| Abstract: |
| 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. |
