1. Principles of Steam Turbines

Steam turbines operate based on the following principles:

?? Energy Conversion: Steam turbines convert thermal energy from high-pressure steam into mechanical energy through the expansion and acceleration of steam flow across turbine blades.

?? Expansion and Rotation: Steam enters the turbine at high pressure and temperature, expanding as it passes through fixed and rotating blades, causing the turbine rotor to spin at high speed.

?? Mechanical Work: The rotating turbine shaft is connected to a generator or mechanical load, converting the rotational energy into electrical power or mechanical work.

2. Components of Steam Turbines

Steam turbines consist of several key components:

?? Inlet Casing: The inlet casing directs steam into the turbine and houses the stationary blades, guiding the flow of steam towards the rotor.

?? Rotor: The rotor is the rotating component of the turbine, consisting of multiple stages of blades that extract energy from the steam flow.

?? Stator: The stator is the stationary component of the turbine, consisting of fixed blades that help redirect and control the flow of steam.

?? Governor System: The governor system regulates the speed and output of the turbine by adjusting steam flow and turbine blade angles based on load demand.
