Abstract
A method for protecting a tuyere assembly and a refractory lining of a furnace, and in particular a blast furnace, against damage caused by expansion of the refractory lining. This method includes providing a clearance between the tuyere assembly and a refractory lining portion below the tuyere assembly and monitoring this clearance by means of a displacement sensor.
