Physical and chemical methods of organic impurities control in the feed water of waste heat boilers of thermal power plants
For the quantitative control of the organic impurities content in deeply purified waters, a simple, effective and inexpensive method with the carbon tetrachloride extraction was developed for waste heat boilers feeding. The presented methodology served to study the organic substances content in the...

| description | For the quantitative control of the organic impurities content in deeply purified waters, a simple, effective and inexpensive method with the carbon tetrachloride extraction was developed for waste heat boilers feeding. The presented methodology served to study the organic substances content in the nutrient water of the Kazan CHP-1 and Kazan CHP-3 waste heat boilers. According to the results of various physical and chemical methods, the samples extracted from feedwaters of waste-heat boilers have been were examined for their qualitative composition. The discovered organic substances belonged predominantly to the class of humic substances, which, due to their physicochemical properties, can penetrate into all types of deeply treated water. The proposed method for complex determination of organic impurities by extraction in the feedwaters of a waste-heat boiler may be used as an alternative to the total organic carbon analysis. |
