A flameless thermal oxidizer includes a container in which a ceramic matrix is contained, and a diptube having a passageway extending therethrough, the diptube positioned in and in communication with the ceramic matrix and in which a plurality of gaseous streams are present for combustion at the ceramic matrix, the plurality of gaseous streams including a vent stream and an oxygen stream. A related method is also provided.

A flameless thermal oxidizer (FTO) includes at least one baffle constructed and arranged in a reaction chamber of the FTO to coact with a diptube of the FTO to radially expand a resulting “bubble” or reaction envelope from the diptube outward into a porous matrix of the FTO. A related method is also provided.

A method of fabricating a burner element for an abatement apparatus is disclosed. The method comprises: injection moulding a charge comprising metal particles and a flow compound into a mould defining the burner element to produce a moulded burner element; and sintering the moulded burner element. In this way, injection moulding is used to produce the burner element, which provides far more flexibility regarding the design and properties of the burner element and avoids the necessity of incorporating a perforated support into the burner element. This allows burner elements of more intricate design to be produced, as well as burner elements which are thinner than those produced using existing techniques, which increases the volume of a combustion chamber defined by that burner element for any external burner element size, which in turn increases the amount of effluent gas that can be treated for any burner size.

A power-to-X system for the utilization of off-gases, includes an electrolyzer for generating hydrogen H2 and oxygen O2, a unit, connected to the electrolyzer, for processing the hydrogen H2, for removing any remaining water H2O and oxygen O2 from the generated stream of hydrogen H2, a compressor, connected to the unit for processing the hydrogen H2, for compressing the hydrogen H2, and a chemical reactor, connected to the compressor, for producing a synthesis gas consisting of hydrogen H2 and carbon dioxide CO2 that can be added. An oxy-fuel combustion system to which non-condensable off-gases from the chemical reactor and oxygen O2 from the electrolyzer can be supplied, and carbon dioxide CO2 generated during the combustion of the off-gases in the oxy-fuel combustion system can be returned to the stream of hydrogen H2 downstream of the electrolyzer via a return line.

The present invention presents a scrubber burner composed of a preheating spray ring that is formed with a porous material with certain thickness, and that preheats and sprays the fuel gas in the preheating combustion space formed inside, a preheating guide ring equipped with multiple preheating guide holes that wrap the outer circumference of the aforementioned preheating spray ring, and that penetrates from the outer circumference to the inner circumference, and a preheating burner module equipped with a housing that forms a ring shaped gas channel that is separated from the outer circumference of the aforementioned preheating guide ring and through which the aforementioned fuel gas flows.

An inlet assembly for an abatement apparatus includes: an effluent stream conduit configured to convey an effluent stream along a major direction of flow within the effluent stream conduit; an inlet nozzle fluidly coupled with the effluent stream conduit and configured to convey the effluent stream received from the effluent stream conduit to an abatement chamber of the abatement apparatus; and a baffle interposed between the effluent stream conduit and the inlet nozzle, the baffle being shaped and configured to redirect flow of the effluent stream from the effluent stream conduit into the inlet nozzle by inhibiting effluent stream flow along the major direction of flow into the inlet nozzle. A line-of-sight flow from the effluent stream conduit into the inlet nozzle is prevented by the baffle and the effluent stream instead follows a non-line-of-sight or diversionary path from the effluent stream conduit into the inlet nozzle, which improves DRE.

A reactor apparatus, includes: a reactor chamber having an inlet through which treatment liquid containing by-products is introduced and having an interior space; a burner at a lower end portion of the reactor chamber to burn waste gas; a guide member above the burner and configured to allow the treatment liquid to flow outwardly of the burner; a water reservoir between the burner and the guide member, the water reservoir having a double pipe structure having an inner wall portion and an outer wall portion, and through which water supplied through a water inlet is configured to flow between the inner wall portion and the outer wall portion; and a cover member coupled to an upper end portion of the water reservoir and configured to cover a space between the inner wall portion and the outer wall portion, wherein an upper end of the outer wall portion is above an upper end of the inner wall portion, wherein a plurality of bumps are on a bottom surface of the cover member spaced apart from each other in a circumferential direction, the plurality of bumps configured to form a gap of several hundred pm between the bottom surface of the cover member and an upper surface of the inner wall portion of the water reservoir.

A method of cleaning a gas inlet nozzle of an abatement burner combustion chamber. The abatement burner intermittently receives gas for combustion from a feed process. The nozzle comprises a cleaning mechanism including a movable cleaning member for physically removing unwanted deposits from the nozzle. The cleaning member is movable from a retracted first position wherein the cleaning member is outside a path of a flame associated with the nozzle, to a second cleaning position wherein the cleaning member is in a path of the flame associated with the nozzle. The method comprises the steps of: a. identifying when the nozzle is out of use; b. moving the cleaning member from the first position to the second position while the nozzle is out of use; and c. returning the cleaning member to the first position before nozzle is in use.

Various implementations include an apparatus for thermal processing of medical waste. The apparatus includes a body, a conductive heater, and an air flow device. The body portion defines a chamber for receiving two or more containers of medical waste. The chamber is in fluid communication with a gas processing device for biological materials. The conductive heater is thermally coupled to the chamber to provide heat to the two or more containers. The air flow device is configured to direct discharge gases from the two or more containers to the gas processing device.

A method of optimising operating conditions in an abatement apparatus configured to treat an effluent stream from a processing tool and an abatement apparatus are disclosed. The method of optimising operating conditions in an abatement apparatus configured to treat an effluent stream from a processing tool comprises: determining a concentration of carbon monoxide produced by the abatement apparatus when treating the effluent stream; and adjusting an operating parameter of the abatement apparatus in response to the concentration of carbon monoxide. In this way, the performance of the abatement device can be controlled by simply adjusting the operating parameters of the abatement device in response to the amount of carbon monoxide being produced to create conditions within the abatement apparatus which improve the removal of compounds being treated within the abatement device, while reducing undesirable by-products and without requiring advanced knowledge of the content of the effluent stream.
