AI Technical Summary

Problems solved by technology

At a minimum, this flameback degrades the performance of the equipment, and if the flameback causes damage to the burner, the cost of repair or replacement is considerable, especially if the equipment has to be shut down
Where there are many burners in a furnace, often hundreds of burners, the risk of flashback in at least one of these burners can be considerable

Abstract

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-curvedsurface 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.

Description

technical field [0001] The present disclosure relates to the field of industrial burners, and in particular to radiant wall burners operating to heat the surrounding portion of the wall of a furnace or the like. Background technique [0002] Radiant wall burners are used in industrial applications to heat the surrounding part of the wall of a furnace or the like. For example, radiant wall burners are used in the petrochemical industry for processes such as hydrogen reforming, ammonia reforming, ethylene cracking, and ethylene dichloride (EDC) cracking. Most burners currently used for these applications consist of premix burners, which feature fuel gas and combustion air mixed together in a venturi before entering the furnace and burning. Additionally, combustors are commonly used with various fuel gases such as natural gas, liquefied petroleum gas (LPG), refinery gas, and mixtures thereof. Fuel gas may contain varying amounts of hydrogen, depending on the fuel gas mixture ...
