| 摘 要： | 在系统梳理燃料分析理论的基础上,结合氢气物性和利用趋势及其独特之处,对氢气的燃料进行了分析探讨.并将氢气的燃料与其他理想气体进行了比较,提出如果氢气用于发电,其能源利用过程中,热力学第二定律效率必须高于天然气6.7%才能被视为科学的利用,这将对氢气的合理利用提出挑战.在分析和计算基础上得出氢气的燃料大于其低位热值,小于...

| Abstract: | Based on the systematical analysis of fuel exergy,the fuel exergy of hydrogen is analyzed and discussed in this article,combining with the physical properties and the utilization trends.Through the comparison of the fuel exergy of hydrogen and other ideal gases,if the hydrogen is used for power generation,it will be scientific utilization only when the efficiency of the second law of thermodynamics exceeds 6.7(the efficiency of natural gas) in the energy utilization,which will challenge the reasonable utilization of hydrogen.The result of analysis and computation indicates that the fuel exergy of hydrogen exceeded the lower heat value(LHV),and was less than the higher heat value(HHV). |
