20140126998 | Compressor Bellmouth with a Wash Door - The present application thus provides a compressor wash system for use about a bellmouth of a compressor of a gas turbine engine. The compressor wash system may include a bellmouth wash nozzle positioned about the bellmouth of the compressor and a wash door assembly positioned about a lower half of the bellmouth such that the wash door assembly may be closed when the bellmouth wash nozzle is activated. | 05-08-2014 |
20140137564 | Mitigation of Hot Corrosion in Steam Injected Gas Turbines - 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. | 05-22-2014 |
20150202561 | AIR FILTER WITH FOLDED PLEATS - An air filter includes a filter material having a plurality of pleats, where each of the pleats includes a primary section and a folded section. The folded section is initially folded over at least a portion of the primary section such that the pleat has an initial pleat height. The folded section is configured to unfurl from being folded over the primary section based on a pressure differential between opposite sides of the filter material. | 07-23-2015 |
