Title: BIOMASS ENERGY International Renewable Energy Youth Competition


1
BIOMASS ENERGYInternational
Renewable Energy Youth Competition
  • Una Pale Omri Danziger Avishai Ketko

2
biomass
  • renewable energy resource
  • biological material from living, or recently
    living organisms
  • based mostly on carbon, hydrogen and oxygen

3
getting the energy from biomass
  • energy in form of
  • heat, current, methane, transportation fuel
    ethanol, biodisel
  • combustion
  • burning organic material
  • pyrolysis
  • thermochemical decomposition of organic material
    at elevated temperatures in the absence of oxygen
  • gasification

4
gasification
  • biomass
  • clean and combustible gas (syngas)
  • reacted with controled amount of steam and air
    at high temperature
  • product gases CO, H2, CO2, CH4

5
equation
  • incomplete combustion of hydrocarbons
  • products H2, CO, CO2, CH4, H2O and
  • un-burnt carbon

6
our idea
  • mirrors instead of woods
  • higher temperature
  • more gas (fuel)
  • less pullution
  • less wood wasted as a feedstock for heating the
    furnace

pictures of our idea
7
energy transformation
  • energy from the sun
  • solar energy
  • biomass plants, woods, algaes chemical energy
  • air and steam
  • sunlight
  • reflection on mirrors
  • focused on the furnace
  • heat

gasification
combustible gases H2, CO
fuel biodisel, ethanol
8
  • conditions needes
  • in the furnace the same
  • outdoor conditions sun
  • economic consideration
  • cheaper
  • getting more gas (fuel)
  • future
  • solar focus technology will improve
  • enhance the eficiency of the process
  • no environment impact
  • no releasing CO2 into the atmosphere
  • heating with the sun no impact

9
biomass in dead trees
  • Advantages
  • no need to cut down trees
  • the trees are dried biomass
  • Dissadvantages
  • water is needed
  • the trees could be far away
