2. “Now is the time for
change. We cannot
drill our way out of
energy crisis. The era
of fossil fuels is over.
We must invest in
renewable energy.
And we must not
delay.” – Lewis

8. pyrolysis
• The thermal
destruction of
biomass in
anaerobic
environment
• Combustion
occurs in gas
turbine
typically
• Requires more
process control
and
investment
• Partly Oxidized
by controlled
oxygen and
steam
• Product gases
have high
calorific value
• Requires more
process control
and investment
• Complete
combustion In
excess air
• Flue gas is used
to convert
process water to
steam
• Oldest, simplest
but most
inefficient

9. Pyrolysis- 4-10 cents/kWh
Gasification- 4-16 cents/kWh
Combustion- 3-12 cents/kWh

19. Reduce emission of
Sulfur and sulfur compounds by 4.5%
Nitrogen compounds by 6 %
19
Negative impacts on forest management and
farming
High levels of water
use
20. Advantages of biomass plants
Biomass crops
are sustainable
and can be
grown anywhere
Produces lower
level of CO2
than fossil fuel
Emission of
harmful gases
is lower than
fossil fuel
It takes in CO2
and releases O2
Available and
renewable.
Products can be
used in cyclic way
Reduces landfill.
Harmful products
converted to useful
ones

21. Disadvantages of biomass
plants
Reduction in
growth of basic
crops for eating
purpose
Relatively
larger land is
needed
High operation
and production
cost
Inefficient as
Compared to
Fossil Fuels
Harmful to
Environment
Emission of CO2
and volatile
compounds in air
