摘要
通过分析纸机干燥部的能耗,初步探索了干燥部能源效率在线监测与评价方法,提出了干燥部能源效率在线监测的4类指标,即干燥部蒸汽单耗、干燥部热效率、通风与余热回收子系统电单耗、通风与余热回收子系统热回收效率,并建立了各个指标的计算模型;基于提出的指标对干燥部能源效率的评价方法进行了进一步拓展研究,提出的干燥部能源效率在线评价方法可从能效对标和能效等级2个维度实时评价干燥部能效水平。
Through the analysis of the energy consumption in dryer section of paper machine,the online monitoring and evaluation method of energy efficiency in dryer section was preliminarily explored.Four energy efficiency indexes for online monitoring in dryer section were put forward,which were specific steam consumption and heat efficiency of dryer section,specific power consumption of ventilation and heat recovery system,heat recovery efficiency of ventilation and heat recovery system,their calculation models were established simultaneously.Finally,based on the proposed indicators,current paper authors studied the energy efficiency evaluation method of dryer section.Therefore,the energy efficiency level of the dryer section could be evaluated in real time from two dimensions of energy efficiency benchmarking and energy efficiency rating.
