以软化水或除盐水为补给水的工业锅炉,在工作状态下即使补给水水质稳定,由于锅水浓缩倍率、补水量及蒸汽回用量、压力、温度、投加药剂的成分和用量、锅水pH值等因素发生变化,锅水溶解固形物RG及各种离子浓度的比例随之改变,影响RG与电导率k的线性关系。某一水样固导比的测定结果不能适用于各种运行工况下的不同成分和浓度的锅水,根据情况仍要借助重量法对固导比进行定期校正,步骤繁
The industrial boilers with demineralized water or demineralized water as the replenishment water, even if the quality of the make-up water is stable under the working condition, the pot water concentration ratio, the replenishment amount and the steam return amount, the pressure and the temperature, pH and other factors change, pot dissolving solid content of RG and a variety of ion concentration ratio changes, affecting RG and conductivity k linear relationship. The determination result of a certain water solidification ratio can not be applied to different compositions and concentrations of pot water under various operating conditions. According to the situation, the solidification ratio should still be corrected periodically by gravimetric method.
