US 2019/0101013 A1 · CONJUNCTION ASSEMBLY AND GAS TURBINE COMPRISING THE SAME

Abstract

A conjunction assembly provides a seal, in a connected state, between a conjunction ring constituting an outlet of a combustor and a turbine inlet cylinder constituting an inlet of the turbine. The conjunction assembly includes a connecting member that protrudes from the conjunction ring; a connecting groove for receiving the connecting member, the connecting groove formed in the turbine inlet cylinder; and a connection sealing member disposed between the connecting member and an inner surface of the turbine inlet cylinder to provide a seal between the connecting member and the inner surface of the turbine inlet cylinder. The connecting member is a ring-like structure formed on a rear-side surface of the conjunction ring, the rear-side surface facing the turbine inlet cylinder, and the connecting groove is formed in a front-side surface of the turbine inlet cylinder in correspondence to the connecting member, the front-side surface facing the conjunction ring.

Dependent claims

A conjunction assembly that seals, in a connected state, a conjunction between a conjunction ring that constitutes an outlet of a combustor and a turbine inlet cylinder that constitutes an inlet of a turbine, the conjunction assembly comprising:

a connecting member that protrudes from the conjunction ring;
a connecting groove for receiving the connecting member, the connecting groove formed in the turbine inlet cylinder;
and
a connection sealing member disposed between the connecting member and an inner surface of the turbine inlet cylinder to provide a seal between the connecting member and the inner surface of the turbine inlet cylinder.

1 more element

A gas turbine comprising:

a compressor that sucks and compresses air;
a combustor that includes a liner in which fuel is burned with the compressed air to produce combustion gas, a transition piece through which the combustion gas passes, and a conjunction ring coupled to an end of the transition piece;
a turbine that includes a turbine inlet cylinder that is disposed to be connected to an end of the conjunction ring and that passes the combustion gas to generate electricity;
and
a conjunction assembly that includes
a connecting member that protrudes from the conjunction ring;
a connecting groove for receiving the connecting member, the connecting groove formed in the turbine inlet cylinder;
and
a connection sealing member disposed between the connecting member and an inner surface of the turbine inlet cylinder to provide a seal between the connecting member and the inner surface of the turbine inlet cylinder.
