    摘要: A process and furnace for melting glass is set forth wherein the majority of the combustion energy over the melting zone of the furnace is provided by oxy-fuel combustion while a majority of the combustion energy over the fining zone of the furnace is provided by air-fuel combustion. In many cases, it will be preferable to provide greater than 70% and up to and including 100% of the combustion energy over the melting zone by oxy-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the fining zone by air-fuel combustion. By proper tailoring of the combustion space atmosphere through oxy-fuel and air-fuel firing, the present invention can result in an improvement in glass productivity and quality. The present invention can be applied in the construction of a new furnace or can be applied to existing air-fuel furnaces.

    摘要: A burner includes separate fuel and oxidant conduits. The fuel conduit has inlet, transitional, and outlet sections, and the oxidant conduit has inlet and outlet sections. The burner has a longitudinal axis and including a burner tip having a first elongated edge adjacent a flow of the fuel, and a second elongated edge adjacent a flow of an oxidant and forming a primary tip angle (α) of less than about 15° from a line parallel to the longitudinal axis and intersecting an upstream surface parallel to the longitudinal axis. The first elongated edge and the second elongated edge form a secondary tip angle (β) greater than the primary tip angle (α) and less than about 90° from a line tangent to and extending from the first elongated edge in the direction of the flow of the fuel.
