Abstract:
Provided is an outer casing having a bottomed tube shape, the casing having a cooling water supply port, and a cooling water discharge port, and being inserted into a high-temperature furnace; an inner casing having a bottomed tube shape inserted into the outer casing; an imaging unit that is disposed in the inner casing which captures an image of the exterior of the outer casing; and partition members that are between an inner surface of the outer casing and an outer surface of the inner casing which define a first flow channel, a second flow channel, and a communicating channel for communicating the first flow channel and the second flow channel between the bottom of the outer casing and the partition members.
Abstract:
Methods, systems, and devices are disclosed for chemically activating a fuel for injection and ignition in a combustion engine. In one aspect, a method to initiate combustion includes transforming an interim fuel substance into constituents including radicals, the interim fuel substance formed by a chemical conversion using a fuel, in which the interim fuel substance has a lower ignition energy than that of the fuel, injecting the constituents into a combustion chamber of an engine, and providing a gaseous fluid including oxidants in the combustion chamber to react with the constituents in a combustion reaction, in which the combustion reaction of the constituents occurs at a reduced energy than that of a combustion reaction of the fuel substance.
Abstract:
A door assembly for an oven comprises an inner frame, a first glass panel and a first pair of brackets coupled with the inner frame and compressively retaining the first glass panel against the inner frame.
Abstract:
A component sensing system for monitoring the condition of ceramic tiles in a combustion chamber of a gas turbine engine. The sensing system includes an optical fiber that is mounted to the component being monitored, for example, the ceramic tiles in the gas turbine combustion chamber. The optical fiber can be formed in any suitable orientation or configuration, such as a meandering or serpentine orientation. The fiber is optically coupled to a Brillouin signal analyzer that provides an optical pulse to the sensing section of the fiber and detects Brillouin backscattering from the fiber as the pulse travels along the fiber. The frequency of the Brillouin backscattering signal is monitored relative to the distance along the sensing section of the fiber. A rise in temperature at a location of the fiber shows up in the analyzer as an increase in frequency of the backscattered signal.
Abstract:
A cooling system for air ports and other ports in furnace walls includes a cooling medium pumping system and ports provided with a cooling medium piping or channels inside the metallic port material. The liquid flow generated by the cooling medium system cools the ports. The ports are constructed of a casting material, and the ports are provided with a cooling liquid flow, which passes in a piping or pipings or channels inside the casting material of the ports.
Abstract:
A system is provided to monitor a structure within an outer casing of a gas turbine engine. The system may comprise an optical fiber bundle, a fiber bundle palette and a camera palette assembly. The optical fiber bundle may have first and second ends. The first end is adapted to pass through a bore in the outer casing of the gas turbine engine so as to be positioned adjacent the structure within the gas turbine engine casing to be monitored. The fiber bundle palette is adapted to be located outside of the engine casing to receive the second end of the optical fiber bundle. The camera palette assembly comprises a fixture movable relative to the fiber bundle palette and a first camera mounted to the fixture. The first camera is adapted to be positioned adjacent to the second end of the optical fiber bundle so as to receive electromagnetic radiation received by the first end of and transmitted through the optical fiber bundle.
Abstract:
A powered multi-fuel burner has a burner assembly which utilizes an air aspirated nozzle. An air compressor provides air to the air aspirated nozzle and to a fuel-holding tank where the fuel within the tank is put under air pressure thereby to enhance its flow to the air aspirated nozzle. A bleed valve is positioned between the air compressor and the fuel thank thereby to increase or decrease the air pressure within the fuel tank. By increasing and decreasing the air pressure within the tank, the burner can produce heat over a range of operation.
Abstract:
A burner has a burner tube and a nozzle holder mounted in one end of the burner tube. An igniter is positioned within the nozzle holder and acts to ignite any of the multi-liquid fuels which may be used with the burner. A nozzle emits atomized liquid fuel under the venturi effect of the nozzle with compressed air being supplied to the nozzle. Primary air holes extend circumferentially around the nozzle holder to admit air radially which passes directly to the burner tube. Secondary air holes extend around the inside circumference of the burner tube on the secondary air injection plate and admit air axially to the burner tube.
Abstract:
Infrared emitting surfaces such as a smelt bed in a Kraftchemical recovery boiler can be monitored by a closed circuit infrared camera equipped with a 1.5 micrometer edge filter. The camera power supply is isolated from the heat sensitive camera pick up tube and yoke assembly. This separation also makes it easier to mount and dismount the tube on and off of the boiler. The tube is contained in a housing which is supported by bearings which are slidable on rods attached to the boiler wall. This attachment ensures that the image produced will not change with mounting and dismounting the camera. An image change would result in a waste of smelt bed chemicals.
