A SOLAR RECEIVER TO GENERATE AND REHEAT VAPOR BY SOLAR ENERGY

摘要

A tube panel having both vapor generating and superheating tubes. At least two parallel vapor generating tubes are spaced apart to provide a gap therebetween. A superheating tube is contiguous with each of the two vapor generating tubes and is disposed rearwardly of the gap to span the gap for receiving radiation energy from forward of the gap to assure a proper distribution of incident heat flux among the vapor generating and superheating tubes while eliminating the need for complex and expensive vibration support members for the vapor generating tubes. In accordance with a preferred embodiment, a support member is disposed rearwardly of and adjacent the superheating tube and extends transversely to the longitudinal direction thereof, and the vapor generating tubes are supported by tie bars connected between the respective vapor generating tubes and the respective support member to effectively support the superheating tube between the vapor generating tubes and the support member.
