The present application provides a pulse filtration system for use with a compressor of a gas turbine engine. The pulse filtration system may include a pulse filter, a compressed air system in communication with the pulse filter, and a hydrophobic filter bag surrounding the pulse filter in whole or in part.

Inlet air filtration system with self-cleaning hydrophobic filter bag

An on-line wash system for a compressor including: a nozzle including a flow passage for wash liquid, wherein the flow passage is configured to be coupled to a source of a wash liquid and includes a discharge outlet arranged to project the wash liquid into a stream of working fluid for the turbomachine; an electrode proximate to the flow passage of the nozzle, wherein the electrode is configured to form an electrical field sufficient to charge the wash liquid flowing through the passage and the charge applied to the wash liquid is of a first polarity, and a surface of the compressor charged with the first polarity, wherein the surface is exposed to the stream of working fluid and downstream of the nozzle.

Gas turbine on-line water wash system and method

An inlet system for a gas turbine includes an inlet air duct; a silencer disposed in the inlet air duct, the silencer including a plurality of panels with spaces between the panels; and a conduit with orifices disposed to inject inlet bleed heat into each of the spaces. A method of conditioning inlet air for a gas turbine includes flowing air through spaces between panels of a silencer in an inlet air duct of the gas turbine, and injecting inlet bleed heat through orifices and into each of the spaces.

A cooling enclosure for a valve includes an elongated housing body having a pair of housing portions and a pair of removable end plates, the pair of housing portions separable along at least one longitudinally-extending seam. Fastener devices are provided for securing the pair of housing portions engaged along the at least one longitudinal extending seam. One or more apertures are provided for accommodating a like number of valve fittings, and cooling air inlet and outlet openings are also provided in the housing body for supplying and removing cooling air to the housing body.

Air cooling apparatus for a purge valve

A fuel injector for injecting fuel into a gasifier includes a mating end including a nozzle portion and a first flange fixedly coupled to the mating end and having a first receiving hole there through and including a first diaphragm disposed therein. The injector also includes a fuel transmission nozzle displaced at least partially within the mating end and passing through the first receiving hole arranged and configured such that a secondary oxygen channel exists between the fuel transmission nozzle and the mating end, the fuel transmission nozzle being fixedly coupled to the first diaphragm and further including a fuel inlet for receiving fuel for introduction into the gasifier.

Fuel injector gassifer nozzle having adjustable annulus

A method and apparatus for monitoring and measuring gas concentrations in combustor applications is provided, wherein the apparatus is a gas sensor having a plurality of electrodes cooperating with a single electrolyte cell for detecting the presence and concentration of gaseous components of a flue gas. A voltage is generated based on the flow of ions caused by differing gas concentrations as detected by electrodes across the electrolyte. The change in voltage is correlated and is used to determine the concentration of detected gases, such as combustible gases, nitric oxides, carbon monoxide, etc., contained in the flue gas. The combustor operation may then be optimized to enhance efficiency and minimize undesired gas concentrations in the flue gas in a desired fashion. A calibration gas may be introduced to calibrate the apparatus and a reference gas may be provided to an electrode as a basis for correlating the concentrations of the gases.
