Introduction to Power Plants
- Power Plants are essential for electric power generation, crucial for industrial development.
- A country's power generation and consumption directly correlate with its development and standard of living.
- The generator is the primary equipment in a Power Plant, coupled with a prime mover to produce electricity.
Classifications of Power Plants
-
Conventional Sources (Non-renewable Energy):
- Steam Power Plant
- Hydroelectric Power Plant
- Diesel Power Plant
- Gas Turbine Power Plant
- Nuclear Power Plant
-
Non-Conventional Sources (Renewable Energy):
- Solar Power Plant
- Wind Power Plant
- Tidal and Wave Power Plant
- Ocean Thermal Energy Conversion
- Biomass Power Plant
- Geothermal Power Plant
Sources of Energy
-
Renewable Energy:
- Continuously available from natural processes and theoretically inexhaustible.
- Examples include Solar, Wind, Geothermal, Tidal, and Biomass Energy.
-
Non-renewable Energy:
- Finite resources expected to be depleted over time.
- Includes solid, liquid, and gaseous fuels, as well as hydraulic energy.
Types of Energy
-
Nuclear Energy:
- Generated via fission (splitting of atomic nuclei) and fusion (combining small nuclei).
- Nuclear energy is emission-free and a major energy source.
-
Thermal Energy:
- Associated with atomic motion; encompasses both kinetic and potential energy.
-
Chemical Energy:
- Released during chemical reactions, primarily through oxidation processes.
-
Radiant Energy:
- Exists across a spectrum of wavelengths from radio waves to gamma rays; converted to chemical energy via photosynthesis.
-
Mechanical Energy:
- The total of kinetic and potential energy.
- Potential Energy relates to an object's position in a force field, while Kinetic Energy is linked to its motion.
-
Electrical Energy:
- Arises from the movement of charged particles, particularly electrons.
Review of Thermodynamics Principles
-
Cycle:
- Refers to a series of processes returning to an initial state.
-
Vapor Power Cycle:
- Uses steam or water vapor as a working substance; combustion occurs in the boiler, differentiating it from internal combustion engine cycles.
