Determination of appropriate operational parameters of a floating–drum biogas plant for rural Nigeria
This paper determined the appropriate operational parameters of a floating–drum biogas plant that give the highest gas production rate (m³/h), best gas quality (% methane fraction) and required output pressure (mbar) for burners. The operational parameters were retention time and weight on the floating drum of the plant. The retention times of 15, 20, 25, and 30 days, and weights of 50, 100, 150 ...

CHP efficiency for biogas
Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to produce electricity. Heat is released during the gas ...

Using biogas for combined heat and power
An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs of the installation. However, the engine is integral to the plant, and is the key component in the production of renewable electricity, hence the ...
