The inside of the furnace, which is illustrated below in center, is heated by the burner. This heating method has been innovated. As exhaust & inhalation (of combustion air or/and exhaust gas) is passing through pipe left to right and left to right alternately, the alumina ball(illustrated middle left and middle right) is done heat exchange (heated & cooled). As a result, this system contributes to fuel efficiency & CO2 reduction.
