Diffuser of axial flow turbine generator and axial water turbine power generation device

摘要

Problem to be solved: to provide a diffuser of an axial flow turbine power generation apparatus capable of reducing a draft loss.Solution: the diffuser of the axial water turbine power generation apparatus according to the embodiment comprises a cylinder extending in the axial direction along the central axis of the draft tube and a flange portion provided in the cylinder. The flange portion is located downstream of the outlet end portion of the draft tube, and the direction of the water flow flowing through the outer periphery of the cylindrical body is directed away from the central axis.Diagram
