Abstract
1. Liquid-cooled, especially water-cooled tuyere for coke-controlled shaft furnaces, wherein, between inner shell and outer shell of the tuyere, a system of helically orientated ducts is disposed, of which one duct supplies the coolant to the tuyere head and one duct returns the coolant from the tuyere head, and an intermediate shell disposed between inner and outer shells separates the two ducts from each other and wherein the inner shell and outer shell are welded to each other directly or indirectly via a headpiece, characterized in that, for a tuyere internal diameter of - 80 to 120 mm, the difference from the outer diameter is less than 60 mm, - 120 to 180 mm, the difference from the outer diameter is less than 70 mm, - 180 to 250 mm, the difference from the outer diameter is less than 80 mm, - more than 250 mm, the difference from the outer diameter is less than 90 mm, and that between inner, cute and intermediate shells (15, 16, 31, 32), wires (18, 19) are disposed as a lateral boundary for the ducts.
