| Abstract: |
| Energy consumption reduction is becoming focus in papermaking industry. To further reduce energy consumption and increase energy efficiency of paper machine dryer section, the synergic control for energy consumption was put forward. The energy consumptions of steam condensate thermal system and hood ventilation thermal system were considered together to recycle the secondary thermal energy. A DCS control system for energy consumption of high strength fluting paper machine was designed. This system integrated above-mentioned systems, not only reduced the energy consumption of paper machine dryer section but also laid a foundation for achieving overall optimization of dryer section. This control system has been used in many high strength fluting paper machines and had a better energy-saving effect. To achieve overall optimization of dryer section, the data-driven optimization control framework was designed. The large amount of operation data was used to update the model and established the optimal control strategy database. Thus the optimization control strategy which matched current process conditions best could be found quickly, and energy consumption reduction was realized. |
