Free Piston Stirling Engines pp Cite as. A Stirling engine is a mechanical device which operates on a closed regenerative thermodynamic cycle with cyclic compression and expansion of the working fluid at different temperature levels.
The demand for better hygiene has increased the need for developing more effective sanitation systems and facilities for the safe disposal of human urine and faeces. Non-Sewered Sanitary systems are considered to be one of the promising alternative solutions to the existing flush toilet system. An example of these systems is the Nano Membrane Toilet NMT system being developed at Cranfield University, which targets the safe disposal of human waste while generating power and recovering water. The NMT will generate energy from the conversion of human waste with the use of a micro-combustor; the heat produced will power a Stirling engine connected to a linear alternator to generate electricity. This study presents a numerical investigation of the thermodynamic analysis and operational characteristics of a quasi steady state model of the gamma type Stirling engine integrated into a combustor in the back end of the NMT system.

Status of the emerging technology of Stirling machines Abstract: The commercialization status of Stirling machines varies from established niche market products to potential products that are in early stages of development. In other words, we are talking about a typical emerging technology. Many organizations are actively pursuing product development based on Stirling machine technology. Stirling machines offer significant performance advantages, but many obstacles remain to be fully resolved, including cost and demonstrated reliability.
This article describes the technology upon which Stirling machines are based. Several application areas are then explored, including hot air engines, remote power, solar thermal power, sensor cooling, refrigeration, cogeneration and air-independent propulsion. Article :.

A 35 kW el pilot plant was put into operation in and was successfully tested for more than 10, hours. A second pilot plant with a 70 kW el engine is in operation since autumn The newly developed CHP technology can be considered as a breakthrough in the application of Stirling engines for small-scale CHP plants burning solid biomass fuels. A field test with seven 35 kW el engines has been initiated and first demonstration plants were put into operation in summer The Biomass CHP technology based on Stirling engine is in demonstration phase and not available on the market at the moment. It is expected that this technology will be commercially available within the next few years. Stirling engines are based on a closed cycle, where the working gas is alternately compressed in a cold cylinder volume and expanded in a hot cylinder volume.
The history of hot air engines is years old. It began in , when Robert. Stirling invented the first one . Fifty years later James Watt built his steam engine.
ASME Press, In open-cycle engines mechanical work is performed by a quantity of working fluid which is made to undergo successively certain operations, such as induction, compression, heating, expansion, and exhaust.
