An immersion-type burner heater includes a heater protection tube that is installed so as to penetrate a furnace wall or an upper lid of the molten-metal holding furnace with the tip end thereof being closed; an inner cylindrical member arranged inside the tube so as to define a combustion flow passage S between the tube and itself with the tip end side thereof being open and the inside thereof serving as an exhaust gas flow passage; and a gas burner part supplying fuel gas and air to the combustion flow passage. A helically extending projecting part is provided on at least one of the outer peripheral surface of the member and the inner peripheral surface of the tube at a position that is closer to its tip end side than to the part penetrating the furnace wall or the upper lid.

An integrated ITM micromixer burner shell and tube design for clean combustion in gas turbines includes an oxy-fuel micromixer burner for separating oxygen from air within the burner to perform oxy-combustion, resulting in an exhaust stream that consists of CO.sub.2 and H.sub.2O. The shell and tube combustion chamber is designed so that preheated air enters a headend having an array of ion transfer membrane (ITM) tubes that separate oxygen from the preheated air and anchor flamelets on the shell side. The combustion products of the oxy-fuel flamelets expand through a turbine for power generation, before H.sub.2O is separated from CO.sub.2 by condensation. A portion of the effluent CO.sub.2 is compressed back into the burner system, while the remainder is captured for sequestration/utilization.

An apparatus is provided for heating a road surface material to be repaired. The apparatus includes a frame and a heater connected to the frame so as to be positioned over a road surface, in use, for heating for heating a road surface material. An agitator is also connected to the frame for agitating a road surface material. The agitator is configured to agitate road surface material heated by the heater.

An infrared temperature equalizing device and a grill thereof having a first vertical plate, a first folded plate, a second vertical plate, and a second folded plate. The first folded plate is connected with the second folded plate to form a cover. The first vertical plate and the second vertical plate form a wall. The wall and the cover form a heat aggregation chamber for hot air aggregation and circulation, which has a closed top and a bottom opening with a longitudinal depth. The temperature equalizing device achieves heat aggregation, temperature rising, and temperature equalizing. Through infrared and convection heating, the grill can heat food evenly and roast the food quickly.

An apparatus and method for producing heat and electricity including a burner to produce radiant heat. A thermal-to-electric conversion device is integrated with the burner and proximate to the radiant heat. The conversion device provides a first side disposed toward the radiant heat and a second side disposed toward a cooling fluid flow path, such as combustion air for the burner or a media to be heated by the burner.

The present invention provides a deep fat fryer providing an oil vat for holding hot oil. The hot oil of the vat is heated by a heat exchanger system that includes a pair of heat tubes. Heat transfer along a length of the heat tubes is facilitated by a heat conductive baffle substantially filling the interior of the heat tubes in volume and length. Heated air and gas are forced through the dense and elongated baffle to facilitate heat transfer to the walls of the heat tubes.

The disclosure relates to a gas-heated infrared radiation emitter comprising at least one radiating screen, which is for example made of ceramic and/or metal, in the form of at least one plate comprising a lower main surface and an upper main surface that are distant from each other, and a plurality of through-prisms, which are preferably hollow, extending from the lower main surface to the upper main surface, each prism being defined by a polygonal base and by an axis. The prisms may be juxtaposed with one another so that their polygonal bases form a tiling of at least one portion of the lower and upper main surfaces of said plate.

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.

An inlet assembly for a burner includes an inlet nozzle defining an inlet aperture, a non-circular outlet aperture, and a nozzle bore extending along a longitudinal axis between the inlet aperture and the outlet aperture for conveying an effluent gas stream from the inlet aperture to the outlet aperture for delivery to the combustion chamber of the burner. The nozzle bore extends from the inlet aperture to the non-circular outlet aperture. A baffle couples the inlet portion with the outlet portion, and defines a baffle aperture positioned within the nozzle bore. The baffle aperture has a reduced cross-sectional area compared to that of the outlet portion adjacent the baffle. A secondary gas stream nozzle provides a secondary gas stream. The secondary gas stream nozzle being positioned to mix the secondary gas stream with the effluent gas stream within the nozzle bore.
