PURPOSE:To provide an excellent rotary furnace device, which brings technical effect, such as the reduction of oxidizing loss, as well as economical effects, such as the effective utilization of the area of installation and the saving of building expense as well as energy. CONSTITUTION:A plurality of sets of alternately-burning burners 3, in which two pieces of burners having heat accumulating bodies are assembled as one set and respective burners are burnt alternately, are arranged on the inside wall 2 of a rotary furnace. The alternately-burning burners 3 are provided on the inside wall 2 of the rotary furnace so as to be positioned at fore-and-aft or left-and-right of the upper part of the furnace body whereby the size of the whole of the furnace body can be reduced sufficiently. Especially, when the alternately-burning burners 3 are installed on the ceiling of the furnace body, a space for combustion can be enlarged whereby large-capacity burners can be installed and, further, the installation space will never be enlarged even when the large-capacity burners are installed. |
