Abstract: A combustion method in which a fuel gas having a velocity less than 50 feet/second is mixed with a stream of motive gas having a velocity of a least 200 feet/second to form a stream with a velocity greater than 50 feet/second, and the mixed stream is combusted with oxidant. In particular the fuel with low velocity is produced when heated flue gas heats a regenerator through which a mixture of fuel and flue gas is then passed to undergo endothermic reactions that produce syngas which is fed into a furnace together with a motive gas stream. The motive gas stream can be fed inside the firing port, in the duct for the fuel or from points in a wall outside of the furing port at a specific distance. All embodiments lead to better control of the shape of the flame.

Abstract: A method of heating molten glass in a forehearth with a burner that extends into the forehearth above the molten glass from a side wall of the forehearth is described, wherein the fuel and oxidant outlets (29,30) open in a direction which is upstream or downstream relative to the direction (D) in which said molten glass is flowing. Relative dimensions and orientations of the oxidant / fuel conduits and outlets, design of the refractory material encasing the conduits, oxidant and fuel velocities at their respective outlets and the ratio of oxidant to fuel velocity are controlled to reduce formation of soot, reduce damage to conduits and refractory material and reduce condensation of material from the molten glass.
