method for determination of mercury in boiler flue gas


Water Hardness - an overview | ScienceDirect Topics

Water hardness is handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.

In this method an excess of soluble phosphate is added to boiler water. It react with Ca and Mg salts and form soft sludge of Ca and Mg phosphate which can be removed by blow down process 3MCl2 + 2Na3PO4 → M3(PO4)2↓ + 6NaCl The three sodium orthophosphates viz., Na3PO4, Na2HPO4 and NaH2PO4 have been used for phosphate conditioning.

This method can produce results in 1 day, and preliminary evidence indicates that its sensitivity and specificity are comparable to those of cell culture, which can take 10-14 days to obtain results. Further testing may lead to acceptance of this technique as the method of choice for monitoring water sources for contamination.

Fly ash - Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
