<P>PROBLEM TO BE SOLVED: To provide a burner for performing stable high temperature air combustion using high temperature low oxygen air discharged from a solid oxide fuel cell device as an oxidizer and its operation method. <P>SOLUTION: This burner includes a gas gun 2 disposed in the central part and an air feed pipe group 3 disposed in the outer peripheral part of the gas gun, wherein the gas gun 2 includes a fuel feed pipe 21 for feeding gas fuel and a pilot air feed pipe 22 disposed coaxially with the outer peripheral part thereof to feed fresh pilot air, and the air feed pipe group 3 includes a plurality of air feed pipes 31 for feeding fresh air and a plurality of combustion exhaust gas feed pipes 32 for feeding high temperature low oxygen air. In this burner, these two kinds of feed pipes are alternately disposed on the circumference, and an exhaust nozzle of the gas gun is located at the inner side of the burner more than the exhaust nozzle of the air feed pipe group. <P>COPYRIGHT: (C)2009,JPO&INPIT |
