ABSTRACT:
A solid wheel turbine including a series of spaced overlapping buckets suitable for use in high quality and wet steam applications is disclosed. Complex flow passageways for buckets in a turbine wheel are utilized to achieve both high erosion resistance and improved performance by guiding the discharge from the bucket. The solid turbine wheel has a reduced diameter rim portion and a full diameter rim portion such that the flow passageway may change in the relative radial displacement between the inlet and the discharge. An L-shaped passageway extending from the reduced diameter portion to the full diameter portion is utilized to obtain additional guidance of the flow as it is discharged from the turbine wheel to obtain improved performance.
