International Classification:

B08B009/00

US Classification:

134 2218, 134 6, 134 8, 134 221, 134 24, 134 34, 134 42, 134169 R, 1510409, 15104095, 1510416, 1510405, 15211, 15301, 15302, 15304, 153121, 153122, 153161, 15406

Abstract:

The compressor cleaning system includes a track mounted about the inlet of the compressor. A circumferential position assembly mounts an insertion drive assembly which is driven about the track into selected circumferential positions. The insertion drive assembly carries a manipulator arm assembly mounting at its distal end a cleaning head. By using pairs of control cables, the proximal yaw, pitch and distal yaw sections of the manipulator arm can be moved to weave the cleaning head past the multiple stages of blading to locate the cleaning head adjacent a selected blade. By repeated extension and retraction of the cleaning head relative to the compressor inlet and about the compressor blades, each blade can be cleaned without disassembly of the compressor casing or removal of the rotor.

Abstract:

A system for performing gas turbine system adjustments includes a server installed on a computer, the server coupled to a gas turbine engine control system and configured to transmit data indicative of an operating state of a gas turbine engine, and a client application including a database, the client application configured to receive the gas turbine operating state data transmitted by the server, and enable a user to analyze the gas turbine operating data to determine a desired gas turbine operating state, wherein the desired operating state is communicated to the gas turbine engine control system to facilitate adjusting at least one gas turbine combustion control system operating parameter based on the desired gas turbine operating state.

International Classification:

F01K 734

US Classification:

60653

Abstract:

In a combined cycle power plant comprising a steam turbine and gas turbine connected through a heat recovery steam generator, the start-up mode for a steam turbine is based upon the shell metal temperature of the steam turbine. In some combined cycle plants, the output of the gas turbine is reduced so as to more closely match the output steam temperature of the heat recovery steam generator to the steam turbine metal temperature. This arrangement can be disadvantageous for several reasons and so it is proposed that a spray attemperator or desuperheater be incorporated between the heat recovery steam generator outlet and the steam turbine inlet. Moreover, control means are indicated for controlling the fluid input into the attemperator.

Abstract:

In a liquid cooled thyristor stack in which a plurality of disk thyristors are stacked between a plurality of cold plates such that each thyristor has a cold plate on either side thereof, relatively rigid tubular connectors are provided which extend between the cold plates and an associated coolant header. The connectors are provided at first ends with reduced diameter portions for receiving electrically non-conductive insulating bushings which are, in turn, received within ports of the coolant header.
