Methods and devices for gas mixture combustion on a surface of a permeable matrix are provided which produce or result in surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the matrix surface and decreasing concentrations of pollutant components in the combustion products. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity and configured to preheat the combustible gas mixture as it travels through the matrix. The burner includes a plurality of thermal elements having a thermal conductivity higher than and disposed in thermal transfer communication with the matrix base material. The permeable matrix base material forms a combustion surface with at least a portion of the thermal elements exposed above the combustion surface. The gas mixture is combusted at or near exit pores and channels formed at the permeable matrix material combustion surface.

A plate body 11 of a combustion plate 10 is provided with no-burner port portion 13 where no burner ports 12 exist, and a burner port group 14 made up of a plurality of burner ports 12 is arranged in each region 15 of the plate body 11 surrounded by the no-burner port portion 13. A port diameter D of the burner ports 12 differs between the burner port groups 14, but the respective burner port groups 14 are made up of the burner ports 12 of the same port diameter D, and are arranged so that the greater the port diameter D of the burner ports 12 making up each burner port group 14, the greater the interval T between the burner ports 12 in the burner port group 14 becomes.

A combination burner apparatus includes: a housing including a peripheral wall defining an interior cavity; and side-by-side first and second burner assemblies disposed in the housing in fluid communication with the interior cavity, wherein the first burner assembly is of a first burner type, and the second burner assembly is of a second burner type different from the first burner type.

A tubular burner includes: a mixing tube having an inlet port into which a fuel gas and primary air flow; and a flame hole member having a plurality of flame holes and being fitted into a front end portion of the mixing tube. The flame holes of the flame hole member are made up of a central main flame hole and a plurality of subsidiary flame holes positioned around, and each being smaller than, the central main flame hole. In an annular region of the flame hole member defined between an outer periphery of the flame hole member and the central main flame hole, a plurality of non-flame-hole regions which are free from formation of the subsidiary flame holes are provided at a circumferential distance from one another. The plurality of the subsidiary flame holes are formed in each of flame hole regions defined between the non-flame-hole regions.

A method for a combustion system includes outputting fuel from an adjustable-position fuel nozzle onto a perforated flame holder, the fuel being directed for mixture with an oxidant en route to the perforated flame holder. A combustion reaction of the fuel and the oxidant is supported within the perforated flame holder. A position of the adjustable-position fuel nozzle may be changed relative to the flame holder. A first flow of fuel may be output when the adjustable position fuel nozzle is in an extended state, and a second flow of fuel may be output when the adjustable-position fuel nozzle is in a retracted state.

A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool, the radiant burner comprises: a sintered metal fibre sleeve through which combustion materials pass for combustion proximate to an inner combustion surface of the sintered metal fibre sleeve; and an insulating sleeve surrounding the sintered metal to fibre sleeve and through which the combustion materials pass. In this way, a radiant burner is provided which does not crack due to rapid cycling caused by frequent idle steps during which the burner is extinguished. Also, by providing an insulating sleeve, the temperature within the radiant burner and the temperature of an outer surface of the radiant burner remain comparable with existing ceramic burners. This enables the radiant burner to be substituted in place of existing ceramic burners as a line-replaceable unit which does not suffer from cracking during such frequent and short-duration periods of process tool inactivity.

A gas fired infrared burner includes a burner body with a primary inlet for gaseous fuel and air, the burner body defining a primary premixing chamber for receiving gaseous fuel and air from the primary inlet. An emitter arrangement is configured and positioned such that gaseous fuel and air flows through the emitter arrangement to be combusted at an external surface of the emitter arrangement. The burner body includes an auxiliary inlet for gaseous fuel and air, and the burner body defines an auxiliary premixing chamber for receiving gaseous fuel and air from the auxiliary inlet. The emitter arrangement includes an auxiliary emitter segment that receives gaseous fuel and air from the auxiliary premixing chamber such that combustible gases emitted from the auxiliary emitter segment can be ignited even when no combustible gases are being emitted from portions of the emitter arrangement that are fed from the primary premixing chamber.

A high intensity gas-fired infrared emitter including a frame having a plurality of side walls, an open bottom, and an open top, a flame arrestor mounted inside the frame and including a bottom, a top surface having a recess, and a plurality of apertures extending from the bottom to the recessed top surface, and a cellular surface panel formed of a plurality of cells and mounted inside the recess of the flame arrestor such that the plurality of apertures of the flame arrestor form pathways which extend into the cellular surface panel.

A burner gas supply apparatus for increasing flame turbulence, the apparatus comprising a conduit having a characteristic width, W, defined by an inner surface having a circumferential direction and an axial direction, the axial direction terminating in a nozzle defining a nozzle exit plane and having a characteristic dimension, d, where d<=W; and three bluff bodies each with a characteristic dimension, D.sub.bb-i, projecting a length, L.sub.i into the conduit from the inner surface, and an axial spacing X.sub.i between adjacent bluff bodies (between the downstream bluff body and the nozzle exit plane in the case of X.sub.1) wherein 0.5<=L.sub.i/W<=1 and wherein X.sub.i/D.sub.bb-i<=30.
