Combustor of gas turbine with features for vibration reduction and increased cooling
First Claim
1. A combustor of a gas turbine having a plurality of combustor liners, a plurality of transition pieces connected to respective liners and adapted to rectify the flow of combustion gas coming from said liners, and a plurality of outer casings surrounding respective combinations of said liners and said transition pieces, comprising a guide plate having a radial portion disposed in each gap formed between each pair of adjacent transition pieces, said guide plate being adapted to rectify the air flowing through said gap, each guide plate having circumferential members that overlie the transition pieces and are attached to the radial portion of the guide plate, and said circumferential members form a gap between the adjacent circumferential members for exit of the cooling air.

Abstract
A combustor of a gas turbine having a plurality of liners defining combustion chambers, and transition pieces adapted to rectify the flow of the combustion gas discharged from the liners before the combustion gas is introduced to the turbine. A guide plate is disposed in the gap between each pair of adjacent transition pieces near the gas outlets of the latter so as to guide the flow of air to the radially outer surfaces of adjacent transition pieces, thereby to improve the cooling of these surfaces and, at the same time, to mechanically connect the adjacent transition pieces to suppress the vibration of the transition pieces.
