摘　　要：为使锅炉水中PO_4^(3-)和SO_3^(2-)离子含量符合GB 1576—2001《工业锅炉水质》中规定的要求,达到有效减少水垢,确保锅炉安全运行的目的。为此,采取下列措施:调配阻垢剂;选取阻垢剂注入点;选取阻垢剂注入方法;确定阻垢剂注入量;设计阻垢剂注入定量控制线路;阻垢剂注入设备的选型、安装和调试。改进后效果使锅炉水中PO_4^(3-)和SO_3^(2-)离子含量达到15~20mg/L;排污率为7.5~8.5%。因此,采用定量控制方法能有效控制卷烟工业锅炉水中的PO_4^(3-)和SO_3^(2-)离子含量。To meet the standard on PO4^3- and SO3^2- ions content in the boiler water and reach the requirements in the GB1576--2001 industrial boiler water quality, to effectively reduce the scale and ensure the boiler safe operation, the paper takes the following measures about preparing inhibitors, selecting the injection point of the scale inhibitor and the injection method of the scale inhibitor, determining the amount of scale inhibitor injection, designing the quantitative control circuit of scale inhibitor into, the selection, installation and debugging of the scale injection equipment. The improved results of PO4^3- and SO3^2- ions content in the boiler water reaches 15 -20mg / L and the emission rate is 7. 5% -8. 5%. Thus, quantitative method can effectively control the PO4^3- and SO3^2- ions content in tobacco industrial boiler water.
