What does biogas mean?
Gas mixture (methane, carbon dioxide, etc.) produced by anaerobic fermentation in the presence of microorganisms (acidogenic&acetogenic bacteria, and methanogens) in agricultural by-products or industrial waste, or mud from treatment of urban waste water. Methane contained in biogas can be used for production of energy or heat.Formation of gas by anaerobic fermentation in the presence of microorganisms (acidogenic&acetogenic bacteria, and methanogens) in agricultural by-products or industrial waste, or mud from treatment of urban waste water. Methane contained in biogas can be use for energy production.
What does an Anaerobic fermentation plant or energy and heat production comprise?
A biogas cogeneration system comprises two parts: one for fermentation and production of biogas, which includes one or more fermenters, and the other to transform biogas into energy, which the actual cogeneration system. Biogas is a mixture primarily made up by methane, carbon dioxide, and other minor components, which is obtained from anaerobic fermentation induced by digesters.
Biogas is properly treated to power the endothermic engine of a cogeneration plant. The cogeneration phase produces electrical and thermal energy. The first is destined to be sold to electricity distribution networks at predetermined rates; the second is primarily used to allow digesters to maintain their ideal fermentation temperature.
