Abstract: At present, ecology is of primary concern. Looking for savings is an equally important factor forcing to implement innovative technologies. Many of industrial plants, devices and installations, heat energy is lost. An innovative solution is the use of Stirling engines for the use of waste heat energy. They can operate with relatively small temperature differences. Among the three configurations such as the alpha, beta and gamma types, the gamma type is very economical and simple in fabrication. So that we have decided to fabricate a gamma-type Stirling engine. We designed and fabricated a Gamma-type Stirling engine with rotary displacer for utilizing the waste heat in a cost for a better economy. Prior to the fabrication, the engine was modeled by using Autodesk Inventor. We used the parts of dumped machines for fabricating the Engine. The power piston which is used to extract the power from displacer cylinder is the compressor of a refrigerator. We have designed the engine to utilize the waste heat from the steam-boiler in our college. Similarly all the other components along with frame are dispatched from many other waste machines. This simple Engine can be easily fabricated and can be used for house-hold applications.

Keywords: Stirling engine, alpha, beta and gamma configurations, rotary displacer, waste heat management.
