槽式 DSG 太阳能热发电集热管传热特性探讨

摘要

A one-dimensi nal model was built according to the principle of conservation of energy.Heat-coll ct ng efficiency of solar collector tubes under different working conditions was analyzed.An approach to computational methods of outlet temperature and outlet dryness of solar collector tubes was provided based on a two-dimensional model.Outlet temperature and outlet dryness of 24-meter-long solar collector tubes under different working conditions were analyzed.The essay could be reference for future construction of DSG trough type solar energy collection hot power station.%　　本文运用能量守恒的方法建立了集热管一维模型，分析了集热管在不同工况下的集热效率，同时建立二维模型给出了集热管出口温度和出口干度的计算方法，分析了24米长集热管在不同工况下的出口温度和干度，为今后建立槽式 DSG 太阳能热集热发电站提供参考意见。
