摘      要：Parabolic through concentrators and parabolic dish concentrators followed by a PVR (pressurized volumetric receiver) are proposed, studying the performance behavior of a RCBC (regenerative closed Brayton cycle) operating with helium or hydrogen. A pressurized gas such as helium circulates along the volumetric receiver, capturing the concentrated thermal solar energy to be further converted into electric power via a thermal cycle. The overall efficiency of the plant has been computed under variable parameters to determine the operating conditions for which efficiency and specific power are acceptable. As consequence of the proposed analysis, it is concluded that direct coupling between volumetric receivers and thermal engines renders high efficiency while avoiding an intermediate heat transfer medium.
