The heating device has at least one inlet (30) for hot air not intended for combustion, at least one exit (20) for this same flow of air, and at least one channel (24-2, 24-3, 26,46, 48, 50) for transporting the air between the inlet and exit, so that the combustion air does not come into contact with the hot air. Heat generated during the combustion process is used to heat the air before it leaves the device. - Independent claims are also included for (a) a combustion chamber containing the device, and (b) an air heating method using the device. |
