<P>PROBLEM TO BE SOLVED: To provide a flue integrated burner having extremely high heat efficiency in comparison with a conventional one and suppressing a fuel consumption rate. <P>SOLUTION: This flue integrated burner comprises a combustion portion having a combustion chamber in which a burner body is internally mounted and which has a nozzle opened toward the inside of a furnace, a flue gas flow channel formed at the outer side of the combustion portion, and a flue portion comprising a flue communicating with the flue gas flow channel. A preheating flow channel for circulating supply air supplied from an air supply portion is formed at the outer periphery of the flue of the flue portion, and a combustion air flow channel for heating the supply air flowing in from the preheating flow channel and distributing the same into the combustion chamber is formed at the outer periphery of the combustion chamber of the combustion portion. <P>COPYRIGHT: (C)2009,JPO&INPIT |
