太阳能光热发电技术综述

Introduction on CSP Technologies for Power Production

从经济、环境和社会角度来看,目前的能源供应和使用趋势明显不是可持续的。太阳能聚光光热发电(CSP)技术给拥有充足光照资源的地区带来了希望。太阳能聚光光热发电(CSP)技术可为法向直接日射辐照度(DNI)强的地区提供低碳、可再生能源。该文在简要分析太阳能光热发电技术现状基础上,介绍了太阳能光热发电当前的主要技术以及如何提高太阳能热发电实用性的相关技术。通过使用储热系统、后备燃料或带燃料的混合动力发电可以提高太阳能热发电的实用性。

Current trends in energy supply and use are unsustainable from the perspective of economics, environment and society economically, environmentally and socially. The emerging technology known as concentrating solar power （CSP） brings hope to holds much promise for countries with plenty of sunshine. Concentrating solar power （CSP） can provide low-carbon and renewable energy resources in countries or regions with strong direct normal irradiance （DNI）. On the basis of a brief introduction of CSP status, this paper introduces the current CSP technologies for power production. In addition to that, thermal storage and backup or hybridization with fuels can enhance the value of CSP capacities.
