摘要
由于太阳能供给的间歇性,单独投资建造的太阳能热发电系统经常会出现设备成本高、利用率低、收益低等问题。因此,利用太阳能热发电系统与常规燃煤发电系统都有汽轮机部分这一特点,将槽式抛物太阳能集热器集成到常规燃煤发电系统中,寻求改造现有燃煤发电系统的新途径。以某300 MW机组为例,利用弗留格尔公式进行变工况计算,然后进行热经济性分析,为太阳能辅助燃煤热发电混合系统的建立提供理论参考。
Due to the intermittency of solar energy supply, projects based solely on the solar thermal power generation system can be very expensive with low availability and low return of income. Taken that both the solar thermal power generation system and the conventional coal-fired steam have the turbine generating system, the solar thermal energy, could be integrated into the conventional coal-fired power generation system. This new way of improving the existing coal-fired power generation system is researched in this paper. Taking a 300 MW generating unit as an example, variation calculations are conducted using Friuli Eagle formula, and then thermal economical benefits are analyzed to provide theoretic data for building the solar supported coal-fired power generation system.
