针叶木、阔叶木混合蒸煮以及连续蒸煮系统的选型

Mixed cooking and the selection of continuous cooking systems for softwood and hardwood

通过阔叶木不同树种间的混合蒸煮生产实践和针叶木、阔叶木混合蒸煮试验,表明在一定比例下,针叶木、阔叶木混合蒸煮是可行的。混合连续蒸煮系统型式的选择,需满足预浸渍效果好、纤维素与木聚糖得率高、对木片质量波动的敏感性低、渣量低、操作平稳性优异、木片喂料系统的操作可靠性高和设备维护量低等要求。

In the face of production practice of mixed cooking of different kind of hardwood, a mixed cooking experiment of softwood and hardwood was made. The experiment show that the mixed cooking of softwood and hardwood is feasible under definite ratio. The selection of continuous cooking system must meet these requires： ideal impregnation, high cellulose yield, high xylan yield, low sensitivity for the variety wood materials, low reject, high running placidity, high availability of wood feeding and low maintenance of equipment.
