| 摘 要： | 能量的传递和转换必然伴随其"质"--(火用)的传递和转换.能量在传递和转换过程中其量守恒,而炯在传递和转换过程中其量不守恒,因此(火用)必有其独特的传递和转换规律.常规(火用)平衡分析综合热力学第一定律和第二定律,以(火用)效率为评价指标,属于静态热力学研究.参照工程(火用)传递评价准则,提出了堋传递系数、(火用)流密度、(火用)损率等评价指标,并针对某台锅炉机组进行了(火用)传递分析,通过与常规的传热及(火用)平衡分析比较,提供了一些新的技术评价信息.

| Abstract: | Energy transfer and conversion are inevitably accompanied with exergy transfer and conversion.Energy is conservative in its transfer and conversion process,while exergy is known to be non-conservative due to the irreversibility of its transfer process.The exergy analysis based on the thermodynamics first law and second law.exergy efficiency is used as the evaluation index.It is one method of the sedentary thermal research.Incorporating the evaluating criterions of engineering exergy transfer and the definit... |
