连续蒸煮与黑液预提取热量平衡分析与节能技术探讨

Studies on heat balance analysis and energy saving technology of continuous cooking and pre-extraction of black liquor

连续蒸煮与间歇蒸煮相比其用汽方式不尽相同,热量流向有较大差别,连续蒸煮的节能潜力大但没有现成的应用经验,节能方式需要探索。本文介绍采用连续蒸煮加黑液预提取相结合的新工艺,通过热量平衡分析研究其优势和特点,提出可进一步改善连续蒸煮节能的技术方案。

The continuous cooking has different steam-using way to the batch cooking with the different heat flow direction. The potential of energy saving of continuous coooking is very big, but it does not have any ready-made application experience, the method of saving energy needs exploring. This article introduced the new technique of combining continuous cooking with pre-extraction of black liquor. Technical program of saving energy of further improving continuous cooking was put forward by analyzing its advantage and characteristics through heat balance.
