2. Biomass EnergyIndex:What is biomass energyHow plants make biomassConverting biomass to other forms of energyTypes of biomassAdvantages and disadvantages of biomassBiomass, a renewable energy 3. What is biomass?Biomass is organicmaterial madefrom plants andanimals(microorganisms). 4. How plants make biomass?Plants absorb thesuns energy in aprocess calledphotosynthesis.Biomass containsstored energyfrom the sun. 5. Converting Biomass to OtherForms of EnergyBurning biomass isthe only way torelease its energy,as heat. 6. Converting Biomass to OtherForms of EnergyThe heat produced by the burning of thewood is used to heat up the water. Thiswater then evaporates and transforms it intosteam. The water vapour (steam) under thehigh pressure, makes the turbine turn. Theturbine is connected to an electric devicecalled a generator, which, when it turns,produces electricity. 7. Biomass cycle 8. So,biomass can beburned to producesteam for makingelectricity, or toprovide heat toindustries andhomes too.Converting Biomass to OtherForms of Energy 9. Types of biomass 10. FirewoodThe most commonform of biomass isfirewood. Forthousands ofyears people haveburned wood forheating andcooking. 11. Pellets (briquetas)Pellets are madecreated bycompressing anoriginal material.Are use to burnthem in fireplace,heater... (have thesame use thatfirewood ) 12. CharcoalIs produced by theheating of woodandvegetable waste,until temperaturesbetween 400 and700 c, withoutoxygen.. 13. BiomassAdventagesIs a renawable,clean andecological energy.Is a inexpensivercombustible thanfossil fuels.DisadvantagesWhen burn themthey expel CO2,that contaminate. 14. Biomass is arenewable energysource because wecan always growmore trees andcrops.Renewable energy 15. By:Almudena RochaSara Matamoros 16. The End
