- 1. outlines 1- introduction 2- biomass and its sources 3- the conversion of biomass energy 4- biomass power plant 5- advantages and disadvantages 6- economic benefits 7- conclusion
- 2. Biomass is the oldest source of energy
- 3. Farmers often burn their crop waste to get rid of it
- 4. INTRODUCTION Enough Biomass resources in the world to cover the world’s energy demand. Using Biomass sources for power generation is CO2 neutral.
- 5. INTRODUCTION
- 7. SOURCES OF BIOMASS Comes from the forest Can also come from plant and animal waste Wood and waste can be found virtually anywhere
- 8. The conversion of biomass energy
- 10. Pipes filled with water are heated to make steam Inside a biomass steam boiler Fire heats the water
- 11. 2-GASIFICATION gasification is a high-temperature (1200-1400 Degree Celsius)thermo chemical conversion process but the process is used for production of gas, instead of heat
- 12. GASIFICATION Biogas is produced by exposing biomass to high temperatures and limited oxygen. Biogas energy can serve as a feedstock for electricity generation or a building block for chemicals.
- 13. 3-PYROLYSIS . Heat is used chemically to convert biomass to bio-oil Pyrolysis oil : is easy to store and transportaion than solid biomass material and can be burned like petroleum to generate electricity Phenol oil : a chemical used to make wood adhesives, molded plastic and form insulation wood adhesives and used to glue together poly wood and then composite wood products
- 15. Biomass High Heat Boiler Steam Steam spins the turbine blades Turning Biomass into Electricity Rotating magnets create electricity
- 18. Combustion v.s gasification combustion Main advantage • Mature technology • Low running cost • Simple biomass pretreatment Disadvantage • Low efficiency at small scale • single biomass fuel • large investment Application • Large scale power generation gasification Advantage • High efficiency at small scale • Flexible in capacity • Low investment Disadvantage • Complex equipment • High maintenance cost Applications • Medium and small system • Combined cycles , which combine gas turbines and steam turbines to produce electricity
- 19. Advantages of biomass 1-Biomass is perennial source of renewable energy and it can be repeatedly grown and obtained as biomass. 2-Production of biomass not only gives fuels but it also gives good quality organic manures which when used in farms give bumper crops. 3-Methane gas produced from biomass is used as domestic fuel in gas stoves. 4-Biomass is available everywhere and no needs of any transportations.
- 20. Advantages of biomass 5-Methane gas can be used to run engines and generator and electricity can generate. 6-The biomass can be grown in near by seas and lakes. The lands can be spread for food crops. 7-I.C. Engines can be run on biogas produced from biomass. 8-Biomass can be used for plastics and pharmaceutical products. 9-Use of biomass keeps surroundings clean and healthy without insects and pests.
- 21. Disadvantages of biomass 1-Biomass contains 50-90% water and it is heavy. Hence transportation if needed is very difficult. 2-Direct combustion of biomass produces smokes and smells. 3-Calorific value of biomass if burnt in the raw form is very less. 4-Biogas plants need lots of care and maintenance for its successful operations. 5-It is economical if raw biomass such as cow dung is not freely available.
- 22. Disadvantages of biomass 6-Biomass conversion plants such as biogas are necessary to convert raw biomass into useful energy forms. 7-Biogas plants occupy larges land areas. 8-If the biomass is required to be transported over long distances, the cost transportaion is very high. 9-Biogas plants can’t be used in urban areas where the space availability is limited.
- 25. Biomass plants around the world
- 26. Economic benefits 1-Minimizes cost involved with waste disposal 2-Can generate money for community 3-It provide job opportunity in rural areas 4-Power from biomass gasifier based plants are cheap in rural areas 5-Overall cost of installation, running, transmission, labor etc. per unit cost of electricity is low.
- 27. conclusion 1- uses low cost waste materials 2- reduced dependence on foreign oil 3-convert biomass resources into liquid fuels and gaseous fuels 4- recycling waste material
