A method for decoking furnace tuyeres using a turbulent flow of gas enriched with impact-resistant particles. The non-abrasive particles which have no sharp edges are carried along in a concentration of approximately 0.1 to approximately 10 kilograms per kilogram of gas and the gas is introduced at the inlet end of the furnace tuyeres with a gas flow corresponding to a gas outlet velocity from approximately 1500 metres per minute to the speed of sound in the said gas, and preferably with a gas outlet velocity of approximately 4200 to 12000 metres per minute.
