Benji and Harishan's presentation of energy from biomass. Packed with information, a really great presentation. Made as part of 2R's project on renewable energy.
2. What is biomass Biomass is biological material derived apply from living, or recently living organisms. In the context of biomass for energy this is often plant based material, but biomass can equally to both animal and vegetable derived material used to mean
3. Examples Wood Trees Shrubs Wood Residue Sawdust, bark, etc. from forest clearings and mills Wastes Municipal Solid Waste (MSW) Paper, food and yard wastes, platics, wood, and tires Livestock Waste Process Waste Sewage Crops Starch crops Corn, wheat, and barley Sugar crops Cane and beet Forage crops Grasses, alfalfa, and clover Oilseed crops soybean, sunflower, safflower Aquatic Plants Algae Water weed Water hyacinth Reed and rushes
4. More information for now. The biomass is a material from plants and animals it can be used as an energy ressources the energy in the biomass comes from the sun. The plants trap the suns energy to make the food and grow. The animals eat the plants or the animals that ate plants. We produce a lot of rubbish that can be rotted to make methane. We can replace biomass as we use it. The biomass burns in the boiler of the power station burning gives out thermal energy that heats water and turn it into steam. The steam turns the turbine which turns the generator and makes electricity.
5. It makes sense to use waste materials where we can. The fuel tends to be cheap. Less demand on the fossil fuels. adavantages on biomass Dry biomass can be grown on a large scale in the form of: wheat oats barley oilseed cake
6. Disadvantages Collecting or growing the fuel in sufficient quantities can be difficult. We burn the biofuel, so it makes greenhouse gases just like fossil fuels do. Some waste materials are not available all year round.
