    • PROBLEM TO BE SOLVED: To optimize wet cleaning of an inflow area of an axial flow turbine having radial inflow.SOLUTION: A gas inflow housing of an exhaust gas turbine includes a tubular outer housing wall 10, and a hood-shaped inner housing wall 12 disposed inside of the outer housing wall. A flow passage defined by the outer housing wall, is changed from the tubular shape to the annular shape, the outer housing wall is curved so that the flow passage defined by the outer housing wall is deflected from a first direction different from an axial direction of a circular axis A of a circular outflow opening, to the axial direction, and further a cleaning nozzle 7 is guided through the outer housing wall, and intruded into the flow passage. The flow passage has an elliptical cross-section having a short symmetrical axis and a long symmetrical axis in an area of the cleaning nozzle, and the cleaning nozzle is extended along the short symmetrical axis of the elliptical cross-section of the passage.
    • 要解决的问题:优化具有径向流入的轴流涡轮机的流入区域的湿式清洗。解决方案:排气涡轮机的气体流入壳体包括管状外壳壁10和罩形内壳体壁12 设置在外壳体壁的内部。 由外壳壁限定的流动通道从管状改变为环形形状,外壳体壁弯曲,使得由外壳体壁限定的流动通道从与轴向方向不同的第一方向偏转 向轴向方向的圆形流出口的圆轴A和另外的清洁喷嘴7被引导穿过外部壳体壁并且侵入到流动通道中。 流路具有在清洁喷嘴的区域中具有短对称轴和长对称轴的椭圆形截面,并且清洁喷嘴沿着通道的椭圆形横截面的短对称轴延伸。
