A gas burner device includes a burner; an injector configured to supply gas to the burner to generate a flame, the injector being on one side of the burner, the flame being generated around the burner as the gas supplied by the injector burns. The flame includes: a first flame portion farthest from an installation surface on which the gas burner device is installed, a second flame portion, and a third flame portion closest to the installation surface so that the second flame portion is between the first flame portion and the third flame portion and the second flame portion transitions the first flame portion into the third flame portion.

The present invention presents a scrubber burner composed of a preheating spray ring that is formed with a porous material with certain thickness, and that preheats and sprays the fuel gas in the preheating combustion space formed inside, a preheating guide ring equipped with multiple preheating guide holes that wrap the outer circumference of the aforementioned preheating spray ring, and that penetrates from the outer circumference to the inner circumference, and a preheating burner module equipped with a housing that forms a ring shaped gas channel that is separated from the outer circumference of the aforementioned preheating guide ring and through which the aforementioned fuel gas flows.

A recirculating micro-combustor device and a method of formation includes an array of reactors contacting each other. Each reactor includes a front wall; an end wall oppositely positioned to the front wall; a pair of edge walls connecting the front wall to the end wall; an inlet port positioned in the front wall; a pair of outlet ports positioned in the front wall; and a combustion chamber connected to the inlet port and positioned between the front wall and the end wall. The combustion chamber includes a pair of inner walls defining a first area to accommodate a chemical combustion therein, and a pair of second areas to accommodate an exhaust of a reaction of the chemical combustion. The pair of second areas connect to the pair of outlet ports. Adjacent edge walls of adjacent reactors directly contact each other to form the array of reactors.

A method for continuous firing of combustion chambers with at least three regenerative burners, wherein a first regenerative burner cyclically in the combustion mode conveys supply air and a second regenerative burner in the exhaust mode conveys exhaust air. To avoid escape of hazardous process gases from the combustion chamber into the environment and high carbon monoxide emissions, and to provide energy-efficient firing operation despite use of compact regenerators, the volume flow of the supply or exhaust air through the first or second regenerative burner is reduced continuously and in counter-cycle mode to the volume flow of supply or exhaust air through a third regenerative burner at constant combustion chamber pressure until the first or second regenerative burner is flow-free.

Methods and systems for oxidizing gas are provided. An example regenerative oxidizer is provided that includes a combustion chamber to heat gas present in the combustion chamber. The regenerative oxidizer also includes a first heat exchange media bed and a second heat exchange media bed. Each of the first heat exchange media bed and the second heat exchange media bed are in fluid communication with the combustion chamber. The regenerative oxidizer further includes two burners disposed within the combustion chamber to provide a total heat input to the gas present in the combustion chamber. At least one of the two burners is independently adjustable based on the airflow direction.

A method of melting a charge in a double-pass tilt rotary furnace having a door, including operating a first burner at a first firing rate, the first burner being mounted in a lower portion of the door and producing a first flame having a length; operating a second burner at a second firing rate, the second burner being mounted in an upper portion of the door and producing a second flame having a length, the second flame being distal from the charge relative to the first flame; in an initial phase when the solids in the charge impede the first flame, controlling the second firing rate to be greater than the first firing rate; and in an later phase after melting of the solids in the charge sufficiently that the first flame is not impeded, controlling the first firing rate to be greater than the second firing rate.
