摘　　要：红河制糖有限公司130 t/h锅炉炉水原采用磷酸盐处理,此方法存在pH值波动大,锅炉排污次数多,排污量大,锅炉相关管路积垢多,传热效率低,蒸汽带盐多对汽轮机叶片损伤大等问题。2022/23年榨季将炉水处理改进为Mix-A小分子胺与磷酸盐协调控制后,实际运行结果表明:炉水pH值控制达标且稳定、锅炉排污率降低,同时小分子胺能够剥离和分散水冷壁管表面垢层,降低管壁沉积物的生成量,提高炉管换热效率,达到节能减排的效果,还能降低蒸汽带盐多对汽轮机叶片的损伤。本方案的成功实施可为甘蔗制糖企业中压锅炉炉水处理提供一个新的方法与思路。The 130 t/h boiler water of Honghe Sugar Co.Ltd.was originally treated with phosphate.This method had problems such as large pH fluctuations,frequent boiler discharge,large discharge volume,excessive scaling in boiler related pipelines,low heat transfer efficiency,and significant damage to turbine blades caused by excessive salt content in steam.In the 2022/23 crushing season,the treatment of boiler water was improved by coordinating the control of Mix-A small molecule amine and phosphate.The actual operating results showed that the pH value of the boiler water was controlled to meet the standard and stable,and the boiler discharge rate was reduced.At the same time,small molecule amine can peel off and disperse the scale layer on the surface of the water-cooled wall tube,reduce the amount of sediment on the tube wall,improve the heat transfer efficiency of the furnace tube,achieve energy-saving and emission reduction effects,and also reduce the damage of steam salt to the turbine blades.The successful implementation of this plan provides a new method and approach for the treatment of medium pressure boiler water in sugar cane enterprises.
