Condensing steam turbines are used if the turbine is utilised solely for power generation i.e. it is connected to a generator and does not provide process steam to the plant. Unfortunately, the exhaust steam of condenser steam turbines must be condensed prior to being returned to the boiler (this is where condenser turbines obtain their name).

Read MoreThe Rankine cycle system consists of a pump, boiler, turbine, and condenser. The pump delivers liquid water to the boiler. The boiler heated by the solar heat converts water to superheated steam. This steam is used to run the turbine which powers the generator. Steam leaves the turbine and becomes cooled to liquid state in the condenser.

This correlates to thermal efficiencies ranging from 34 to 17% (HHV). Other than the 15 to 20% boiler efficiency losses and various minor losses in the turbine
Read MoreA boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Read MoreThe steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts
