Powerplants lecture

1. Coal, Natural gas and
Nuclear Powerplant

2. Coal Powerplant

3. Coal Powerplant
 Now that clean coal technologies are available,
the demand for coal has remained steady
despite the current stringent standard on
environmental concerns. The Philippines is
largely a coal consuming country
with coal having the highest contribution

4. Advantages and disadvantages of coal
powerplant
Advantage
• Coal is the most abundant energy source. There is
no shortage of coal and foreign political turmoil
does not interrupt the flow of coal.
• Modern plants are very efficient in terms of
producing copious amounts of electrical power from
raw fuel.
• Power plants are prevalent and the technology is
mature.
Disadvantage
• Air pollution that can cause asthma,
cancer, heart and lung diseases,
neurological problems, acid rain, and
global warming.
• Radiation exposure that can be up to
100 times higher than a nuclear
power plant.
• Mercury, nitrous oxide, heavy metals,
and other toxic substances that can
harm wildlife and ecosystems.

5. The top countries that use coal power plants are:
• China
• India
• United States
• Japan
• Indonesia

6. Natural Gas Powerplant

7. Natural gas powerplant
A gas-fired power plant, sometimes
referred to as gas-fired power station
or natural gas power plant, is a
thermal power station that burns
natural gas to generate electricity.
Gas-fired power plants generate
almost a quarter of world electricity
and are significant sources of
greenhouse gas emissions.

8. Advantages and disadvantages of Natural
Gas Powerplant
Advantages
• Cheap and quick to build
• Have very high thermodynamic
efficiencies
• Produce fewer pollutants like
NOx, SOx and particulate matter
than coal and oil
• Are better able to meet
fluctuating demand
Disadvantages
• Highly inflammable
• Non-renewable source of
energy and will eventually die
out
• Polluting water and earth
• Greenhouse gas emissions
• Leakage

9. The following countries have natural gas power stations:
• United States
• Russia
• China (Mainland)
• Germany
• Italy

10. Nuclear Powerplant

11. Nuclear Powerplant
 A nuclear power plant (NPP) is a
thermal power station in which the
heat source is a nuclear reactor. As is
typical of thermal power stations,
heat is used to generate steam that
drives a steam turbine connected to a
generator that produces electricity.

12. Advantages and disadvantages of Nuclear
Powerplant
Advantages
• Low-carbon energy source
• Small carbon footprint
• Reliable and cost-effective
• Economical and require less land
than other forms of energy production
• Provide a clean form of energy with
no greenhouse gas emissions
Disadvantages
 High capital cost and long approval and
commissioning time
 Non-renewable and depleting source of uranium
 Disposal and storage of nuclear waste, which is
radioactive and highly toxic
 Accidental leakage of radiation and large-scale
accidents, which can be catastrophic
 Security risks of nuclear waste falling into the wrong
hands
