Abstract:
(EN) A flow path forming plate (60i) is provided with a plate body (61i), a peripheral wall (65i), and a shelf (71). The plate body (61i) includes: a gas-path surface (64p) facing a gas flow path side; and an inner surface (64i) facing a side opposite to the side which the gas-path surface (64p) faces. The peripheral wall (65i) protrudes from the inner surface (64i) toward a side opposite to the flow path, along the peripheral edge of the plate body (61i). The shelf (71) protrudes from the inner surface (64i) toward the side opposite to the flow path, along an inner wall surface of the peripheral wall (65i). The shelf (71) receives an impinging plate (81) having a plurality of through-holes (82) therein. The shelf (71) is disposed only on a part of the inner wall surface of the peripheral wall (65i).
(FR) L'invention concerne une plaque formant trajet d'écoulement (60i) qui est dotée d'un corps de plaque(61i), d'une paroi périphérique (65i) et d'une étagère (71). Le corps de plaque (61i) comprend : une surface de trajet de gaz (64p) orientée vers un côté de trajet d'écoulement de gaz; et une surface interne (64i) orientée vers un côté opposé au côté vers lequel est tournée la surface de trajet de gaz (64p). La paroi périphérique (65i) fait saillie depuis la surface interne (64i) vers un côté opposé au trajet d'écoulement, le long du bord périphérique du corps de plaque (61i). L'étagère (71) fait saillie depuis la surface interne (64i) vers le côté opposé au trajet d'écoulement le long d'une surface de paroi interne de la paroi périphérique (65i). L'étagère (71) reçoit une plaque incidente (81) possédant plusieurs orifices traversants (82). L'étagère (71) est disposée uniquement sur une partie de la surface de paroi interne de la paroi périphérique (65i).
(JA) 流路形成板(60i)は、板本体(61i)と、周壁(65i)と、棚(71)とを備える。板本体(61i)は、ガス流路の側を向くガスパス面(64p)と、ガスパス面(64p)と相反する側を向く内面(64i)とを有する。周壁(65i)は、板本体(61i)の周縁に沿って、内面(64i)から反流路側に突出している。棚(71)は、周壁(65i)の内壁面に沿って内面(64i)から反流路側に突出している。棚(71)は、複数の貫通孔(82)を有するインピンジ板(81)を受ける。棚(71)は、周壁(65i)の内壁面の一部分にのみ配置されている。
