| 摘 要： | 阐述热分析和(火用)分析在氧化铝蒸发工序节能降耗中的意义,建立工序的热分析和(火用)分析模型,并以此对某厂蒸发工序进行热效率和(火用)效率的分析.研究结果表明:蒸发工序热效率仅为30.67％,(火用)效率仅为15.08％,热损失严重,用能水平低,节能潜力大；热分析确定的高耗能环节为冷凝水自蒸发器和末效蒸发器,(火用)分析确定的高耗能环节不仅为冷凝水自蒸发器和末效蒸发器,还有传热过程(火用)损失和流动过程(火用)损失.通过对蒸发工序进行热分析和(火用)分析,评价工序用能水平,确定耗能的主要环节、部位及节能潜力,指出蒸发工序的节能降耗途径. |
| 关 键 词： | 氧化铝 蒸发工序 热分析 (火用)分析 节能降耗 |
