<p>PROBLEM TO BE SOLVED: To provide a method and a device for heating the atmospheric gas in which the heat supply and the heating gas flow rate are not substantially fluctuated in a time-series manner, the heat efficiency is high, the resources (the atmospheric gas) can be recycled, and the running cost is low. SOLUTION: The thermal energy of the atmospheric gas to be discharged from a heating facility F is accumulated by using one 1C of two sets of rotary heat accumulation type heat exchangers, the air is preheated and fed to a burner B together with a fuel to generate hot gas, the heat energy of the hot gas generated by the burner B is heated by the other heat exchanger 1A, and the atmospheric gas is heated and fed to the heating facility F.</p> |
