Model-based research on a micro cogeneration system with Stirling engine

One of the elements and purposes of the climate-energy policy of the European Union is to increase the efficiency of conversion of the energy from fossil fuels. Managing high-temperature heat losses which accompany the technological processes, especially in thermal power engineering, serves this goal. An example of effective use of this heat is through the application of distributed generation devices (including: fuel cells, microturbines, and Stirling engines), which produce in combination electric energy, or mechanical energy and heat. This paper presents research into a micro cogeneration system with a Stirling engine, using nitrogen as a working gas. A crucial element of the research is model-based analysis of changes in selected thermodynamic parameters, including among others: pressure change in the working cylinder. The presented comparison of the research results, as well as the results of simulation, effectively support the prediction processes as regards the system.
