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:
用氯根法測得1噸燃氣鍋爐飽和蒸汽冷凝水和鍋水氯根Cl-含量之比的百分數(shù)為飽和蒸汽濕度,其計算如式: 飽和蒸汽濕度ω= 飽和蒸汽冷凝水氯根含量(mg/kg) 鍋水氯根含量(mg/kg)×100%(1) 鍋水電導(dǎo)率與蒸汽冷凝水電導(dǎo)率的測量步驟相同,在測量鍋水電導(dǎo)率時需注意以下幾點:
(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)如鍋水比較渾濁時,需用濾紙進行過濾;鍋水氯離子濃度高時稀釋后測定。
(2) when the concentration of chloride ions in the steam condensate is low, the sampling quantity of one or more times is measured.
(2)蒸汽冷凝水中氯離子濃度較低時,增加一倍或多倍的取樣量,進行測定。
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:
用電導(dǎo)率儀分別測得蒸汽冷凝水和鍋水電導(dǎo)率之比的百分數(shù)為飽和蒸汽濕度,其計算如式: 飽和蒸汽濕度ω= 飽和蒸汽冷凝水電導(dǎo)率(μs/cm) 鍋水電導(dǎo)率(μs/cm) ×100% (2) 在測量時需要注意以下幾點:
(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)由于溶液電導(dǎo)率與溫度有關(guān),因此蒸汽冷凝水和鍋水應(yīng)冷卻到同一溫度后進行測量,如溫度不同,則需使用帶溫度補償?shù)碾妼?dǎo)率儀進行測量;
(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)如用一臺電導(dǎo)率儀分別測量蒸汽冷凝水和 鍋水電導(dǎo)率時,需對電極及時進行清洗,防止交叉污染。
