Bio Power means the generation of electricity or thermal from biomass resources.
Technologies for obtaining power from biological sources include direct combustion, co-firing and anaerobic digestion.
Most of the electricity produced from biomass is produced by direct combustion using conventional boilers. These boilers burn mainly wood waste from agriculture and from wood processing industry. When burning, wood produces steam that spins a turbine. The turbine spins and activates a generator that produces electricity.
Co-combustion / co-firing
Co-firing involves replacing a portion of a high efficiency oil-based fuel from the boilers, with biomass. Co-firing has proved successful in most boilers based technologies, including pulverized coal, cyclone, fluidized bed and Stoker spread units. Biomass co-firing can significantly reduce sulfur dioxide emissions of coal-fired power plants and is an option with the lowest cost of the technologies that produce renewable energy.
Anaerobic digestion or methane recovery is a common technology used to convert organic waste into electricity or thermal. In anaerobic digestion, organic material is decomposed by bacteria in the absence of oxygen thus producing methane and other bioproducts, which forms a natural renewable gas.
