【Abstract】 Based on the “three-link-model” of the pulp and paper mill′s energy system, the way of improving energy efficiency is pointed out for the mill. Some energy saving measures are brought forward according to the process and equipments operation in the mill. From comparison of energy efficiency after and before improving energy system, recovery efficiency of energy and exergy have increased 20.4% and 10.4% respectively. Therefore, the improving efficiency measures and the model are viable and reliable.更多还原
