Abstract: A tuyere cooling system which includes a coolant circuit for a body section and nose section. A valve is operable to connect the coolant circuits in series or to disconnect flows to the nose section of the tuyere so that if the nose of the tuyere tears during operation, the flow of coolant to the nose section of the tuyere may be cut off without affecting the overall operation of the blast furnace.
