A method is described of removing slag particles from the flame delivery end of the combustion chamber of a high velocity oxygen-fuel burner of an electric arc furnace and the like comprising the steps of supplying oxygen and fuel to the combustion chamber of a burner at a ratio and at volumes to form a a high velocity substantially stoichiometric flame directed to a work product in the furnace until slag present at the surface of the burner becomes hot, reducing the amount of fuel supplied to the combustion chamber of the burner to generate an oxygen-rich flame the major portion of which is contained in the combustion chamber to oxidize the previously heated hot slag, and then increasing the volume of fuel which directs a high velocity oxygen-rich flame from the burner in order to have the excess oxygen of the flame make intimate contact with the work product in the furnace.
