Question:

Solar One is the first large-scale (10 MW electric) solar-thermal electric-power-generating plant in the U.S. It is located near Barstow, CA. A schematic diagram of the receiver and tower is shown below (the heliostat, i.e., mirror field, is not shown). The receiver may be treated as a cylinder 7 m in diameter and 13.5 m tall. At the design operating conditions, the average outer surface temperature of the receiver is about 675?C and ambient air temperature is about 40?C. Estimate the rate of heat loss, in MW, from the receiver??via natural convection only??for the temperatures given. What are other mechanisms by which heat may be lost from the receiver?GIVENA vertical cylinder in airHeight of cylinder (L) = 13.5 mDiameter (D) = 7 mSurface temperature (Ts) = 675?CAmbient air temperature (T??) = 40?CASSUMPTIONSAir is stillSurface temperature is uniform andconstant
