US Patent:

6367239, Apr 9, 2002

Filed:

Dec 9, 1998

Appl. No.:

09/207952

Inventors:

Curtis L. Brown - Cincinnati OH
Douglas M. Fortuna - Cincinnati OH
Gilbert H. Badeer - Loveland OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 330

US Classification:

60 3905, 60 3955, 60742, 60 39463

Abstract:

A fuel delivery system and method for operating a dual fuel and steam turbine engine that utilizes gas fuel at the engine start phase through a combination of gas and liquid fuel circuits. Gas fuel initially flows through the liquid fuel circuits to a dual fuel and steam nozzle. A boiler connected to the system generates steam, and the steam is supplied to the nozzle to raise the fuel pressure to an acceptable range. The gas fuel is injected into both the liquid and gas fuel circuits and the engine can then operate on either gas or liquid fuel, or any combination thereof.

Douglas M. Fortuna - Cincinnati OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02G 726

US Classification:

60 3906

Abstract:

An operating system includes a fuel and control sub-system which includes a main gas circuit, a start gas circuit, a dual fuel nozzle, and a plurality of metering valves. The fuel and control sub-system is configured to transition the operation of the engine from operating with a start gas having a high heating value to using a main gas having a low heating value. The sub-system is further configured to inject water into the gas turbine and permits a user to adjust an overall fuel heating value to improve flammability limits and avoid regions of combustor acoustics.

Appl. No.:

09/354274

Inventors:

Stephen R. Payling - Cincinnati OH
Robert P. Coleman - Fairfield OH
Curtis L. Brown - Cincinnati OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 330

US Classification:

60 3953

Abstract:

Precompressor and pre-booster water spray injection apparatus and methods are described. In an exemplary embodiment, a plurality of nozzles are configured so that water injected into the gas flow to the high pressure compressor provides substantially uniform radial and circumferential temperature reductions at the outlet of the high pressure compressor.

Appl. No.:

09/354275

Inventors:

Stephen R. Payling - Cincinnati OH

Curtis L. Brown - Cincinnati OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 330

US Classification:

60 393, 60 3953

Abstract:

Methods and apparatus for injecting water into a turbine engine are described. In one embodiment, water injection apparatus is provided for injecting water into the gas flow through the engine, e. g. , at a high pressure and/or low pressure compressor inlet. The water injection apparatus includes a plurality of nozzles arranged so that water injected into the gas flow by the nozzles results in substantially uniformly reducing the temperature of the gas flow at the high pressure compressor outlet.

Inventors:

Mark Stephen Rocklin - Wyoming OH
Nicholas Damlis - Cincinnati OH
Curtis Lee Brown - Cincinnati OH
Robert Paul Coleman - Fairfield OH
James William Stegmaier - West Chester OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 330

US Classification:

60775

Abstract:

A method is provided for operating a gas turbine engine that includes a high pressure compressor and a water injection apparatus for injecting water into a flow of the engine upstream from the high pressure compressor. The method includes the steps of operating the engine without injecting water into the gas flow of the engine, injecting water at a first flow rate into the gas flow for power augmentation once engine full power is about reached, and injecting water into the engine at an increased second flow rate for evaporative cooling of engine components downstream from the high pressure compressor.

International Classification:

F02C 716

US Classification:

60 3953, 60785

Abstract:

Control systems and methods for controlling injection of water into a turbine engine are described. In an exemplary embodiment, the water injection system includes a plurality of nozzles for injecting water into a gas flow through the engine, a water source, a water manifold, a water supply line extending from the water source to the water manifold, a water metering valve for controlling flow through the water supply line, an air manifold, an air flow pipe coupled to the high pressure compressor and to the air manifold, a plurality of air feeder tubes extending from the air manifold to the nozzles, and a plurality of water feeder tubes extending from the water manifold to the nozzles.

International Classification:

G06F 1100
G05D 706

US Classification:

36443102

Abstract:

In a two-channel control system for a gas turbine engine, the occurrence of a fault in the engine causes the control system to switch from one channel to the other. If it is found that neither channel is operative, the invention terminates fuel delivery, thus stopping the engine.
