The present experimental work was carried out on a live plant at Sultanate of Oman for enhanced crude oil recovery by steam injection. The plant mainly consists of Glasshouse enclosed Parabolic Trough Collectors for direct steam generation at large scale. Energy performance aspects and losses occurred during the energy conversion were assessed in detailed for an evaporator loop of the plant. It was explored that the overall efficiency and losses of the installation are in the range of 46–56% and 44–54%. Energy received from the sun was in the range of 4800–6150 kW. Useful energy for steam generation varied between 2420 and 3210 kW. The maximum energy loss due to the glasshouse enclosure was about 460 kW. Similarly, radiation concentration and thermal losses were in the range of 1060–1480 kW and 480–520 kW, respectively. Both the quality and quantity of the steam generation increased significantly with increasing solar irradiation. As the energy losses occurring due to solar radiation concentration on to the receiver tubes were higher than all other kinds of losses, design parameters of trough need to be optimized in view of incidence angle, shadowing effects, and tracking errors. Detailed thermal efficiency and energy loss analysis could support to overcome the design challenges and find the opportunities for further optimization in design and development and eventually helps to reduce high capital cost for Glasshouse Enclosed Parabolic Trough installations.

目前的实验工作是在阿曼苏丹国一个有生命的工厂进行的，目的是通过蒸汽注入提高原油采收率。该工厂主要由玻璃温室封闭的抛物槽收集器组成，可直接产生大量蒸汽。针对工厂的蒸发器回路，详细评估了能量性能方面和能量转换过程中发生的损失。研究发现，安装的总体效率和损失在46–56％到44–54％的范围内。从太阳接收的能量在4800-6150 kW之间。产生蒸汽的有用能量在2420到3210 kW之间变化。温室外壳造成的最大能量损失约为460 kW。同样，辐射集中度和热损失分别在1060–1480 kW和480–520 kW之间。随着太阳辐射的增加，蒸汽产生的质量和数量均显着提高。由于由于太阳辐射集中在接收管上而产生的能量损失高于所有其他种类的能量损失，因此需要根据入射角，遮蔽效应和跟踪误差来优化槽的设计参数。详细的热效率和能量损失分析可以帮助克服设计难题，并找到进一步优化设计和开发的机会，并最终帮助减少Glasshouse封闭式抛物槽安装的高投资成本。由于由于太阳辐射集中在接收管上而产生的能量损失高于所有其他种类的能量损失，因此需要根据入射角，遮蔽效应和跟踪误差来优化槽的设计参数。详细的热效率和能量损失分析可以帮助克服设计难题，并找到进一步优化设计和开发的机会，并最终帮助减少Glasshouse封闭式抛物槽安装的高投资成本。由于由于太阳辐射集中在接收管上而产生的能量损失高于所有其他种类的能量损失，因此需要根据入射角，遮蔽效应和跟踪误差来优化槽的设计参数。详细的热效率和能量损失分析可以帮助克服设计难题，并找到进一步优化设计和开发的机会，并最终帮助减少Glasshouse封闭式抛物槽安装的高投资成本。
