組立９分解が容易で、信頼性の高い火炎伝播管カバー管
構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a flame propagation tube system for a gas turbine combustor, particularly in the narrow space between the combustor casings.
This invention relates to a highly reliable flame propagation tube cover tube structure that is easy to assemble and disassemble.
多缶式燃焼器をもつガスタービンでは、ある燃焼器に点
火、燃焼させ、その火炎を他の燃焼器に火炎伝播管を通
して伝え、全燃焼器を着火させる方法をとる。In gas turbines with multi-can combustors, one combustor is ignited and combusted, and the flame is transmitted to the other combustors through flame propagation tubes to ignite all the combustors.
火炎伝播管構造は、特許番号第１１６１６５５号内の従
来例及び実施例に記載のように、燃焼器ライナ間に連結
する一体、または、分割体の構造がある。Flame propagation tube structures include integral or segmented structures that connect between combustor liners, as described in the prior art and examples in Patent No. 1,161,655.
この火炎伝播管の外側に設けられるカバー管は、各外筒

炎伝播管カバー管構造では、フランジ面では大きなずれ
を生じることになり、組立が困難となる。In order to improve the efficiency of gas turbines, when creating a more compact combustor structure, the combustor is often placed at a certain angle to the turbine axis. In the case of an angled structure, it is also necessary to process the casing to which the combustor is attached and the flame propagation tube cover pipe attachment surface of the combustor outer cylinder into an angled surface. This machining accuracy is significantly lower than that of a structure arranged parallel to the axis, and with the flame propagation tube cover tube structure in this patent, a large deviation occurs at the flange surface, resulting in assembly becomes difficult.

付けらおる構造において、燃焼器を取付けるケーシング
面、火炎伝播管カバー管を取付ける燃焼器外筒フランジ
面の機械加工精度の大幅な低下については考慮されてお
らず、組立困難な状況となる。In a structure in which the combustor is installed at an angle to the axis, the above conventional technology significantly reduces the machining accuracy of the casing surface to which the combustor is attached and the flange surface of the combustor outer cylinder to which the flame propagation tube cover tube is attached. This does not take into account the drop in temperature, making assembly difficult.

燃焼器外筒間の火炎伝播管カバー管の固定をリジットに
せず９片端は、パツキンを介して固定し。Instead of fixing the flame propagation tube cover tube between the combustor outer cylinders with a rigid structure, one end of the flame propagation tube is fixed with a gasket.

ランジを設けることによりカバーする。In addition, the length of the flame propagation tube cover tube is shorter than the distance between the cover tube mounting flange surfaces of the combustor outer tube so that the flame propagation tube can be easily assembled and disassembled in the limited narrow space between the combustor outer tube. This shortened length □ is covered by providing an intermediate flange on the side where the packing is fixed.
この構造は、火炎伝播管まわりの構造をシンプル化でき
、信頼性の向上にも結びつく。This structure simplifies the structure around the flame propagation tube and improves reliability.
