Abstract

A solar heat receiver system includes multiple vertically extending solar heat receiving tubes for transferring solar heat to a heat transfer medium flowing through the solar heat receiving tubes, a rigid support structure, two first connectors to connect two spaced-apart portions of the solar heat receiving tubes to the rigid support structure so as to prevent horizontal movement of the two spaced-apart portions of the solar heat receiving tubes, and a second connector for connecting at least one intermediate portion of the solar heat receiving tubes to the rigid support structure, which intermediate portion is located between the spaced-apart portions. The second connector allows a limited amount of horizontal movement of the at least one intermediate portion of the solar heat receiving tubes due to a thermally induced bow of the solar heat receiving tubes.

Claims

exact text as granted — not AI-modified
1 . A solar heat receiver system comprising:
 multiple vertically extending solar heat receiving tubes having a length for transferring solar heat to a heat transfer medium flowing through the solar heat receiving tubes;   a rigid support structure;   two first connectors to connect two spaced-apart portions of the solar heat receiving tubes to the rigid support structure so as to prevent horizontal movement of the two spaced-apart portions of the solar heat receiving tubes; and   a second connector for connecting at least one intermediate portion of the solar heat receiving tubes to the rigid support structure, which intermediate portion is located between the spaced-apart portions, wherein the second connector allows a limited amount of horizontal movement of the at least one intermediate portion of the solar heat receiving tubes due to thermally induced bow of the solar heat receiving tubes.   
     
     
         2 . The solar heat receiver system according to  claim 1 , wherein the allowed horizontal movement is at most 1% of the length of the solar heat receiving tubes. 
     
     
         3 . The solar heat receiver system according to  claim 2 , wherein the allowed horizontal movement is at most 0.5% of the length of the solar heat receiving tubes. 
     
     
         4 . The solar heat receiver system according to  claim 1 , wherein the second connector allows vertical movement of the at least one intermediate portion of the solar heat receiving tubes induced by thermal expansion of the solar heat receiving tubes. 
     
     
         5 . The solar heat receiver system according to  claim 1 , wherein the second connector is made by having fixing means in a horizontally extending slot, so as to allow a limited amount of free horizontal movement of the at least one intermediate portion of the solar heat receiving tubes. 
     
     
         6 . The solar heat receiver system according to  claim 1 , wherein the second connector is made by parallel plates and gaps, so as to allow a limited amount of free horizontal movement of the at least one intermediate portion of the solar heat receiving tubes. 
     
     
         7 . The solar heat receiver system according to  claim 1 , wherein the second connector is flexible so as to allow restrained horizontal movement of the at least one intermediate portion of the solar heat receiving tubes. 
     
     
         8 . The solar heat receiver system according to  claim 1 , wherein the second connector allows more horizontal movement outwards than inwards. 
     
     
         9 . The solar heat receiver system according to  claim 1 , wherein the second connector allows horizontal movement only outwards. 
     
     
         10 . The solar heat receiver system according to  claim 1 , wherein the second connector is more flexible to horizontal movement outwards than inwards. 
     
     
         11 . The solar heat receiver system according to  claim 1 , wherein the two spaced-apart portions of the solar heat receiving tubes and the at least one intermediate portion of the solar heat receiving tubes are on a same linear portion of the solar heat receiving tubes. 
     
     
         12 . The solar heat receiver system according to  claim 1 , wherein the two spaced-apart portions of the solar heat receiving tubes are horizontally displaced from the at least one intermediate portion of the solar heat receiving tubes by bent portions of the solar heat receiving tubes. 
     
     
         13 . The solar heat receiver system according to  claim 1 , wherein the solar heat receiver system is a superheater or a reheater.
