地热-太阳能联合有机朗肯循环发电技术研究

Solar-Geothermal Hybrid Cycleof Organic Rankine Cycle(ORC) Analysis in Power Generation

介于我国地热能和太阳能之间存在多种潜在协同关系,提出了一种地热-太阳能联合发电技术,该技术可以利用太阳能提高地热资源的焓值,实现一种既经济又能够发挥地热和太阳能潜在能量的方法。首先对预先加热方案、过热方案和太阳能-闪蒸-双工质方案进行了研究,并给出了各自的系统示意图;然后对地热-太阳能联合发电系统的性能进行了预测,并对联合发电系统的成本进行了分析,评估了该系统对环境的影响。

Since there are several potential synergetic relationships between geothermal energy and solar ener-gy,Solar-Geothermal Hybrid Cycle had been proposed. It makes use of solar energy to enhance the enthalpy of geothermal resources,and it is also a economical way to achieve a potential energy realization of Geothermal energy and solar energy. Firstly, the pre-heating, superheating schemes and “solar-flash-binary” model have been investigated,and their respective systems have also been presented. Secondly, the characteristics of the performance in Solar-Geothermal Hybrid Cycle have been predicted,and then the cost of the combined system have been given to assess the impact of the system on the environment.
