Abstract: An oxy-fuel burner including a central burner element having a central conduit terminating in a central nozzle and an annular conduit terminating in an annular nozzle surrounding the central conduit, the central conduit flowing a first reactant and the annular conduit flowing a second reactant; a first staging conduit spaced apart from a side of the central burner element and terminating in a first staging nozzle; a second staging conduit spaced apart from an opposite side the central burner element and terminating in a second staging nozzle; a first mechanism to apportion a flow of the second reactant into a non-zero primary flow of the second reactant directed to the annular conduit and a non-zero secondary flow of the second reactant; and a second mechanism to selectively apportion the secondary flow of the second reactant between the staging conduits; wherein one reactant is fuel and the other reactant is oxygen.

Abstract: A system and method for synchronized oxy-fuel boosting of a regenerative glass melting furnace including first and second sets of regenerative air-fuel burners, a first double-staged oxy-fuel burner mounted in a first wall, and a second double-staged oxy-fuel burner mounted in a second wall, each oxy-fuel burner having a primary oxygen valve to apportion a flow of oxygen between primary oxygen and staged oxygen and a staging mode valve to apportion the flow of staged oxygen between an upper staging port and a lower staging port in the respective burner, and a controller programmed to control the primary oxygen valve and the staging mode valve of each of the first and second oxy-fuel burners to adjust flame characteristics of the first and second oxy-fuel burners depending on the state of operation of the furnace.
