硝酸盐类熔盐在太阳能光热发电中的应用

Application of molten nitrate salt on solar thermal power generation

太阳能热发电技术(CSP)是光热资源高温利用的一种,其热存储技术,可将太阳能集热后通过换热装置加热水产生蒸汽,然后驱动传统的汽轮发电机产生电能,实现'光-热-电'的转化.文中对比了几种太阳能热发电技术工作原理和现状.重点对太阳能熔盐的标准规范的制定,太阳能熔盐产品的市场前景进行了论述.随着太阳能光热发电技术在我国新兴能源领域的崛起,广阔的太阳能熔盐市场为硝酸、硝酸盐企业在未来的几年内的发展迎来良好的机遇.

Concentrating Solar Power(CSP)is one way to make use of light and heat resources.The heat storage technology can heat water to generate steam by heat exchangers after solar energy is collected,and then drive the traditional turbine generator to generate electric energy,realizing the conversion of“light-heat-electricity”.In this paper,several CSP technologies are contrasted in the aspects of working principle and situation.Establishment of standards on solar molten salt and market prospect of molten salt products are also illustrated.With the rise of CSP technologies in China's emerging energy field,the vast solar molten salt market will provide a good opportunity fordevelopment of nitric acid and nitrate enterprises in the next few years.
