摘要

solid fuel / oxygen burner, method for combustion of solid fuel and oxygen in the burner, method for operating a regenerative furnace for fuel / air glass fusion using a burner, and regenerative furnace. It is a solid fuel / oxygen burner, including an upstream section, an intermediate section, and a downstream section, a solid fuel line extending between the intermediate and downstream sections to carry a solid fuel mixture. in a carrier gas, the solid fuel line having a larger cross-sectional area in the downstream section than in the middle section, and a tubular fuel separator positioned within the solid fuel line in the downstream section, the fuel separator being delimited by an inlet plane and an outlet plane, the fuel separator dividing the fuel line into an inner nozzle having a cross-sectional area and an outer annular nozzle having a cross-sectional area in which the relationship between the cross-sectional area of the outer nozzle and the cross-sectional area of the inner nozzle measured at the exit plane is greater than 1.
