pH-phosphate Co-ordinated Graph

During one of the studies of boiler pH vs phosphate concentration I found that the problem of data plotting takes lot of time manually & chances of error are also there. For a clear picture of the system co-ordinated pH-phosphate diagram is must.

Therefore I developed the Excel sheet for the same. In our case we were having 3 boilers B-601, B-605 & B-606. From a standard curve I derived the correlation & put the data in Excel sheet called "Data". Now you can put your pH against phosphate concentration in the corresponding cell. For example say for B-605 you need to put pH on F column as 9.70 against phosphate value of 3.56 in row no 260.

This diagram is useful in identifying the effectiveness of your boiler pH control program. After getting this curve you can have an analysis of Caustic gauging zone, Or Acidic Zone or localized attack / proper system.

Using this sheet we maintained very well pH control system.

So Use this file & improve your boilers health.
