The use of biogas and sewage gas generated in digesters is well established technology. Organic waste is processed and the resultant gas is collected in a large accumulator to smooth out fluctuations in production. This is then either fed into the gas generator or excess burnt in a high temperature flare should the generator be offline.
Heat recovered from the generator (CHP) can then be used to keep the digester at optimal temperature for further gas production, or if present, it can be utilised by an alternative local heat load, completing what is an extremely efficient energy cycle. Whilst containing approximately 60% CH4, some contaminants are present within this fuel, and are generally a result of the waste materials fed into the digester, these however can be isolated or treated using advanced filter techniques before combustion.
Today’s biogas generators are designed to cope with the varying methane content and different levels of impurities found in this fuel. They will perform reliably with efficiencies near that of natural gas engines. Service intervals and oil changes are fine tuned to suit specific sites and individual waste streams.
Whether you are involved in waste water treatment plants (WWTP) or the digestion of organic matter in anaerobic digestion (AD), Yellow Power Ltd have considerable experience in the design of biogas generation plant, and can package generators and heat recovery plant to suit.
