【摘要】 介绍了热电厂炉水处理中存在的 pH合格率低、水冷壁沉积率高的问题 ,改进了处理方法 ,由协调磷酸盐处理改为低磷处理 (pH9.4～ 9.6,PO43 - 2～ 3mg/L) ,经过一年的实际应用 ,低磷处理取得成功 ,水汽品质提高 ,沉积率下降 ,腐蚀得到抑制 ,并有较好的经济效益。更多还原

【Abstract】 The artical introduces the problems in boiler water treatment in steam power plants. The problems are that pH eligibility is low and that scaling rate of water wall tube is high. they are improving the boiler water treatment,changing from phosphate treatment to low phosphate treatment (pH9.4～9.6,PO 3- 42～3 mg/L).After one year application,the new treatment method has had success. The water and steam quality eligibility gets higher,scaling rate of water wall tube gets lower. The corrosion of water wall tube gets inhibited and gets better economic benefit.更多还原
