This presentation is about thermalpower plant.

1. POWER GENERATION

2. Law of energy conversion
The law of conservation of
energy states that energy can
neither be created nor
destroyed - only converted
from one form of energy to
another.

3. Types of power plants
Nuclear power plants.
Hydroelectric power plants.
Coal-fired power plants.
Diesel-fired power plants.
Geothermal power plants.
Gas-fired power plants.
Solar power plants.
Wind power plants.

5. Thermal Powerplant
A thermal power station is a power station in which heat
energy is converted to electricity
Typically, heat is used to boil water in a large pressure
vessel to produce high-pressure steam, which drives a steam
turbine connected to an electrical generator.
In coal-fired power plants, bituminous coal, subbituminous
coal, or lignite is burned. The heat produced by the
combustion of the coal is used to convert water into high-
pressure steam, which drives a turbine, which produces
electricity.

6. Thermal Powerplant
Lignite is used in thermal power stations since it
is of lower grade and contains less percentage of
carbon.
Lignite is defined as non-agglomerating coal with
a gross calorific value on moist ash free
basis <4165 kcal/kg.

8. Geothermal power plants use hydrothermal resources that have both water
(hydro) and heat (thermal). Geothermal power plants require high-temperature
(300°F to 700°F) hydrothermal resources that come from either dry steam wells
or from hot water wells.
