In Mitsubishi Paper Mills, Ltd. Hachinohe mill, we have continued various activities for energy saving. We introduce a summary of these past 5 years.
And as one example of them, 51, 52 supercalenders, we remodeled the warm water facilities into the purpose by steam-saving and warm water displacement reduction in June, 2008. Because introduced original warm water collection⁄reuse flow facilities, but, as for collected warm water from two supercalenders in parallel, and reusing it, there were many problems on the real operation ; a warm water flow as much as possible simple ; became it, and was able to tie it to the improvement of the steam-saving, reduction of the displacement and operation characteristics. We introduce steam by this warm water facilities flow remodeling-saving and displacement reduction by this report.
