Abstract: For reclaiming the secondary steam from the open steam condensate reclaiming system in tobacco processing facility and reducing heat and steam condensate loss, the steam condensate reclaiming system was improved. Using soft water from sodium ion exchanger as a cooling medium, it cooled down secondary steam by means of a heat exchanger, the secondary steam condensed and flowed back to a collection container. The results of application showed that after improvement, 900 kg of secondary steam produced by a 1.2×10⁶ kg threshing and redrying line every day was reclaimed completely, 37000 kg of coal and 225000 kg of soft water were saved per year, which saved 38030 RMB yuan in total.
