TUBULAR BURNER AND METHOD FOR OPERATING A TUBULAR BURNER

摘要

The invention is implemented in terms of the device on the one hand by a tubular burner for an industrial furnace, which has at least one annular first feed channel for a combustion gas and at least one radially further inwardly arranged second feed channel for fuel, wherein the two channels open out in a burner face. Also provided is at least one carrying-air feed opening, which is arranged in the burner face underneath the second feed channel for fuel and between the first and second feed channels and extends only in the lower half of the burner face. According to an alternative configuration, the tubular burner for an industrial furnace has at least one annular first feed channel for a combustion gas and at least one radially further inwardly arranged second feed channel for fuel, wherein the two channels open out in a burner face and the surface area of the opening of the first feed channel is larger in the lower half of the burner face than in the upper half of the burner face.
