    摘要： A swirler-ferrule assembly includes a radial swirler, a ferrule, a fuel nozzle, and a surface feature. The radial swirler includes a primary swirler vane having a primary air passage and a secondary swirler vane having a secondary air passage. The ferrule may be connected to the radial swirler. The surface feature may be located on the primary swirler vane and/or the ferrule. The surface feature may be configured to direct an air flow through the primary air passage away from a recirculation zone located upstream of the primary swirler vane. The surface feature has a trailing end and a distal end, and the fuel nozzle is axially aligned with the trailing end of the surface feature or is located axially downstream of the trailing end of the surface feature. The surface feature may have a plurality of grooves.

    摘要： A device for igniting oxygen thermal lances or melting lances may include: a cartridge configured to couple to an operating end of a thermal or melting lance, configured to be supplied with oxygen to ignite the lance, and containing high calorific value material; and an induction heater assembly configured to heat the cartridge, such that the high calorific value material is burnt before supplying the oxygen into the cartridge to ignite the lance. The cartridge may include: a first end configured to couple to an operating end of a lance; and a second end having one or more axial holes for passing oxygen into the cartridge. An assembly for igniting oxygen thermal lances or melting lances may include: the device; the lance coupled to an end of the cartridge; a robotic arm configured to handle the lance; and a supply of oxygen in fluid communication with the lance and cartridge.

    摘要： A hydrogen flame ionization detector includes a base having an opening and a passage, a nozzle having a tubular section and an ejection section, and a collector. The tubular section is housed within the passage of the base with a gap between an outer peripheral surface of the tubular section and an inner peripheral surface of the passage. The outer peripheral surface of the ejection section is in direct surface contact with the base at an upper end portion of the passage. The surface contact forms a sealing portion that prevents a gas from leaking upward along an outer side of the ejection section, and the base is configured to function as a heat sink for absorbing heat of the nozzle.

    摘要： A pilot unit for an abatement apparatus and a method are disclosed. The pilot unit is for an abatement apparatus configured to abate an effluent stream from a semiconductor processing tool. the pilot unit comprises: a housing retaining a foraminous pilot surface. the housing and foraminous pilot surface defining a plenum which is configured to convey fuel and oxidant from a corresponding housing inlet and through that foraminous pilot surface: and an ignitor configured to ignite the fuel and oxidant when exiting the foraminous pilot surface. In this way. rather than having an ignition flame combusting from a nozzle. an ignition flame is provided across the foraminous pilot surface which provides for a more reliable ignition source for the abatement apparatus.

    摘要： A supercritical hydrothermal combustion device comprises a main enclosure and a top cap. A partition is mounted in the main enclosure and divides the interior of the main enclosure into a main combustion space and a mixing space. The top cap is provided with a primary fuel inlet, an oxidant inlet and a secondary fuel inlet. A high-temperature ignition bar sleeve, having a high-temperature ignition bar arranged therein, is disposed in the top cap. A combustion sleeve, having a stable combustion space formed therein, is mounted at a bottom of the top cap, and has a top communicated with the high-temperature ignition bar sleeve and the oxidant inlet, as well as a bottom communicated with the main combustion space. The secondary fuel inlet and a secondary oxidant inlet are communicated with the main combustion space. Supercritical hydrothermal combustion is realized to generate a hybrid thermal fluid or treat organic wastes.

    摘要： The present disclosure discloses an energy-efficient upside-entrainment burning system, which includes: a gas distributor component, an ejection pipe component, an outer-ring burner cap, an inner-ring burner cap, a plurality of gas nozzles. The ejection pipe component is arranged below gas distributor component, is provided with two ejection channels in a centrosymmetric structure corresponding to the outer-ring gas mixing chamber, also provided with two ejection channels in a centrosymmetric structure corresponding to inner-ring gas mixing chamber. Each ejection channel is arranged in a Venturi pipe structure. In a gas flowing direction, an ejection pipe inlet, a contraction section, a throat section, an expansion section, an ejection pipe outlet are arranged in sequence. An ejection capability is taken as a target parameter, each ejection capability parameter is of adjustment simulation to obtain optimum design of each structural detail of burner to form the energy-efficient upside-entrainment burning system with an optimum ejection capability.
