“…There is 50.5% of the energy absorbed by water/steam for the central panel while 24.9% and 24.6% for the right side and the left side panel respectively. The simulation data agree reasonably well with the experimental data of CESA-1 receiver (Baker et al, 1989), which also shows 48% of the energy absorbed by the central panel and 26% by each side one.

“…And the distribution of incident solar flux has a great effect on the temperature distribution inside the receiver. CESA-1 cavity receiver, a demonstration power station in Spain, was introduced by Baker et al (1989). In their report, receiver controls, locations based on analogic measurements, cold and warm receiver start-ups, and transient response to cloud-induced changes were mentioned as the influential elements on the operation of CESA-1.…”

The pioneering water/steam cavity receiver CESA-1 is not very successful for that the evaporator and superheater are in the same cavity cause it is very difficult to control the heat flux distribution on the absorber surface and hence the flow stability inside the receiver. The two-stage water/steam receiver is a promising way for separating the evaporator and superheater in two different cavities or parts. Because the two different parts have different thermal performance, the required concentration ratio(CR) of per heliostat projected two different parts will be different. Based on the transient efficiency equation and existed DAHAN solar tower power plant, the paper research the influence principle of many factors such as receiver thermal performance, superheater operation capacity, heliostat size and numbers of heliostats projected to the absorber. The results show that the required CR of per heliostat for superheat part is decreasing with the superheater thermal performance improving. When the receiver operates in lower capacity, the required CR of per heliostat is lower. With more heliostats project to the superheater, the required CR of per heliostat becomes lower. The smaller heliostat size, the lower required CR of per heliostat. The results also give us some inspirations that: 1) using the method in the paper, one can evaluate whether the existing heliostat field is fit for the two-stage receiver. 2) two stage receiver capacity and heliostat size should be in harmony for different CR requirement for evaporator and superheater. 3) the results about how the heliostat size influences the required CR of per heliostat for superheater give the reference to industrial choose of heliostat size. 4) from the required CR point, the smaller heliostat is better than bigger one. Of course, in the real commercialization process, the cost of the heliostat should also be considered.

“…The second is that, some results of Spanish CESA-I tower plant are taken to test the precision of our developed model. The size, shape and coordinates of each heliostat in the heliostat field and the geometry of the cavity-type receiver are input into our model to make a comparison with the published data by the CESA-I plant [17,18]. The final comparative results were published and analyzed in detail in our previous paper [12].…”
