A disposal system for the processing of solid waste devices to recycle materials located within the devices and recover, reuse and recycle such materials. Such system may include a primary chamber and secondary chamber, attached preferably by use of one or more exhaust ducts, and a secondary chamber exhaust duct. The solid waste devices may include any type of waste, such as electronics waste, medical device waste, and the like.

A hybrid stepping motor has a connector housing formed integrally with an insulator having an upper insulator and a lower insulator. The hybrid stepping motor includes a stator core and output terminals concentrically disposed outside the stator core. A wiring pattern serving as the output terminals has connector pins and land portions disposed eccentrically with respect to one another. The land portions are formed on an outer edge side of the wiring pattern. A surface, which is an uppermost surface of the wiring pattern, is located below a lowermost surface, in which jumper wires and lead wires pass, of the lower insulator. The lead wires are pulled out from a lower side, and are pulled out to guiding grooves.

A method for controlling the Btu content of a flare gas to combusted in a flare stack comprising a flare tip is provided. The method includes, introducing a first gas stream including nitrogen to be flared, the first gas stream having an initial Btu content, providing a supplemental fuel gas stream, and combining the first gas stream with the supplemental fuel gas stream, thereby obtaining a flare gas stream having a final Btu content measured at the flare tip.

A cyclone temperature control system for a cyclone of a decoating system includes a controller, a gas mover, and a control valve that is movable between a fully open position and a closed position. A method of controlling the temperature of the cyclone includes determining a cyclone temperature of the cyclone and comparing the cyclone temperature to a cyclone threshold temperature. The method also includes opening the temperature control valve and directing at least some heated gas from an afterburner of the decoating system to mix with exhaust gas from a kiln of the decoating system to increase the temperature of the exhaust gas if the cyclone temperature is less than the cyclone threshold temperature.

The present invention relates to a thermal treatment device comprising a primary chamber (204) for receiving waste material (230) to be combusted, the primary chamber having a hearth (207), a transport system (206) arranged for transportation of waste material across the hearth, a mixing chamber (220) in fluid communication with the primary chamber (204); a secondary chamber (208) in fluid communication with the mixing chamber (220), and material introducing means (229) for introducing waste material (230) into the primary chamber, wherein the material introducing means (229) comprises a valve (202) for controlling air flow there-through.

According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.

The present invention relates to a ducting system (100) for conveying a flow of a gaseous feed (110) comprising a combustible component from an inlet to at least one combustion module (12), the ducting system (100) utilising a combination of a sensor (C0) for measuring the concentration of the combustible component in the gaseous feed (110), a flame detector (F0, F1, F2, F3, . . . , Fn) a shut-off valve (6) and a flame arrestor (5) located in a flow path of the gaseous feed upstream of the shut-off valve (6) such that a measurement of a concentration of combustible material in the gaseous feed over a specified concentration by the sensor (CO) causes the shut-off valve (6) to be configured to the closed position for preventing flow of a gaseous feed comprising a combustible mixture of the combustible component from reaching an ignition source and/or detection of flame by the flame detector (F0, F1, F2, F3, . . . , Fn) causes shut-off valve (6) to be configured to the closed position for attenuating propagation of a flame towards the inlet.

The present disclosure generally relates to systems and methods for the combustive abatement of waste gas formed during the manufacture of semiconductor wafers. In particular, the systems described herein are capable of combusting air-polluting perfluorocarbons, including those having high greenhouse gas indexes such as hexafluoroethane (C.sub.2F.sub.6) and tetrafluoromethane (CF.sub.4), as well as particulate-forming silicon dioxide precursors, such as silane (SiH.sub.4) and tetraethoxysilane (Si(OC.sub.2H.sub.5).sub.4, abbreviated TEOS), with greater efficiency and lower energy usage than prior abatement systems. More particularly, and in one preferred embodiment, the present disclosure is directed to a waste gas abatement system that utilizes a combination of non-combustible and combustible gases (or gas mixtures) for thermal combustion, which are directed through multiple permeable interior surfaces of a reaction chamber, efficiently combusting waste gas and preventing undesirable accumulation of solid particulate matter on the chamber surfaces.

The present disclosure provides a burner for a reduction reactor, the reduction reactor has a reaction space formed therein, wherein each burner has a fuel feeding hole and multiple oxygen feeding holes formed therein, wherein each burner has an elongate combustion space formed at one end of a head portion thereof, the combustion space fluid-communicating with the reaction space of the reactor, wherein the elongate combustion space has a length such that oxygen supplied from the oxygen feeding holes thereto is completely consumed via oxidation or combustion with fuels supplied from the fuel feeding hole thereto only in the elongate combustion space upon igniting the burner.

A burner, process and furnace are provided for regenerating a spent acid stream or other sulfur-containing stream by decomposing the spent sulfuric acid stream and/or other sulfur-containing stream to recover sulfur dioxide from the stream. The burner includes a burner body, and at least one spent acid feed passage positioned at least partially within the burner body or other sulfur-containing feed passage positioned at least partially within the burner body. At least one fuel feed passage may be positioned at least partially within the burner body. A related process and furnace are also provided.
