Testing of the STM4-120 kinematic Stirling engine for solar thermal electric systems

摘要

The STM4 120 is being bench-tested at Sandia's engine test facility and will be combined later with a solar receiver for on-sun evaluation. The test system layout, instrumentation, controls, testing parameters, and preliminary performance results for the STM4-120 are presented. Ten hours of operation have been carried out and used to check out the facility. These preliminary results indicate that the engine is performing to specifications.
