| 摘 要： | 太阳能和常规的燃煤电厂耦合,可以提高燃煤电厂的效率,减少化石燃料的使用,达到保护环境的效果;同时,可以弥补太阳能热发电的不足。通过对太阳能集热场替换回热抽汽的分析,得到其对原燃煤机组效率、汽耗率等的影响;并探讨了太阳能与燃煤耦合发电的不同集成方式对于燃煤机组的影响。研究结果表明：太阳能集热场与H1高压加热器并联为最佳方案,对原燃煤机组增益最大,效率由原来的42.90%提高为44.78%,提高了1.88%;标准煤耗率由原机组的0.286 7 t/h降低为0.274 6 t/h,降低了0.012 1 kg/k Wh。

| Abstract: | Solar and conventional coal-fired power plant scoupling can improve the efficiency of coal fired power plant,reduce fossil fuel use and protect environment; at the same time,it can make up for the shortage of solar thermal power generation. Based on the solar collector field replacement of regenerative steam,the effect on the original coal-fired unit efficiency and steam consumption rate are discussed as well as the influence of different integrated solar energy and coal-fired power generation on coal-fired units. The result shows that solar thermal field and H1 highpressure heater in parallel is the best solution,the original coal-fired units gain maximum,efficiency increased by1. 88% from 42. 9% to 44. 78%,Standard coal consumption rate reduced by 0. 012 1 from 0. 282 3 t / h to 0. 270 4 t / h. |
