Abstract: A gas turbine engine (10) includes a catalytic oxidation module (28). The catalytic oxidation module includes a pressure boundary element (30); a catalytic surface (32); and an opening (34) 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 (58) having holes (68) formed therein to allow mixing across the tube. In another embodiment, the pressure boundary element includes a tubesheet (44) 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 (86) for mounting a tube inlet end (73) and a downstream tubesheet (78) for mounting a tube outlet end (72) so that the tube is slidably contained there between.

Abstract: 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.

Abstract: A dampening device for suppressing vibrations of a tube assembly in a catalytic combustor which includes, a plurality of closely oriented, parallel tubes with each tube having at least one expanded region and at least one narrow region. The expanded regions being structured to contact at least one adjacent tube, thus providing support and minimizing degradation of the joint connecting the tubes to the tube sheet, and degradation of the tubes themselves. Such degradation can result from vibration due to flow of cooling air inside of the tubes, flow of the fuel/air mixture passing over the tubes transverse and longitudinal to the tube bundle, and/or other system/engine vibrations.

Abstract: A resonator module for a combustion turbine power plant, where the combustion turbine power plant defines a flow path. The resonator module includes a first member, an a second member. The first member has a size substantially smaller than the diameter of said flow path and a plurality of openings therethrough. The openings are in fluid communication with the flow path. The second member has a size generally equal to said first member. The second member is in a generally spaced relation to the first member and encloses a volume of gas between the first and second members.

Abstract: A universal tool for the weld inspection of tubular objects such as reactor vessels is disclosed. The tool is constructed from an array of transducers mounted in groups for common inspection of a particular weld volume. The individual transducers, as well as the groups, are arranged in a compact assembly for minimizing the overall dimensions of the tool and its corresponding weight. The transducers are arranged in a manner which permits inspection of tubular objects having different radii of curvature and corresponding different diameters with a single tool without the need of having to individually adjust the orientation angles of the transducers.

Abstract: A powered loading system is disclosed for loading and unloading a heavy load-carrying module onto a vehicle for transport. The module is supported for movement on casters and, additionally, it includes rollers and a slotted probe member. The transport vehicle for receiving the module includes ramp members for engaging the rollers on the module. A motor on the vehicle is coupled to a jackscrew which is attached to a movable block member. A hook member is supported on the block for displacement in an arcuate path normal to the ground plane. With the rollers on the module in position on the ramp members and deplacement impending, when the motor is actuated, the hook member engages and disengages with the slotted probe member for raising and lowering the module for, respectively, loading and unloading the module on the transport vehicle.
