We are operating four boilers at 105 Kg/Cm2 pressure. Silica in their steam drums is as low as 120 ppb. CBD, IBD and sample coolers valves from their drums are also closed. Moisture in flue gases are also analyzed showing no tube leakages. we fail to understand why silica is so less? BFW being fed to boilers is less than 10 ppb silica and Dissolved Oxygen less than 10 ppb. Eliminox is being dosed as oxygen scavenger. please advise what to check further as we fear that there is some thing going wrong that can led to any failure.
