【摘要】 改进纯碱生产工艺,采用多股流扁管换热器将120℃左右的炉气与空气进行换热并将空气加热到90℃左右,再将加热后的空气预热重碱,从而减少重碱的湿含量。对比以前采用冷却水冷凝冷却炉气,年节省标煤6567.92 T。更多还原

【Abstract】 To change the soda ash production process,the air will be heated to about 90 ℃ in a multiple flow flat tube heat exchanger by the air and the furnace gas around 120 ℃ heat exchange.Then the heated air is used to preheat the heavy alkali to reduce the moisture content.Compared to the furnace gas condensation and cool using cooling water,6567.92 tons standard coal can be saved annually.更多还原
