To cool quickly and/or uniformly combustion product in case of need by supporting the upper member that is provided with a combustion chamber rotatively on a lower member that is provided with a combustion product base through a bearing device.
A combustion furnace comprises a lower member 12 and an upper member 14 and these are engaged together through a bearing device 16. A bearing device 16 is comparatively large and supports the upper member 14 securely. The bearing member 16 is provided with a controller device and the controller device controls the necessary push up operation and rotating operation of the upper member 14 against the lower member 12 from the program inputted through a keyboard 30 securely. When the bearing device is operated by the operation of the controller device, the upper member 14 is pushed up and rotated, At this state, a handler can approach the combustion product easily. The air flow through the high temperature combustion furnace is increased, the combustion product is cooled rapidly and perfectly.
