A burner assembly for a gas furnace including a partition panel including an upstream side, a downstream side, at least two partition openings, and an intermediate transverse slot in communication with each of the at least two partition openings, wherein each partition opening is located adjacent to one another, and at least two burners configured to fire inward, the at least two burners operably coupled to the upstream side, wherein each burner is substantially aligned with each respective partition opening.

Tubular radiant element for industrial plants and the like, made of a metal material resistant to high temperatures, including at least one vertical tubular portion, optionally at least a curved tubular portion, provided with a surface (S), including at least one radiation and stiffening means arranged on at least a portion of the surface (S) of the tubular radiant element.

A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool and comprises: a combustion chamber having a porous sleeve through which combustion materials pass for combustion proximate to a combustion surface of the porous sleeve; a combustion characteristic monitor operable to determine combustion performance of the radiant burner by monitoring infra-red radiation emitted from the combustion surface; and a radiant burner controller operable to control operation of the radiant burner in dependence upon combustion performance determined by the combustion characteristic monitor. Accordingly, aspects recognize that if a burner is suffering from an excessive flow of air the burner pad or combustion surface will typically cool, which results in an increase in unwanted emissions in the exhaust produced by a radiant burner. The cooling also results in a reduction in infrared radiation determined by the combustion surface. The hydrogen flame of the radiant burner and the hydrocarbon flame of the burner pilot typically do not emit infrared radiation and thus a change in infra-red an radiation, for example, intensity, quantity or frequency, emitted by the combustion surface of the radiant burner can be used to diagnose an overflow of cold gas, typically air, in the combustion mixture fed into the system, for example, the combustion chamber. Once diagnosed appropriate ameliorative steps may be taken and, for example, the burner control logic may be operable to compensate by reducing air flow into the burner.

A cooking appliance is provided. The cooking appliance may include a burner pot having a plurality of mixing spaces and a gas valve device to adjust a flow rate of a gas to be supplied into at least one mixing space of the plurality of mixing spaces.

A burner and a method utilize a burner tile with an outer surface extending along the furnace wall and an inner surface defining a passageway. A fuel duct extends at least partially through the passageway and discharges fuel onto a burner head. The burner head forms a coanda-curved surface, wherein the fuel is directed onto the coanda-curved surface such that the fuel flows along the coanda-curved surface to the outer surface of the burner tile. There is an air channel defined by an outside edge of the coanda-curved surface and in fluid flow communication with the passageway such that air flows from the passageway through the channel to mix with the fuel so as to produce the combustible mixture.

A continuous heating furnace includes one or a plurality of closed type gas heaters each having a combustion chamber, a guide section that guides an exhaust gas, an exhaust hole that discharges the exhaust gas and a first radiation surface that extends in a direction perpendicular to a baking object conveyance direction wherein the first radiation surface is heated by combustion in the combustion chamber and heat from the guide section and transfers radiant heat to the baking object. The continuous heating furnace also has at least one exhaust heat transfer unit that is juxtaposed with a corresponding closed type gas heater in the conveyance direction, wherein the at least one exhaust heat transfer unit has a second radiation surface that communicates with the exhaust hole of a closed type gas heater and is heated by the exhaust gas, and a heat transfer acceleration unit that accelerates heat transfer from the exhaust gas to the second radiation surface in a direction perpendicular to the conveyance direction of the second radiation surface.
