<p>PURPOSE:To perform heating in a good environment by passing the atmospheric gas incorporating impurities for a heating oven through an adsorbent and removing the impurities. CONSTITUTION:Gaseous O2 fed from a pressure vessel 2 filled with gaseous O2 is introduced into the adsorption tower 5 or 7 via the ducts 3, 4 and water being impurities is removed by the adsorbents 8, 9 and pure gaseous O2 is fed to a heating oven 1 and utilized as the atmospheric gas for the heating oven. The adsorption towers 5, 7 are alternately utilized and when adsorption is performed in one tower, the other tower is subjected to regeneration. Waste gas discharged from the heating oven 1 is cooled by a heat exchanger 15 and thereafter sent to the adsorption towers 5, 7 to regenerate the adsorbents 8, 9 and discharged through a pipe 17.</p> |
