摘要：

The　receiver,　whose　heat　loss　directly　affects　the　conversion　of　efficiency　from　optic　to　thermal,　is　a　key　component　of　the　parabolic　trough　collector.　By　analyzing　the　heat　loss　of　13　m　pipeline　which　is　constructed　by　six　two-meter　receivers,　the　results　show　that　the　radiant　heat　loss　is　70%　to　90%　of　the　total　heat　loss　when　oil＇s　temperature　from　105°C　to　313°C.　The　heat　loss　measured　by　quasi-static　equilibrium　method　is　larger　than　that　measured　by　steady-state　equilibrium　method,　and　at　high　temperature(290°C)　the　former　is　1.18　times　as　high　as　the　latter.　The　heat　loss　is　1.2　times　bigger　than　that　of　SCHOTT＇s　PTR70.　©　All　Rights　Reserved.
