An improved exhaust system and catalytic converter element for a diesel engine wherein the improvement comprises: holding means for restricting the movement of catalytic converter elements in an overhead exhaust manifold; an improved catalytic converter element having at least one retaining rod extending through the catalyst substrate and/or having at least one retaining lip projecting into the substrate; a stabilizer projecting from the cover for the element insertion slot for receiving an end portion of the catalytic converter element to restrict the movement of the converter element in the exhaust manifold; perforated flow distribution elements provided upstream of the catalytic converter elements; and/or vertical coupling manifolds which each receive exhaust from a pair of engine cylinders and then deliver the combined exhaust stream to a separate one of the inlet openings in the bottom of the overhead exhaust manifold.

Catalytic converter system and element for diesel engines

An improved exhaust system for a diesel engine and an improved overhead exhaust manifold segment therefore wherein the improvement comprises a plurality of catalytic converter elements removably positionable in the overhead exhaust manifold over the outlet ends of a series of exhaust port legs extending upwardly to the bottom of the overhead exhaust manifold from the cylinder exhaust ports.

Catalytic converter system for diesel engines

An industrial catalytic converter and a removable catalyst element therefor wherein a solid extension is secured on the catalyst element such that, when the catalyst element is positioned in the converter housing, the solid extension will project into the element insertion channel of the housing in a manner effective to at least partially block the flow of exhaust gas around the catalyst element.

Catalytic converter and catalyst element therefor

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.

Catalytic combustor cooling tube vibration dampening device

A catalytic combustor includes a plurality of rectangular, tubular subassemblies having the catalyst coating on their outside surfaces. The subassemblies are held in spaced relationship within channels in support walls so that the catalyst coated surfaces of adjacent subassemblies define a catalyst-coated channel, and the interior of the tubular subassemblies defines uncoated channels. This structure permits precise location and support for the various subassemblies, provides wide flexibility in selecting the number and size of catalyst coated subassemblies, and provides for multiple possible flow paths for cooling air and fuel-air mixture through the catalytic combustor.

Catalyst support structure for use within catalytic combustors

A catalytic combustor ( ) for a gas turbine engine ( ). A fuel-air mixture ( ) is reacted on a catalytic surface ( ) of a catalytic heat exchanger module ( ) to partially combust the fuel ( ) to form heat energy. The fuel-air mixture is formed using compressed air ( ) that has been pre-heated to above a reaction-initiation temperature in a non-catalytic cooling passage ( ) of the catalytic heat exchanger module ( ). Because the non-catalytic cooling passages ( ) provide the necessary pre-heating of the combustion air, no separate pre-heat burner is required. Fuel ( ) is added to the pre-heated air ( ) downstream of the non-catalytic cooling passage ( ) and upstream of the catalytic surface ( ), thereby eliminating the possibility of flashback of flame into the cooling passages ( ). Both can-type ( ) and annular ( ) combustors utilizing such a combustion system are described.

Cross flow cooled catalytic reactor for a gas turbine

A catalytic combustor assembly which includes, an air source, a fuel delivery means, a catalytic reactor assembly, a mixing chamber, and a means for igniting a fuel/air mixture. The catalytic reactor assembly is in fluid communication with the air source and fuel delivery means and has a fuel/air plenum which is coated with a catalytic material. The fuel/air plenum has cooling air conduits passing therethrough which have an upstream end. The upstream end of the cooling conduits is in fluid communication with the air source but not the fuel delivery means.

Piloted rich-catalytic lean-burn hybrid combustor

A method and system for combusting a liquid fuel stream in a diffusion flame combustor by spraying the liquid fuel stream into a steam flow to produce a fuel/steam flow with atomized liquid fuel therein. The fuel/steam flow is further mixed before being combusted in the diffusion flame combustor to produce at least a first portion of an emission stream therefrom.

Diffusion flame combustor with premixing fuel and steam method and system

A combustor with a flashback arresting system for producing a hot gas by burning premixed fuel and compressed air having fuel/air premixing passages, each of the passages having an inlet end and a discharge end. Disposed immediately upstream of the inlet ends of the fuel/air premixing passages is a fuel manifold for delivering fuel to the passages. Fuel lines with fuel flow control valves connect the fuel manifold with a fuel supply. The flashback arresting system has one or more optical flame detectors with a light receiving portion located upstream of the discharge ends of the fuel/air premixing passages and oriented toward at least a portion of at least one of the fuel/air passages. The flame detectors are responsive to receiving light from a flashback by its light receiving portion by transmitting an output signal to a control system. The control system controls the fuel flow control valves and responds to the output signal by adjusting the fuel flow control valves to eliminate the flashback.
