PROBLEM TO BE SOLVED: To provide a melting furnace causing no blocking-up by molten slag in an opening of a blowing-in nozzle for blowing generated gas or combustion air or combustion gas in the melting furnace, and causing no hindrance to operation of the melting furnace. SOLUTION: This melting furnace burns the generated gas at a high temperature, and forms the molten slag by gathering and melting ash on a furnace wall surface by blowing and mixing the unburnt generated gas including the ash, and the combustion air or the combustion gas in the furnace, and is characterized by arranging eaves 24 composed of a refractory material projecting in the furnace by a prescribed dimension on a furnace wall inside surface 22a of a tip upper part of the blowing-in nozzle 21 for blowing the generated gas or the combustion air or the combustion gas in the furnace.
