Description of the Related Art Conventionally, for example, as a heating furnace for sintering ceramic electronic materials, it is easy to control the temperature inside the furnace, and the required electric energy can be procured only by drawing a conducting wire, which is very convenient in operation. Therefore, the electric furnace has been mainly used. However, although the electric furnace itself is highly convenient in this way, (1) fossil fuels and nuclear fuels are mainly used for power generation, and the thermal efficiency in the "fuel-power-heat" cycle is low, (2) In the electric furnace, an electric heater as a heating element is driven to generate heat, and here also the thermal efficiency in the "power-heat" cycle is low, and (3) when the electric furnace is actually used,
It is normal to continuously operate the electric heater as a heating element day and night, and such a state is maintained even when the product to be heated is not flown, and in that sense unnecessary heat energy is forced to drain. However, there are social demands that the use of electric furnaces should be avoided in order to save energy.

Has a structure in which the combustion exhaust gas comes into contact with the product to be heated (that is, a direct combustion heating structure) because it also serves as a product heating chamber, and thus the quality of the heat-treated product deteriorates. . However, there was an advantage that the heat generated by gas combustion was directly and efficiently transferred to the product.
