    摘要： A treatment apparatus for treating an effluent gas includes a combustion chamber; a burner; an inlet for receiving secondary combustion air; an exhaust gas outlet for outputting exhaust gases from the combustion chamber; and a heat exchanger. The heat exchanger is configured to exchange heat between a first fluid and a second fluid flowing through respective first and second fluid flow paths. The first fluid flow path is connected to the inlet and the second fluid flow path is connected to the outlet such that the exhaust gases received at the outlet flow into the second fluid flow path. The heat exchanger comprises a fluid flow communication path for providing a path for flow of a portion of the exhaust gases from the second fluid into the first fluid; and at least one inlet aperture for inputting the first fluid to the combustion chamber.

    摘要： The abatement apparatus includes a porous element at least partially defining a treatment chamber and through which treatment materials pass for introduction into the treatment chamber for treatment of an effluent gas stream; and an infra-red heating device operable to emit infra-red energy to heat the porous element which heats the treatment materials as they pass through the porous element into the treatment chamber. In this way, infra-red energy, rather than combustion, can be used to raise the temperature within the treatment chamber in order to treat the effluent gas stream. This allows the apparatus to be used in environments where no fuel gas exists or where the provision of fuel gas is considered undesirable. Also, heating the treatment materials as they pass through the porous sleeve, rather than simply using radiant heat to heat the treatment chamber enables significantly more energy to be imparted into the treatment materials.

    摘要： Aspects relate to monitorable plasma torch device components and in particular to monitoring and predictive maintenance of one or more such monitorable plasma torch device components. One aspect provides a monitorable plasma torch device component, the component comprising: a component body and a sacrificial component located in an erosion zone of the component body. The sacrificial component comprises material which differs from the plasma torch device component body and which, on exposure to a plasma torch in a plasma torch device, generates electromagnetic radiation distinct from that of the plasma torch device component body. The distinct electromagnetic radiation generated is indicative of erosion of the monitorable plasma torch device component in the erosion zone. Such a monitorable plasma torch device component can facilitate effective component monitoring which allows for ameliorative action to be taken in the event that degradation of the device component is detected.

    摘要： A method for fabricating a component of an abatement apparatus is disclosed. The method comprises: meshing a 3D model representation of a component defining a reaction chamber of an abatement apparatus based on specified component characteristics to define an optimised finite element representation of the component; and fabricating the optimised finite element representation. In this way, a 3D model of a component of an abatement apparatus can be generated from which its performance can be modelled. Particular characteristics of the component may be defined which affect the operation of the abatement apparatus. Those characteristics may then be used to generate the optimized finite element representation of the component which has those characteristics using meshing (it will be appreciated that meshing is the operation of representing a geometric object as a set of finite elements). The optimized finite element representation may then fabricated, reliably producing a component having the required characteristics.
