Dish Stirling

Introduction to Technology

A Dish Stirling system is composed by a solar concentrator with high reflectivity, by a cavity solar receiver, and a Stirling engine, or microturbine that is attached to an alternator. The operation consists on heating a fluid located in the receiver until reaching a temperature approximate to 1382ºF (750ºC). Such energy is used to generate power by the engine or microturbine. For an optimum performance, the system should have the necessary mechanisms to perform solar tracking on two axles.

Dish Stirling Operating Scheme

2 Demonstration Plant:
Abengoa Solar NT has developed a dish Stirling structure, and installed 7 dishs Stirling of 10 KWe.

Development of a new concept:
Regarding large-size Stirling dishes for 25kWe (2 units) machines.
