摘要： A fuel gas injector for a gas turbine engine employs a plurality of closely spaced parallel venturi tubes disposed in a pair of spaced-apart header plates. The venturi tubes are brazed to the header plates and the perimeters of the header plates are sealed to form a plenum into which pressurized gaseous fuel is supplied. Orifices lead from the plenum to throats of the venturi tubes thereby injecting the gaseous fuel at right angles into the high-velocity air stream existing at the the throats of the venturi tubes. High shear is imposed on the injected fuel for providing complete mixing with the air. The high air velocity in the throats of the venturi tubes avoids flashback and flameholding. The combined flow from the plurality of venturi tubes mixes downstream thereof to provide a uniform velocity and fuel-air mixture across the flow field. This flow field is suitable for use in a catalyst bed which may be disposed downstream of the venturi tubes.

摘要： The heater includes a jacket unit connectable to the cooling system of an internal combustion engine, the jacket unit forming a central cavity in which a catalytic burner unit is suspended by means of a bolt that extends upwardly through an upper opening in the jacket unit. Overlying the jacket unit is a perforated dome-shaped cap having a hole through which the bolt extends so that a nut applied to the upper end of the bolt clamps the perforated cap against the upper end of the jacket unit, at the same time suspending the burner unit within the jacket unit's cavity. Within the cavity is a fixedly positioned ring through which the bolt extends, the bolt having a collar that abutts the underside of the ring when the nut is fully tightened. The catalytic burner unit also includes a feed tube extending downwardly therefrom. A second perforated dome-shaped cap underlies the jacket unit having a hole through which the feed tube extends. A sleeve of catalytic material is included in the burner unit. In one instance a glow plug is employed to initially ignite the fuel supplied through the feed tube and in a second instance a heating wire is wrapped around the sleeve of catalytic material to initiate the burning action. At the upper end of the feed tube is a wick in one embodiment and a propane nozzle in a second embodiment. Provision is made for attaching the heater to a specially designed portable tank.

摘要： NO.sub.x emissions are reduced in the combustion of a fuel, containing significant amounts of NO.sub.x precursors, by carrying out the combustion in at least three, serially connected combustion zones in open communication with one another, including at least two fuel-rich zones and a last fuel-lean zone and in the presence of a combustion catalyst added to the fuel adjacent the upstream end of the first of the fuel-rich zones. SO.sub.x emissions are also reduced when burning a fuel, containing significant amounts of SO.sub.x precursors, by additionally adding a sulfur scavenger to the fuel adjacent the upstream end of the first fuel-rich zone.

摘要： A catalytic combustor for generating a mixture of steam and combustion gas is located downhole in an oil well, so that the gas mixture can be injected directly into the oil reservoir to displace heavy oils from the reservoir. There can be a single stage of catalytic combustion, or there can be a stage of thermal combustion followed by a catalytic stage. In either case the purpose of the catalyst is to drive the combustion to completion so that the gas mixture contains no soot that would plug the face of the reservoir.
