Patent ID: 8226405

Claim:
A full time regenerative type single radiant tube burner, comprising: a radiant tube type burner; a regenerating unit that regenerates exhaust gas heat generated from the burner and is used for preheating the intake combustion air; and an intake and exhaust switching device that passes the intake air and the exhaust gas to the regenerating unit and heat-exchanges them and simultaneously progresses the intake and exhaust processes of the burner to perform the full time combustion, wherein the intake and exhaust switching device includes: a first driver that supplies external injection air to a first regenerating chamber or discharges the exhaust gas heat-exchanged in the first regenerating chamber to the outside; a second driver that supplies the external injection air to a second regenerating chamber or discharges the exhaust gas heat-exchanged in the second regenerating chamber to the outside; a third driver that supplies the intake air preheated in the first regenerating chamber to the burner side or supplies the exhaust gas combusted in the burner to the first regenerating chamber; and a fourth driver that supplies the intake air preheated in the second regenerating chamber to the burner side or supplies the exhaust gas combusted in the burner to the second regenerating chamber.
