PURPOSE:To simplify constitution and improve ignition performance by installing a plug part for generating spark onto the outside of an injection port in a burner which is held onto a housing and is installed coaxially with the air guide cylinder part on a partitioning plate and jets out fuel. CONSTITUTION:In a combustor A1, a partitioning plate 5 having an air guide cylinder part 2 is held onto a housing 1, and an air chamber 3 and a combustion chamber 4 are separation-formed. Further, a plurality of heater tubes 6 are arranged onto the inner peripheral side of the combustion chamber 4. An injection port 71a is formed coaxially with the cylinder part 2 of the partitioning plate 5, and a burner 7a having a plug part 73a for generating spark is installed onto the outside of the injection port 71a. Fuel is jetted out from the injection port 71a through a fuel passage 74a and the hollow part 791 of the burner 7a, and ignited by the electric spark generated between a center electrode 81a and the opposed electrode 77a of an outer cylinder member 75a of the burner 7a. |
