这项研究的目的是评估伊朗工业部门使用能源的质量。沿着能量分析，进行了火用分析，以便更深入、更现实地了解该部门的状况。从17个不同行业的初级能源利用已被认为是每个行业的火用和能源效率的计算，后来为伊朗的工业部门。在所有行业和工业部门中，火用效率远低于能源效率。结果表明，从火用分析的结果的基础上，效率提高的优先事项是不同的能量分析，这反过来又表明，火用分析作为一个适当的工具，为决策者。能源退化的来源和机制，导致能源质量的退化已经确定。此外，提出了更好地利用能源质量的补救措施。伊朗整个工业部门的能量和火用效率分别约为63%和42%。石油、钢铁、塑料和水泥工业在工业部门总投入能源的质量破坏中所占比例最高。铝工业的火用效率最高，为52.5%。平均熵温度也被提出作为一种工具，用于了解每个行业所需的能源质量的程度，从而更好的质量匹配，从而导致更好的能源质量利用。
The purpose of this study is to assess the use of quality of energy in Iran’s industrial sector. The exergy analysis has been performed along with energy analysis, in order to gain deeper and more realistic understanding of the sector’s condition. Primary energy utilization from seventeen different industries has been considered for calculation of the exergy and energy efficiencies for each industry, and later for Iran’s industrial sector. The exergy efficiency is much lower than energy efficiency in all industries and also in the industrial sector. It is shown that based on the results from exergy analysis the priorities for efficiency improvement are different from that of energy analysis; this in turn suggests that exergy analysis as a proper tool for policy makers. The sources of energy degradation and the mechanisms which cause degradation of quality of energy have been identified. Moreover remedial actions for better utilization of quality of energy are proposed. The energy and exergy efficiencies for the entire industrial sector of Iran were approximated as 63% and 42%, respectively. The oil, iron and steel, plastic and cement industries are found to have the highest share in destruction of quality of total input energy to the industrial sector. The aluminum industry has the highest exergy efficiency of 52.5%. Mean entropic temperature is also proposed as a tool for understanding the degree of quality of energy required in each industry and consequently better quality matching which leads to better energy quality utilization.
