Abstract:
A method and system for enhancing power generated by a gas turbine system. The system may include a turbine inlet cooling system and a wet compression air fogging system. Air entering the gas turbine system is cooled by the turbine inlet cooling system and the wet compression air fogging system. The wet compression air fogging system may increase the mass flow rate of the air entering the gas turbine system at the compressor.
Abstract:
The present invention discloses a novel apparatus and methods for augmenting the power of a gas turbine engine, improving gas turbine engine operation, and reducing the response time necessary to meet changing demands of a power plant. Improvements in power augmentation and engine operation include systems and methods for preheating a steam injection system.
Abstract:
A method of augmenting power output by a gas turbine engine includes channeling fuel into the gas turbine engine at a predetermined fuel flow rate to generate a first power output. Steam is then injected into the gas turbine engine at a first steam flow rate, and a firing temperature bias is determined based at least on the first steam flow rate. The predetermined fuel flow rate is then adjusted based on the determined firing temperature bias such that the gas turbine engine generates a second power output greater than the first power output.
Abstract:
A combined water-wash and water injection cooling system for a gas turbine engine including a water delivery system, an air delivery system, and a controller configured to couple to the gas turbine engine, the water delivery system, and the air delivery system to access and execute one or more routines. The water delivery system includes one or more spray nozzles to spray water upstream and directly in front of a compressor of the gas turbine engine. The air delivery system is configured to provide air from the compressor to the water delivery system so that the one or more spray nozzles spray atomized water into the compressor of the gas turbine engine during a cooling mode to cool the compressor. During an on-line water wash mode, air from the air delivery system to the water delivery system is turned off to enable the one or more spray nozzles to spray non-atomized water into the compressor of the gas turbine engine to wash the compressor.
Abstract:
Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.
Abstract:
A system and method include a nozzle configured to inject water into a gas turbine at a specified water flow rate. An effluent stream of the gas turbine includes a gas turbine effluent stream including a first emission level. A secondary emissions control apparatus is in fluid communication with the gas turbine effluent stream. An output stream of the secondary emissions control apparatus can include a second emissions level below a specified emissions output threshold. The method and system can reduce the amount of water over time that is introduced into the gas turbine based on the threshold emissions reduction capability of the secondary emissions control apparatus.

Abstract:
A gas turbine for a gas and steam turbine plant and method for operating a gas turbine is provided. The gas turbine includes a cooling system for cooling inlet air taken from compressor extractions or compressor discharge and introduced to the turbine(s) and/or combustor(s) of the gas turbine which is adapted for flexible operation in a combined cycle application as well as a simple cycle application. The cooling system includes at least a water/steam cooled cooling air cooler for use in a normal combined cycle application. The gas turbine is provided with at least one second cooling air system arranged in a bypass which is operable instead of or parallel to the water/steam cooled cooling air cooler for use in particular in a simple cycle application operation of the gas turbine.
