排气室维护方法
摘要：
一种燃气涡轮机的排气构件及排气室维护方法，其中，设有：内侧扩散器(52)，其形成为圆筒形状并沿圆周方向被分割为多个；第1密封外壳(73)，其形成为圆筒形状并沿圆周方向一体构成，前端部连结至内侧扩散器(52)的后端部；第2密封外壳(74)，其形成为圆筒形状并沿圆周方向一体构成，前端部连结至第1密封外壳(73)的后端部；支撑连结部(75)，其支撑第1密封外壳(73)的后端部和第2密封外壳(74)的前端部，使其可沿轴向移动。从而易于拆下和安装壳体，并可实现维护性的提高。
摘要（英）：

In a gas turbine exhaust member and an exhaust chamber maintenance method, the gas turbine exhaust member is provided with: an inside diffuser that forms a tubular shape and is divided into multiple parts in the circumferential direction; a first seal housing that forms a tubular shape and is integrally formed in the circumferential direction, the front end of which being coupled to the rear end of the inside diffuser; a second seal housing that forms a tubular shape and is integrally formed in the circumferential direction, the front end of which being coupled to the rear end of the first seal housing; and a supporting coupling part that supports the rear end of the first seal housing and the front end of the second seal housing so as to allow the rear end and the front end to move in the axial direction.
