PURPOSE: To facilitate exchange of a heat storage body by a method wherein a fuel nozzle is so arranged to be opened in a furnace body located away from a heat storage chamber and an inner-furnace radiation tube is installed in the furnace body to charge a material to be heated on the center axis thereof. CONSTITUTION: Heat storage chambers 3A and 3B which are opened in a furnace body 1 while making a pair are arranged in the furnace body 1. Fuel nozzles 4 to be set corresponding to the respective heat storage chamber 3A and 3B are so arranged to be opened in the furnace body 1 located away from the heat storage chambers 3A and 3B. An inner-furnace radiation pipe 6 is installed in the furnace body 1 to charge a material 5 to be heated on the center axis thereof. When the furnace body 1 is used as a melting furnace, it is inclined slightly so that molten metal 7 flows out naturally and can be introduced into a holding chamber 13 at a pouring gate. This facilitates the exchanging of a heat storage body 11 and can minimize the oxidation of the material 5 to be heated thereby enabling significant reduction in a scale loss. |
