Low pressure steam turbine with multi channel diffuser

The axial/radial three-passage diffusor of the LP steam turbine has two deflector plates (8,9) which extend over the diffusor's whole length and are distributed between an inner diffusor ring (4) and outer diffusor ring (5) so that the surface distribution to the three diffusor sections (10-12)...

Zusammenfassung:The axial/radial three-passage diffusor of the LP steam turbine has two deflector plates (8,9) which extend over the diffusor's whole length and are distributed between an inner diffusor ring (4) and outer diffusor ring (5) so that the surface distribution to the three diffusor sections (10-12) in the intake area is unequal. A large part of the flow intake area of the whole diffusor is allotted to the inner and center sections, and a smaller part to the outer section.
