| 摘 要： | 本研究搭建了太阳能热化学实验平台,依托室内太阳模拟平台,进行了2 kW太阳能甲烷重整反应器的实验研究,探究了反应温度、反应物流量等关键参数对系统性能(甲烷转化率、产物选择性)的影响,并基于燃气-蒸汽联合循环发电系统模型,模拟计算了太阳能热化学互补发电系统性能。结果表明,当反应器腔体的平均温度为880℃、甲烷流量为5.5 L·min^-1、水碳比为3:1时,甲烷的转化率为55.8%,太阳能净发电效率可达26.0%。

| Abstract: | In this paper,a solar thermochemical experimental platform was built,and experimental research on a 2 kW solar methane reforming reactor was conducted with an indoor solar simulator.The effects of key operating parameters such as reaction temperature and reactant flow rate on system performance(methane conversion rate and products selectivity)were investigated.Then a gas-steam combined cycle power plant model was built to investigate the solar-to-electricity efficiency under different operating conditions.At an average reactor cavity temperature of 880℃,with methane flow rate of 5.5 L·min^-1 and water-to-methane ratio of 3:1,methane conversion rate was 55.8%,and the net solar-to-electricity efficiency reached 26.0%. |
