    Abstract: A system and method is provided that improves the under frequency response of gas turbines by providing a fast-response power augmentation system. The system includes a tank storing a blended mixture of motive fuel such as ethanol or methanol and demineralized water in a predetermined ratio that is provided as a diluent to be injected into the compressor bellmouth, the Compressor Discharge Chamber (CDC), and/or the combustion system via one to three dedicated circuits. To achieve the instantaneous injection of the diluent at the correct pressure and for the appropriate duration to meet the needs of the gas turbine Grid compliance mandate, an accumulator is used as the motive force to drive the augmentation fluid in the dedicated circuits. The injected diluent is microprocessor controlled to either be simultaneous into all three circuits or is sequenced based on a determination of the best turbine control and performance.

    Abstract: A closed circuit fuel heating system is provided for heating at least two types of fuel. The heating system includes a heat transfer subsystem disposed in a gas turbine system exhaust. A first heat exchange subsystem is coupled to a first fuel source and the heat transfer subsystem. The first heat exchange subsystem is provided with a control component for controlling a flow of a working fluid through the first heat exchange subsystem. A second heat exchange subsystem may be coupled to a second fuel source and the heat transfer subsystem. The second heat exchange subsystem is provided with a control component for controlling a flow of the working fluid through the second exchange subsystem. A subsystem for controlling the temperature of the working fluid is also provided.
