    • A gas turbine (1) includes a combustion chamber (2) followed by a stator airfoil row (4) defining a plurality of guide vanes and separated by the combustion chamber (2) by a first gap (5), and a rotor airfoil row (6) separated by the stator airfoil row (4) by a second gap (7). The stator airfoils (15) of the stator airfoil row (4) are connected to guide vane boxes (17) collecting a cooling fluid (A) and injecting it through nozzles (20) in the second gap (7) to make it to enter rotor airfoil inlets (23). The guide vane boxes (23) are provided with passages (30) connecting a zone (31) upstream of the guide vane boxes (17) to a zone (32) of the second gap (7) downstream of the guide vane boxes (32). Moreover, the mouths (3) of the passages (30) facing the rotor airfoil row (6) are closer to a hot gases path than the nozzles (20).
    • 燃气轮机(1)包括燃烧室(2),其后面是限定多个导向叶片的定子翼型排(4),并由燃烧室(2)分隔第一间隙(5),转子翼型排 (6)通过第二间隙(7)由定子翼型排(4)分开。 定子翼型排(4)的定子翼型件(15)连接到收集冷却流体(A)的引导叶片箱(17)并通过第二间隙(7)中的喷嘴(20)注入,使其进入 转子翼型进口(23)。 引导叶片箱(23)设置有将引导叶片箱(17)上游的区域(31)连接到导叶箱(32)下游的第二间隙(7)的区域(32)的通道(30) )。 此外,面向转子翼型排(6)的通道(30)的口(3)比喷嘴(20)更靠近热气路径。
