What is biomass?
Biomass is organic
material made
from plants and
animals
(microorganisms).
How plants make biomass?
Plants absorb the
sun's energy in a
process called
photosynthesis.
Biomass contains
stored energy
from the sun.
Converting Biomass to Other
Forms of Energy
Burning biomass is
the only way to
release its energy,
as heat.
Converting Biomass to Other
Forms of Energy
The heat produced by the burning of the
wood is used to heat up the water. This
water then evaporates and transforms it into
steam. The water vapour (steam) under the
high pressure, makes the turbine turn. The
turbine is connected to an electric device
called a generator, which, when it turns,
produces electricity.
Biomass cycle
So,biomass can be
burned to produce
steam for making
electricity, or to
provide heat to
industries and
homes too.
Converting Biomass to Other
Forms of Energy
Types of biomass
Firewood
The most common
form of biomass is
firewood. For
thousands of
years people have
burned wood for
heating and
cooking.
Pellets (briquetas)
Pellets are made
created by
compressing an
original material.
Are use to burn
them in fireplace,
heater... (have the
same use that
firewood )
Charcoal
Is produced by the
heating of wood
andvegetable waste,
until temperatures
between 400 and
700 ºc, without
oxygen.
.
Biomass
Adventages
●
Is a renawable,
clean and
ecological energy.
Is a inexpensiver
combustible than
fossil fuels.
●
Disadvantages
●
When burn them
they expel CO2,
that contaminate.
Biomass is a
renewable energy
source because we
can always grow
more trees and
crops.
