Boiler Drum Level - CR4 Discussion Thread
Dec 05, 2012 · Your pH within the boiler drum should be gradually built up to 10.0 - 11.5. I suppose this has been done. The other interesting issue is the discussion of blowing down/flushing the transmitters. You should be having a HP and LP impulse piping from your Steam Drum coming down to connect with the Drum level transmitter.

Inexplicable pH drop in boiler blowdown water
Jan 27, 2013 · March 17, 2012. Q. I am working in a power industry of 500 MW unit and the drum pressure is around 190 Kg/cm2. I am facing the problem i.e., the drum pH is gradually in decreasing tendency i.e., around 4.4 and the phosphate reserve is < 1.0 and the pH and conductivity of the feed, condensate and steam values are in normal range i.e., pH - 8.9 and conductivity is 4.5 to 5.0.

silica in boiler water - Constructed items general
Sep 24, 2003 · We monitor silica at the inlet of the anion resin and at the outlet. Typical values are 200ppb on the inlet and 0.0ppb on the outlet. What is confusing me is that following a minor plant outage the readings on the inlet now exceed 1200ppb and the life span of the anion resin has been reduced as a result. The silica concentration at the anion
