Steam Turbine
• Steam turbines drive electricity generation by
converting high-pressure steam's thermal energy into
mechanical work through a rotating rotor, following
the Rankine cycle. This rotation powers an electric
generator, transforming the mechanical energy into
electrical power in power plants.

4. 4
Description of each components
• Boiler, The boiler is where water is heated to produce high-pressure steam. It is typically
fueled by coal, natural gas, or oil. The heat generated by burning the fuel is transferred to
the water, raising its temperature and pressure.
• Turbine, The turbine is the main component of the power plant where the high-pressure
steam expands and converts its thermal energy into mechanical work. It consists of
stationary and rotating blades arranged in stages. The steam flows over the blades, causing
the rotor to rotate. The rotation is used to drive the electric generator
• Generator, The generator is coupled to the turbine rotor and converts the mechanical
energy from the turbine into electrical energy. It consists of a rotating rotor and stationary
stator windings. As the rotor rotates, it induces a magnetic field in the stator windings,
generating electricity
• Condenser, In a condensing turbine, the steam exhausts from the turbine into a condenser.
The condenser is a heat exchanger that cools and condenses the steam back into water by
transferring heat to a cooling medium, such as cooling water from a nearby water source.
The condensed water is then pumped back to the boiler for reheating.

5. 5
• Cooling Tower, Power plants require a cooling system to dissipate the waste heat generated during
the power generation process. This can be achieved through various methods, such as cooling
towers, where warm water from the condenser is sprayed and cooled by air, or through the use of
natural bodies of water.
• Pump, In a steam power plant, pumps are crucial for circulating water. They help feed water to the
boiler, assist in maintaining proper pressure, and circulate cooling water in some systems. Pumps
play a vital role in the overall efficiency of the power generation process
• Water treatment plant for steam power plant, Water treatment is essential in a steam power
plant to prevent scale, corrosion, and impurities that could damage equipment. The treatment
involves processes like demineralization, filtration, and chemical conditioning to ensure the boiler
and other components operate efficiently and have an extended lifespan. Proper water treatment
also contributes to maintaining high heat transfer rates and overall system reliability

Case study, reference case:
Consider a steam power plant operating on the actual Rankine cycle. Steam enters the turbine at 3 MPa and
600°C and is condensed in the condenser at a pressure of 10 kPa. The isentropic efficiency of pump and
turbine are respectively 0.85 and 0.8. Determine the thermal efficiency of this power plant.

1- Effect of boiler pressure on the performance of steam Turbine cycle
Consider a steam power plant operating on the actual Rankine cycle. Steam enters the
turbine at P2 variable parameter and 600°C and is condensed in the condenser at a
pressure of 10 kPa. The isentropic efficiency of pump and turbine are respectively 0.85
and 0.8. Determine the thermal efficiency of this power plant.
1. Draw the thermal efficiency of this steam-turbine cycle function of the boiler pressure

Dissuasion:
Elevating boiler pressure enhances thermal efficiency by
reducing the heat input to the boiler lowering energy costs and
increasing the work net. It's important to note that, with a
constant turbine inlet temperature, this adjustment shifts the
cycle to the left, resulting in higher moisture content in the
steam at the turbine exit

2- Effect of turbine inlet temperature on the performance of steam turbine cycle
Consider a steam power plant operating on the actual Rankine cycle. Steam enters the
turbine at 3MP and T3 variable parameter and is condensed in the condenser at a
pressure of 10 kPa. The isentropic efficiency of pump and turbine are respectively 0.85
and 0.8. Determine the thermal efficiency of this power plant.
1. Draw the thermal efficiency of this steam-turbine cycle function of the inlet turbine
temperature.( minimum 6 values of temperature)
2. Discuss the results.

800 ℃ 0.326

19. 19
Discussion:
Increased turbine inlet temperature contributes to improved thermal
efficiency. Raising steam temperature through superheating is
beneficial as it reduces moisture content in the steam at the turbine
exit. It's essential to note that metallurgical considerations impose
limitations on the extent to which steam can be superheated

• In summary, steam turbine power plants have been
crucial for large-scale electricity generation, converting
thermal energy into mechanical energy efficiently.
However, environmental concerns are driving a shift
towards cleaner and sustainable alternatives,
emphasizing the integration of renewable energy
sources and advanced technologies for a more
environmentally friendly power generation landscape.
