太阳能热化学制氢反应腔的热性能分析

Thermal Performance Analysis of Cavity for Solar Thermo-Chemical Hydrogen Production

本文修正了反应腔吸热效率的计算公式,在已有碟式聚光器的基础上,设计了一个太阳能热化学制氢反应器。本文计算了各种热损失对吸热器吸热效率的影响,也计算了反应腔倾斜角度以及采光孔尺寸对吸热效率的影响。计算结果表明,反应腔倾斜角度对反应腔热效率影响不大;采光孔直径越大,吸热效率越低。

This paper modified the formulation of absorption efficiency and designed a reactor which based on a solar energy concentrator.The paper calculated diversified heat losses effect on the entire thermal efficiency based on a solar hydrogen production cavity.Also we calculate the absorption coefficiency and the inclination of reactor on thermal efficiency.The results showed that inclination angle of cavity and heat absorption coefficient had no influence on the thermal efficiency.The larger radius of aperture,the lower thermal efficiency.
