<p>PROBLEM TO BE SOLVED: To improve reliability and durability without increasing the size of a device under a condition that the combustion, reduced in the producing of NOx, is satisfied by a method wherein fuel, used for combustion in a combustion cylinder, is guided and fluid, necessary for the combustion, is guided also while a part of combustion gas, produced in the combustion cylinder, is guided to join with the guided fluid. SOLUTION: This combustion device comprises a combustion cylinder or an inner cylinder 32, whose inside is a combustion chamber 31, an outer cylinder 33, arranged around the outside of the inner cylinder 32, and a fuel guide mechanism 36, including a fuel supplying pipe 35 for supplying the fuel 34 used for combustion in the inner cylinder 32. Further, the combustion device comprises an air flow guide mechanism 37, guiding fluid, necessary for combustion or air, into the inner cylinder 32 through a space between the inner cylinder 32 and the outer cylinder 33, and combustion gas extracting mechanisms 38a, 38b, joining a part of high-temperature combustion gas, produced in the inner cylinder 32, with the flow of air, passing between the inner cylinder 32 and the outer cylinder 33. In this case, the downstream side of the combustion chamber 31 or the opening end side of the inner cylinder is communicated with a gas turbine through a gas guiding passage.</p> |
