摘要

针对可再生能源快速发展造成的电网不稳定的问题

提出一种基于三罐熔盐储热系统的燃煤调峰机组

研究高温罐中熔盐温度和释热过程熔盐质量流量对机组调峰性能的影响。结果表明：高温罐中熔盐温度的升高可延长储热时间

增加释热过程机组发电功率和㶲效率

但会降低储热过程㶲效率。释热过程熔盐质量流量的增加使发电增量减小。对于完整的调峰过程

高温罐中熔盐温度越低、释热过程熔盐质量流量越小

燃煤机组的综合调峰性能越好。

Abstract

Taking a 600 MW subcritical coal-fired unit as the research object

a new three-tank molten salt thermal energy storage system is proposed

and the effects of molten salt temperature （） in the hot tank and molten salt mass flow （） during discharging on the peak shaving performance of the coal-fired unit are studied. The results show that the increase of can prolong the charging time and increase the generating power of the unit during the discharging process

but it will reduce the exergy efficiency during charging. With an increase in

the increment of power generation in the discharging process decreases. For the complete peak-shaving process

the lower the and the smaller the

the better the comprehensive peak-shaving performance of coal-fired units.
