Abstract
The use of biogas as a renewable energy source has been widely applied to generation and cogeneration systems as an alternative to the fossil fuels. Hence, technical contributions in terms of performance parameters are always important to enhance the employed technologies, especially when they have to deal with a fuel of variable chemical composition. In this context, this paper presents experimental data about electrical generation system, constituted of a locally built power generator coupled to a spark ignition engine (SIE) burning biogas as the main fuel, performed in a test bed for SIE. Thus, the purpose of this study is to ensure that low power generator sets (<100 kW), using biogas can meet the requirements of environmental legislations in terms of pollutant emissions. The test bed employed in this study allows the variation of composition of biogas and measure the pollutant emissions produced by the combustion process. The preliminary results obtained with this study shows that there is a trade off between NOx emissions and CO/HC emissions. In addition, the methane consumption decreases as the content of CO2 increased in biogas.
