What is Steam Turbine – Description and Characteristics. In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or electrical energy. A steam turbine consists of a boiler ( steam generator ), turbine, condenser, feed pump, and various auxiliary devices in its simplest form.

2.3 Boiler and steam cycle model. In the steam cycle shown in Figure 1, the pressure of the feed water increases to 2 atm by Pump 1. The feed water entering the deaerator is further preheated to 127 °C by the steam at 159 °C and 6 atm coming from the turbine extraction valve. The pressure of the preheated feed water rises to 67 atm by Pump 2.

The function generator accepts the command from the bridge, which may be in the form of a step function, and converts it into a command which is compatible with the boiler/turbine assembly. The output of the function generator is applied to the speed controller as a desired value which is then compared with a measured variable obtained from the speed sensor driven by the main shaft.
