Conductivity Measurements for Boiler Blowdown | Yokogawa ...

Manual blowdown control cannot maintain this level of control more than 20% of the time. Upgrading from manual blowdown control to automatic control can reduce a boilers energy use by 2 5 percent and blowdown water losses by up to 20 percent. Feed water usually contains one limiting component such as chloride sulfate carbonate or silica.
