る。 In the atmospheric gas production device 27 configured as described above, the air-fuel mixture M is burned in the surface combustion burner 3 section, and at this time, since an oxidation catalyst (nickel) is present in the heat-resistant porous body section 4, it is mixed by the catalytic action of the oxidation catalyst. Hydrocarbons in gas M are effectively thermally decomposed even when the air ratio is less than 1.0, producing unburned hydrocarbons and exhaust gas G with extremely low oxygen concentration (approximately 3 ppm or less), and almost no soot is generated during combustion. It's not easy.
Furthermore, since the combustion speed can be increased, backfire can be prevented. The exhaust gas G is cooled and dehumidified by the cooler 10, flows into the adsorption tower 12, and becomes CO 2 and H 2 O.
After being adsorbed and removed, the atmospheric gas B flows through the conduit 21 into the heat exchanger 8, and after being heated to approximately 300°C by the flow of the heat exchanger 8, it passes through the atmospheric gas supply pipe 24 and enters the atmospheric furnace 23. Supplied. Thereby, it is possible to save fuel or electric power for heating the material to be heated in the atmospheric furnace 23. Further, a part of the high temperature atmospheric gas B (for example, 30% flow rate) flowing out from the outlet 22 of the heat exchanger 8 flows into the adsorption tower 13 as a regeneration gas through the regeneration gas supply pipe 25, and the adsorbent in the tower is Perform heating and dehumidification. This makes it possible to save energy for regenerating the adsorbent, which conventionally used electric heating or the like.

ることもできる。 The present invention is not limited to the embodiment described above. For example, in the embodiment described above, a part of the atmospheric gas B whose temperature has been increased by passing through the heat exchanger 8 is transferred to the adsorption device 11.
This is convenient because the heat source for regeneration can be procured within the atmospheric gas production device, but in some cases, the regeneration of the adsorption device 11 may be performed using another heat source to increase temperature. The entire amount of atmospheric gas B is supplied to the atmospheric furnace 23 and
The energy saving effect of 3 may be further improved. Further, in the above embodiment, the entire amount of the atmospheric gas B flowing out of the adsorption device 11 was introduced into the heat exchanger 8, but depending on the temperature of the atmospheric gas B, the calorific value in the combustion furnace 1, etc. The section may be bypassed directly to the atmospheric gas supply pipe 24 without passing through the heat exchanger 8, and an example of this bypass pipe is shown by a chain line 30 in FIG. Furthermore, the heat exchanger 8 may be of a type other than the double cylindrical type.
