The Efficiency Analysis of Stirling Engine with Linear Generator Used in CHP Unit

Abstract

The aim of this paper is to present the possibilities of combined heat and power (CHP) using a Stirling engine with a linear generator. The laboratory tests of the CHP system with Stirling Engine were made, a control and measurement system was created, allowing to determine the most important electrical parameters. On the basis of the tests conducted, the obtained power of the linear generator, thermal power and system efficiency were determined. Computer simulations of the built-in control measurement system in the LabViewsoftware were performed and a magnetic flux in a linear generator made in the Finite Elements Method Magnetic program. The study can be used to develop a cheap and easy-to-manufacture a cogeneration system with the Stirling engine and to extend the use of alternative fuels to power the Stirling engine in public utility buildings
