PROBLEM TO BE SOLVED: To provide a technology capable of efficiently reducing discharge of air polluting material, while excellently absorbing axial extension of a combustion cylinder 30 due to thermal expansion with simple structure, in regard to a combustion device 100 for a gas turbine engine structured by arranging a combustor 10 for burning fuel G supplied through a fuel supply pipe 50 provided inside a combustor casing 1 by using air A inside the combustor casing 1 in a cylindrical combustor case 1 for driving a turbine 5 by supplying the compressed air A from an air opening 2 formed in one end thereof and by injecting combustion gas CG from an injection opening 3 formed in the other end thereof, and by forming the combustor 10 by arranging a pre-mixer 20 for forming pre-fuel-air-mixture by mixing the fuel G and the air A and the combustion cylinder 30 for burning the pre-air-fuel-mixture M formed by the pre-mixer 20 by receiving it in order from an upstream side. SOLUTION: In this combustion device for a gas turbine engine, at least one part of a fuel supply pipe 50 is structured of a flexible tube 51. COPYRIGHT: (C)2006,JPO&NCIPI
