Flame tube wall plate and method for machining cooling holes thereof



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.
