ABSTRACT:
A heating process and its apparatus reduces air pressure within a chamber at a balanced level. The air retained within the chamber or the air suctioned through an outer air suction means is suctioned forcibly by rotation of rotary means disposed in the chamber and discharged outside the chamber through an inner air discharge means until air pressure within the chamber is reduced to a balanced level. Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the interior of the chamber is heated by air friction heat. Cooled outer air suctioned by the outer air suction means is heat-exchanged with heated air discharged by the inner air discharge means.
