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: Methods and systems for imparting corrosion resistance to gas turbine engines are disclosed. Existing and/or supplemental piping is connected to existing compressor section air extraction and turbine section cooling air piping to supply water and anti-corrosion agents into areas of the gas turbine engine not ordinarily and/or directly accessible by injection of cleaning agents into the bellmouth of the turbine alone and/or repair methods. An anti-corrosion mixture is selectively supplied as a liquid-steam mixture to the compressor and/or the turbine sections of the gas turbine engine to coat the gas turbine engine components therein with a metal passivation coating which mitigates corrosion in the gas turbine engine.

Abstract: Systems and methods for mitigation of hot corrosion in steam injected gas turbine. In one embodiment, a steam injection system can provide for automatic injection of steam in a gas turbine for NOx abatement and power augmentation. The system can obtain indications as to whether the steam to be injected meets the requirements of the gas turbine in terms of purity and quality. If the quality or purity is not adequate, steam the injection into the combustor or compressor discharge casing (CDC) is automatically inhibited. The system may also monitor the dynamic pressure oscillations inside the combustor. The system may modulate steam flows modulates to enhance the total steam flow while maintaining the dynamic oscillations within acceptable limits.
