Abstract
The spread of renewable resources is becoming the key to the advancement of new technologies for power generation. Stirling engine has become subject of interest due to its ability to obtain high thermal efficiency and its versatility, allowing the insertion of different sources of heat, which is transformed into useful work. One of the sources used in Stirling cycle is biogas. A better use of generated biogas from the decomposition of organic waste is to reduce the emission of methane and carbon dioxide gases in atmosphere, which is actually an environmental issue. Therefore, the goal of this paper is to develop a methodology to project a system capable to produce biogas to a Stirling engine. In order to do this, some important parameters to be estimated are: biogas flow rate, volume of biogas to work 24 hours per day, biodigester sizing and the correct quantity of animals that gives the total biomass to be digested. Some Stirling engines present in the literature were used as a basis of this work, making possible a socioeconomic viability study of this proposal. The results show that the use of biogas in Stirling engines can be implemented in the Brazilian agriculture, giving destination to the organic waste that normally are been thrown away.
