Because the circulating air is directly heated by the burner 9, for example, when heating a car body to be painted, the solvent that evaporates from the burner flame and the high temperature (500 to 1500 degrees Celsius) in the vicinity. When exposed to water, it thermally decomposes, producing yellow substances that adhere to the car body and cause yellowing of the paint film, and hardening accelerators that accelerate the hardening of the paint film. In particular, it causes intense white yellowing and poor adhesion between the intermediate coat and top coat, so-called interlayer peeling. Conventionally, yellow substances and hardening accelerators were discharged from the drying oven, and ventilation was performed inside the drying oven in order to lower their concentration. Because of the necessity, there was a problem that a large amount of heat loss was involved.

The circulating air passes through the outside of the cylindrical body and is heated, so that the circulating air no longer comes into direct contact with the flame and high-temperature air of the heating device, and the solvent content in the circulating air is reduced. It does not thermally decompose into yellow substances or hardening accelerators. Further, according to the second invention, since the inside of the cylinder becomes negative pressure, the circulating air flows into the cylinder and is directly heated by the flame, but when passing through the cylinder, the solvent contained in the circulating air is removed. It is decomposed into harmless water and carbon dioxide by the catalyst supported on the cylinder, and similarly no yellow matter or hardening accelerators are generated.

る。 Here, the heating conditions in the first example will be specifically explained. The burner 9 uses 30,000 to 300,000 kcal to maintain the circulating air in the furnace body 2 within a predetermined temperature range.
The combustion heat is transferred from the inner metal cylinder 18 to the outer metal cylinder 18 with a gap. At this time, in order to make the distribution of temperature transmitted to the inner and outer metal cylinders 18 as constant as possible, outside air at a rate of 0.5 to 5 m 3 /min is supplied to the flame 1 from the nozzle 19.
7 and added to the heated air inside the metal cylinder 18. As a result, the temperature distributed in the inner metal cylinder 18 becomes 300 to 600°C,
Furthermore, the temperature distributed in the outer metal cylindrical body 18 with a gap is 300 to 400°C, and the "variation" in the temperature distribution becomes small. Therefore, as described above, the circulating air can be brought into contact with the metal cylinder 18 and heated to a desired temperature. The contact area of burner combustion air between the inner and outer porous metal cylinders 18 is approximately 1700 m 2 /m 3 .
