A catalytic section of a combustor is formed from a spaced tandem array of corrugated panels. The exterior top and bottom surfaces of the panels are coated with a catalyst and the space between panels defines a passage for a fuel-rich/air mixture. The interior of the corrugated panels define cooling air passages for maintaining the catalyst and substrate on which it is formed, at acceptable temperatures.

A gas turbine combustion system and method used for generating electrical power includes a compressor that receives and compresses air. A first stage turbine nozzle is flowise connected to the compressor and receives a portion of the compressed air from the compressor within a first air flow. A torus configured combustion chamber is positioned around the first stage turbine nozzle and receives a portion of the compressed air from the compressor within a second air flow that is passed through the combustion chamber where air and fuel are mixed and combusted. The air is discharged at the first stage turbine nozzle to mix with the first air while achieving a dry low NOx combustion.

A gas turbine engine ( ) includes a catalytic oxidation module ( ). The catalytic oxidation module includes a pressure boundary element ( ); a catalytic surface ( ); and an opening ( ) in the pressure boundary element to allow premixing of the fluids before the fluids enter a downstream plenum. In an embodiment, the pressure boundary element includes a catalyst-coated tube ( ) having holes ( ) formed therein to allow mixing across the tube. In another embodiment, the pressure boundary element includes a tubesheet ( ) having a first fluid passageway intersecting a second fluid passageway to premix the fluids upstream of the outlet end of the tubesheet. In yet another embodiment, the catalytic oxidation module includes an upstream tubesheet ( ) for mounting a tube inlet end ( ) and a downstream tubesheet ( ) for mounting a tube outlet end ( ) so that the tube is slidably contained there between.

An electrostatic precipitator especially useful in separation of particulate matter from gas streams under high pressure and high temperature conditions has a collection electrode that is formed of a porous material and means to effect a flow of gas from the clean side of the electrode, through the porous electrode, to dislodge solids collected on the electrode for cleaning purposes. A chamber is formed on the clean side of the collecting electrode and a jet pulse of gas is charged to the chamber, which pulse of gas is distributed through the porous collecting electrode to dislodge the solids from the collecting surface thereof. In one embodiment, a porous flexible member is disposed adjacent the collecting surface of the collecting electrode and the solids are deposited thereon and dislodged therefrom by passage of a gas through the porous collecting electrode.

An apparatus and method for removing particulate contaminants, and optionally gaseous contaminants, from a hot gaseous stream where a vessel is provided containing a fluidized bed zone and the gases are passed through the fluidized bed zone containing a fluidized bed of granular media prior to passage of a major portion of the gas through a plurality of first hollow, ceramic, barrier filter elements at least partially disposed in the fluidized bed, and a minor portion thereof through a plurality of second hollow, ceramic, barrier polishing filter elements removed from the fluidized granular media. The plurality of first filter elements are scoured by the granular media to remove collected deposits while fine particulates collected on the plurality of second filter elements are removed by back flushing of a gas therethrough.

A filtering unit for filtering particulates from high temperature gases uses a spiral ceramic spring to bias a ceramic, tubular filter element into sealing contact with a flange about an aperture of a metallic tube sheet. The ceramic spiral spring may contact the upper edge of the filter element and be restrained by a stop member spaced from one end of the tube sheet, or the spring may contact the bottom of the filter element and be restrained by a support member spaced from the opposite end of the tube sheet. The stop member and support member are adjustably secured to the tube sheet. A filtering system uses the ceramic spiral spring to bias a plurality of ceramic, tubular filter elements in a respective plurality of apertures in a tube sheet which divides a vessel into upper and lower enclosed sections.

A filter system wherein a hollow tubular member having an imperforate wall with a plurality of slots therein is coaxially positioned within a perforated mandrel that supports a ceramic bag filter. Gases to be filtered pass through the bag filter and deposit particulate matter thereon, enter a chamber between the perforated mandrel and the hollow tubular member, and are directed through the slots into the interior of, and are discharged from an open end of the hollow tubular member. Vapor phase contaminants in the gas can also be removed by providing a bed of solid absorbent material in the hollow tubular member such that the gas contacts the solid absorbent material and the vapor phase contaminant is removed prior to discharge of the gas from the open end of the hollow tubular member.

A filter system wherein a cylindrical shell having open ends and a gas-impervious wall with means for supporting a filter tube coaxially within the shell to form an annular chamber therebetween has means for securing the filter tube to the other open end, such that gases from the enclosure must pass through the filter tube into the annular chamber and then out of the cylindrical shell. A jet pulse means is provided to provide a jet pulse of fluid to the annular chamber to flex the filter tube inwardly to dislodge solids collected on the interior surface of the filter tube.
