Options Which Shall Be Considered for Buying a Steam Turbine

2 Options Which Shall Be Considered for Buying a Steam Turbine 

Condensing-type turbine—This is used only for power generation. All (or maximum quantity available of) the steam is passed through this turbine and the exhaust steam is fully condensed to maintain as low a pressure at the exit as possible. This maximises the power generated. The exhaust steam from this type of turbine is at very low pressure and temperature, hence cannot be used for process heating. 

Following properties of steam and condensate are considered for these four cases. 

The steam from the exit of the turbine is condensed by the cooling water, and the latent heat energy is thus not available. 

Case 3 Back-pressure turbine, steam superheated to 300 C
