Flame tube wall plate and method for machining cooling holes thereof

火焰筒壁板及其冷却孔的加工方法

Abstract

The invention relates to a flame tube wall plate, further relates to method for machining cooling holes in a flame tube wall of a combustion room of a combustion gas turbine and belongs to the technical field of aero-engines. The flame tube wall plate is provided with a plurality of cooling holes, wherein the cooling holes are evenly distributed in the flow line direction of high-temperature fuel gas flow and penetrate through the flame tube wall plate. In this way, efficient and even cooling gas films capable of being prevented from being torn through high-temperature fuel gas can be formed on the flame tube wall.
本发明涉及火焰筒壁板,属于航空发动机技术领域。该火焰筒壁板上具有沿高温燃气气流流线方向均匀分布且贯穿所述火焰筒壁板的多个冷却孔。通过这种设置,能够在火焰筒壁上形成高效均匀的冷却气膜并保证气膜不被高温燃气所撕裂。本发明还涉及一种燃气轮机燃烧室火焰筒壁的冷却孔的加工方法。
