supply steam from the boiler to the condenser bypassing the steam turbine, and/or with the steam admission control valve at least partly open. The method comprises regulating the output load of the combined cycle power plant by regulating the steam admission control valve and/or by regulating the steam flow through the bypass in response to a frequency change of the electric grid. The output of the gas turbine can also be adjusted, such that steam generated by the boiler is sufficient to achieve the target load for the steam turbine. | 08-28-2014 |

20100108574 | SIEVE DEVICE FOR CONTROLLED SIEVING - A screening device is disclosed for a pulverulent or granular material, such as a control screen for milled products including, but not limited to, flour, middlings or semolina. The device has an inlet for material to be screened, an outlet for rejections and an outlet for undersize Furthermore, the screening device can include a screen frame with a screen fastened thereto and a base framework. The screen frame can be mounted such that it can move relative to the base framework of the screening device and be coupled to a vibrating source by which the screen frame can be made to move with vibrating movements relative to the base framework of the screening device. During operation, the screen frame can be made to move with vibrating movements whose frequency is in the range from, for example, 15 Hz to 100 Hz and whose amplitude is in the range from, for example, 0.1 mm to 6 mm. | 05-06-2010 |
