摘要:
A fuel nozzle for use with a combustion chamber defined within a gas turbine engine and a method for assembling the same are provided. The fuel nozzle includes a swirler assembly and a burner tube that is coupled to a support flange in a detachable manner such that an inner surface of the burner tube circumscribes an outer surface of the swirler assembly during fuel nozzle operation.

Methods and products for thermally degrading unwanted substances is provided which involves contacting such substances with a particulate metal composition in the presence of water and an alkali metal salt, and causing sufficient heat to be generated during such contacting to degrade the substance. The particulate metal compositions include respective quantities of particulate iron and magnesium, and optionally quantities of particulate aluminum and zinc. The compositions generate temperatures on the order of 300-550.degree. F. during such thermal degradations, along with quantities of hydrogen gas and water vapor.

A water fillable pad for positioning on the tub bottom, the top wall of said water fillable pad having a plurality of elongated air tubes serially apertured, and a compressor with a heating element delivering heated compressed air through a manifold tube to said air tube so heated bubbles rise and agitate the tub water around the bather. The water fillable pad has a hingedly connected air inflatable back rest and an air inflatable side pad which drapes over the tube side wall and down to the float surface. A foot drain tray assembly is mounted to the free side edge of the air inflatable side pad member on which a bather can stand after finishing his bath. The foot drain tray assembly can be tucked under the water fillable pad when arching the air inflatable side pad member, thus forming a dome for the bather and a capture space for the discharged air bubbles.

A fuel nozzle configured to channel fluid toward a combustion chamber within a gas turbine engine and a method for assembling the same are provided. The fuel nozzle includes a first hollow tube fabricated from a first material that has a first coefficient of thermal expansion and a second tube fabricated from a second material that has a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. The second tube is coupled within the first tube such that the first tube substantially circumscribes the second tube, and the second tube thermally expands approximately at a same rate as the first tube during fuel nozzle operation.
摘要:
A system for the destruction of volatile organic compounds while generating power. In a preferred embodiment the system comprises a combustor and a reaction chamber connected to an exit of the combustor. A primary inlet to the combustor supplies a primary fuel to the combustor. A secondary fuel, comprising air and an amount of one or more volatile organic compounds, is supplied to a compressor, which compresses the secondary fuel and directs the secondary fuel to the combustor and the reaction chamber. The system is suitably configured to enable the stoichiometric reaction of the two fuels in a manner sufficient to destroy the volatile organic compounds contained in the secondary fuel and power a turbine engine connected to an exit of the reaction chamber.

An interrupt system for a circuit includes a single-pole, double-throw selector switch. The circuit may comprise an ignition circuit including a coil and a distributor normally innerconnected by a distributor wire. The selector switch has a first terminal, a second terminal connected to the coil and a third terminal connected to the distributor. The selector switch is movable between a first position connecting the first and second terminals and a second position connecting the second and third terminals. A delay switch is connected to the first and third terminals and has a normally closed position. The delay switch opens automatically in response to electrical current flowing therethrough.

A swirl vane is independently connectable to a central hub assembly of a gas turbine. The swirl vane includes a structural body and at least one fuel delivery passage including a corresponding at least one fuel port defined within the structural body. At least one connecting tab is cooperable with the structural body and is connectable to the central hub assembly.
