Discussion on Establishing and Industrial Application of Three-Link Model of Energy System for a Pulp and Paper Mill

Based on the analysis of process energy system optimization techniques and energy system models,the energy system of a pulp and paper mill is classified as three sub systems (three links):energy conversion link,energy use link and energy recovery link in this paper.The three link model(including the physical model and the mathematical model) for a pulp and paper mill energy system is established,which will provide the scientific basis for the optimization of energy system of papermaking enterprises.In this paper,the energy system analysis for a pulp and paper mill are completed based on the three link model,and the energy efficiency of the three link of process energy system is given respectively according to the analysis results.Some factors that cause low energy efficiency and high energy loss are discussed and analyzed.And this paper points out that the pulp and paper mill has enormous energy savings potential.
