A radiant burner for treating an effluent gas stream from a manufacturing processing tool includes: a porous sleeve at least partially defining a treatment chamber and through which treatment materials pass for introduction into the treatment chamber; and an electrical energy device coupled with the porous sleeve and operable to provide electrical energy to heat the porous sleeve which heats the treatment materials as they pass through the porous sleeve into the treatment chamber. In this way, electrical energy, rather than combustion, is used to raise the temperature within the treatment chamber in order to treat the effluent gas stream.

A porous-medium premixing combustor is provided, which includes: an air-fuel gas mixer, a combustor body, a thermocouple, an ignition electrode, and a detecting electrode. The combustor body includes a casing connected to the air-fuel gas mixer; an outer and an inner burner-block, wherein the outer burner-block and the casing are connected, forming a square chamber, and the inner burner-block is provided inside the square chamber, with a via hole communicating with a pipe; and a mixed gas distributing plate, an ordered porous plate, a small-pore foamed ceramic plate, and a big-pore foamed-ceramic plate sequentially provided along an axis direction of the via hole of the inner burner-block. The thermocouple is provided at the casing and extends into the square chamber. The ignition electrode is provided close to an end of the big-pore foamed-ceramic plate. The detecting electrode is provided close to an exit end of the big-pore foamed-ceramic plate.

A thimble shaped burner is made of a porous foam metal material and is adapted to be mounted on the interior of a plenum chamber receiving a fuel/air mixture under pressure. The fuel/air mixture infuses into the interior of the thimble shaped burner body and exits from it through a burner port in a support structure where the fuel/air mixture that has been infused through the burner body is ignited. The burners are typically used in multiples and are mounted by means conventional fasteners passing through reinforced mounting flanges on the interior of an air fuel plenum chamber. Flame lift off is reduced or eliminated by particular configurations and dimensions of annular metal washers that are used in association with the burner bodies for mounting purposes.

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.

The present invention is directed to a heating adaptor device and method to use that heating adaptor device to replace a 1960-era infrared heater with a modern infrared heater while retaining a 1960-era pipe system. Without the heating adaptor device, (a) the 1960-era pipe system has to be replaced to avoid the known deleterious effects that would occur.

Methods of burning combustible gas mixtures on a surface of a permeable matrix providing surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the surface of the permeable matrix and decreasing concentrations of pollutant components in the combustion products are provided. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity. The gas mixture is preheated as it travels through the permeable matrix material. The gas mixture is then combusted at or near exit pores and channels formed at a combustion surface of the permeable matrix material, the combustion surface at least in part coated with a coating material having a thermal conductivity less than the permeable matrix material thermal conductivity and a high optical transmittance in the infrared spectrum.
