How is a turbine stage constructed

Webdesign of the turbine blade gives unidirectional rota-tion to the generator shaft. Hence, the turbines are called as ‘‘self-rectifying impulse turbine’’ or ‘‘bidirec-tional turbine’’. A bidirectional turbine needs guidevanes (GVs) placed up and down stream of the turbine blades or rotor blades (RBs). The bidirectional turbines ... WebAlthough several factors influence the formation of deposits on turbine components, the general effect is the same no matter what the cause. Adherent deposits form in the steam passage, distorting the original shape of turbine nozzles and blades. These deposits, often rough or uneven at the surface, increase resistance to the flow of steam.
