With chloride method of saturated steam condensation water and chlorine root Cl - pan of water ratio of the percentage of saturated steam humidity, its computation, such as: saturated steam humidity chlorine root omega = saturated steam condensation water chlorine root (mg/kg) pan of water (mg/kg) x 100% (1) the pan of water conductivity and steam condensation water conductivity measurement steps are the same, when measuring water conductivity should be pay attention to the following:
用氯根法测得1吨燃气锅炉饱和蒸汽冷凝水和锅水氯根Cl-含量之比的百分数为饱和蒸汽湿度,其计算如式: 饱和蒸汽湿度ω= 饱和蒸汽冷凝水氯根含量(mg/kg) 锅水氯根含量(mg/kg)×100%(1) 锅水电导率与蒸汽冷凝水电导率的测量步骤相同,在测量锅水电导率时需注意以下几点:
(1) when the water is cloudy, the filter should be filtered. When the concentration of the chloride ion is high, it is diluted and measured.
(1)如锅水比较浑浊时,需用滤纸进行过滤;锅水氯离子浓度高时稀释后测定。
(2) when the concentration of chloride ions in the steam condensate is low, the sampling quantity of one or more times is measured.
(2)蒸汽冷凝水中氯离子浓度较低时,增加一倍或多倍的取样量,进行测定。
With conductivity meter respectively measured the percentage of steam condensed water and the ratio of boiler water conductivity of saturated steam humidity, its computation, such as: saturated steam humidity omega = saturated steam condensation water conductivity (mu s/cm) pan of water conductivity (mu s/cm) x 100% (2) when measuring need to pay attention to the following:
用电导率仪分别测得蒸汽冷凝水和锅水电导率之比的百分数为饱和蒸汽湿度,其计算如式: 饱和蒸汽湿度ω= 饱和蒸汽冷凝水电导率(μs/cm) 锅水电导率(μs/cm) ×100% (2) 在测量时需要注意以下几点:
(1) the solution conductivity is associated with temperature, so the steam condensed water and boiler water shall be measured after cooling to the same temperature, such as temperature is different, use with temperature compensation measure conductivity apparatus;
(1)由于溶液电导率与温度有关,因此蒸汽冷凝水和锅水应冷却到同一温度后进行测量,如温度不同,则需使用带温度补偿的电导率仪进行测量;
(2) when measuring steam condensation water and boiler water conductivity by an electric conductivity instrument, the electrode should be cleaned in time to prevent cross contamination.

(2)如用一台电导率仪分别测量蒸汽冷凝水和 锅水电导率时,需对电极及时进行清洗,防止交叉污染。
