Abstract

A tuyere for injecting fuel e.g. hydrocarbon and combustive e.g. oxygen into shaft furnaces has a double walled cooling fluid circulation jacket. The tuyere has >=1 fluid fuel pipe and >=1 combustive pipe which laterally penetrate the jacket and emerge in proximity to each other beyond the jacket via its posterior surface or interior (furnace side) wall.
