Abstract

The present invention provides a flame propagation tube, a combustor, and a gas turbine including the same. In the combustor of the gas turbine, the flame propagation tube is disposed on an inner cylinder in which a combustion chamber for fuel ignition is formed and an outer cylinder provided so as to surround the inner cylinder, propagates the flame generated by the combustion chamber of the combustor to another adjacent combustor, includes a hollow insertion pipe configured to connect the inner cylinder and the outer cylinder, and a connection pipe disposed between a first combustor and a second combustor adjacent to each other and connected to the insertion pipes disposed on the first combustor and the second combustor so that the combustion chambers of the first combustor and the second combustor communicates via the connection pipe.

Description

technical field [0001] The present invention relates to a flame propagation pipe, a burner and a gas turbine including the same, more specifically, to a flame propagation pipe for transmitting flames between burners, a burner for generating high-temperature and high-pressure gas by burning fuel, and a gas turbine including the same gas turbine. Background technique [0002] Typically, a gas turbine consists of a compressor, a combustor, and a turbine. The compressor has a plurality of compressor stationary vanes and a plurality of compressor moving vanes alternately arranged in the compressor casing. In addition, the compressor draws in external air through a compressor inlet scroll strut. The air sucked in this way is compressed by the compressor vane and the compressor blade while passing through the inside of the compressor. [0003] The combustor receives the compressed air compressed by the above-mentioned compressor and mixes it with fuel. And the burner ignites th...
