对中国木浆和麦草浆碱回收能耗自给的分析

分析了我国木浆与麦草浆碱回收的主要区别，以我国木浆、麦草浆典型碱回收为实例，对蒸发、燃烧、苛化系统的能耗进行了计算。得出麦草浆碱回收生产热能的63．55％能够满足碱回收的全部用能需求，扣除碱回收自用能量外，还可以满足制浆所需热能的62．02％，满足所需全部能量的51．95％。国内木浆碱回收生产能量的52．51％能够满足包括白泥回收在内的碱回收的全部用能需求，扣除碱回收自用能量外，还可以满足木浆制浆所需的全部能量，并且还有相当于自产热能的16．93％外送，超过欧洲造纸发达国家上个世纪末的水平。

The analysis on energy self-sufficiency in alkali recovery of wood pulp and wheat straw pulp in China

The difference between the alkali recovery for wood pulp and wheat straw pulp in China was analyzed in this paper.The energy consumption of evaporation,burning and causticizing systems were calculated according to the typical alkali recovery systems for wood and wheat straw pulp in China.The results show that 63.55% of the whole heat energy produced in a alkali recovery system for wheat straw pulp can satisfy the whole energy demand inside the system.The remainder heat energy can satisfy 62.02% of the whole energy demand required in its pulping plant or satisfy 51.95% of the overall energy demand.For the wood pulp alkali recovery systems in China,52.51% energy produced in alkali recovery can satisfy the whole energy demand inside the system including lime mud recovery.Deducting the energy consumption in alkali recovery system,the remainder heat energy can satisfy the whole heat energy demand required in pulping,and also 16.93% of whole heat energy can be delivered outside,which exceeds the level of developed countries in Europe in the late period of the last century.
