Steam Cycle - an overview | ScienceDirect Topics
In regenerative steam Rankine cycles, steam is extracted from the turbines to preheat the boiler feedwater (BFW). This preheating process elevates the temperature at which the BFW receives heat, thus increasing the thermal efficiency of the plant (defined as the ratio between the net power output from and the heat input to the plant).

Steam Turbine Power Plants | Engaged in Thermodynamics
Steam Cycle. A steam cycle power plant is operated using the Rankine cycle. Water enters a boiler where it is heated to create steam. The steam is then sent through a steam turbine that rotates the shaft of a generator to create electricity. The steam exits the turbine into a condenser, which converts the steam back into saturated water.

Steam Engine. Steam enters the turbine with 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. In any type of steam engine, it is the VELOCITY of the liberated steam, and NOT the pressure, which produces the force which causes rotation of the shaft.
