At the high temperatures water with Ph value 7 will act as
an acid. So that we will always maintain the Ph valve in
Higher side based on the type of water used and the

CONTAIN SOME SALT FORMING CHEMICALS. BY MAINTAINING HIGH PH
IT WILL CONVERT THAT SALTS INTO SOME SLAGS THIS WILL BE
REMOVED THROUGH CENTRAL BLOW DOWN LINE IN THE DRUM.

Answer / surya

Alkalinity measures the ability of a solution to neutralize acids to the equivalence point of carbonate or bicarbonate. This is the main reason we are maintaining PH at higher side rather than near the margin (<7 is acid). so that it provide optimum corrosion control and also provides sufficient alkalinity to avoid the precipitation of any residual scale forming compounds.

Answer / ganesh r.k

Water with 7.0 ph is acidic in nature. this will in
increase the corrossion tendency in boiler shell so we have
to keep the ph value between 8 to 9
