Research Of Stirling Engine In Utilization Of The Low Grade Energy

The oil energy is reducing and its price is increasing day by day, the internal-combustion engine has brought environment pollution and broken zoology balance, the problems are standing out. Researching engine that can combust gas, marsh gas, biology is very signification that it can promote the compositive utilization of energy, change the use of only one oil energy, reduce environment pollution, create the economy society. According to the requirements on the development of energy and basing on the theory of stirling engine, the software the simulate stirling engine character is developed. Through its character, the stirling engine model is designed and manufactured, and it is tested, the conclusion consistent with the simulation character; It is proved theoretically that there are high thermal efficiency in combine circulation of stirling engine and other circulation (Rankine, Brayton). Finally, the combined cooling, heating and power system base on stirling engine that has energy conservation and economic is analyzed.
