Patent number: 7841183Abstract: A method of operating a delivery apparatus and a delivery apparatus are disclosed for the continuous delivery of a liquid. The method and the apparatus are suitable in particular for use in a water injection system for injecting water into a main flow of a gas turbine. The delivery apparatus includes a plurality of delivery devices connected parallel to one another. In a first method step, the delivery devices of the delivery apparatus are assigned to at least two delivery device groups. The delivery device groups with the respectively assigned delivery devices are then switched to the active state from the rest mode in a rolling manner in time segments in order to deliver the liquid mass flow. In each case at least one delivery device is therefore operated in the rest mode in a rolling sequence per time segment.Type: GrantFiled: October 4, 2006Date of Patent: November 30, 2010Assignee: Alstom Technology LtdInventors: Carlos Jimenez Haertel, Stefan Oesterle, Carsten Reumschuessel, Sasha Savic

Patent number: 7832192Abstract: A system for the atomization of liquid is arranged on the intake duct of a gas turbo set. This atomization system comprises a number of nozzle tubes with atomizer nozzles, switching valves for selective action upon the nozzle tubes by liquid and a pump for conveying the liquid to be atomized. According to the invention, the pump is connected to a variable-speed drive. The switching valves are preferably designed as proportional valves. In a corresponding regulating circuit, this makes it possible to limit pressure gradients in the atomization system and consequently to avoid hammers.Type: GrantFiled: March 1, 2006Date of Patent: November 16, 2010Assignee: Alstom Technology LtdInventors: Carlos Jimenez Haertel, Stefan Oesterle, Carsten Reumschuessel, Sasha Savic
