A flow path forming plate, a flow path forming coarse member having the same, and a stator, a gas turbine, a method for manufacturing a flow path forming plate, and a method for converting a flow path forming plate

摘要

The flow path forming plate 60i includes a plate main body 61i, a main wall 65i, and a shelf 71. [ The plate main body 61i has a gas path surface 64p directed to the gas flow path side and an inner surface 64i directed to the side opposite to the gas path surface 64p. The peripheral wall 65i protrudes from the inner surface 64i to the half-flow path side along the periphery of the plate body 61i. The shelf 71 protrudes from the inner surface 64i to the half-flow path side along the inner wall surface of the peripheral wall 65i. The shelf 71 receives an impingement fingerboard 81 having a plurality of through holes 82. The shelf 71 is disposed only at a portion of the inner wall surface of the peripheral wall 65i.
