摘要
A tube-cavity solar receiver was designed to obtain high temperature air for the micro gas turbine in a two-stage dish system. Experiments were conducted under both fair and counter currents with the inlet temperature of similar to 20 degrees C and the flow rate of 1 similar to 5m(3)/h. The average flux on the aperture was similar to 267 kW/m(2). Under the fair current situation, the outlet temperature ranged from 559 degrees C to 583 degrees C. Under the counter current situation, the outlet temperature ranged from 589 degrees C to 661 degrees C. The glass cover was proved useful for the receiver's performance.
