SOLAR DISH ENGINE

Stirling Cycle: Stirling cycle engines used in solar dish/Stirling systems are high-temperature, high-pressure externally heated engines that use a hydrogen or helium working gas. Working gas temperatures of over 700 oC (1292ºF) and as high as 20 MPa are used in modern high-performance Stirling engines. In the Stirling cycle, the working gas is

α-Stirling hydrogen engines for concentrated solar power

In a Stirling engine, the working gas is compressed in the cold part and expanded in the hot part, thus converting heat into work. A regenerator is used to increase the efficiency of the process. A Stirling engine is made of heat sources, heat sinks, and various heat exchangers. Stirling engines are in principle efficient and environmentally ...
