Water Impurities in Boiler Water Treatment

٤ .resategypt.com Boiler Ratings and Boiler Load • The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. • Large boiler capacity is generally given in lbs of steam evaporated per

The conductivity of the boiler water is measured with the conductivity transmitter (QICA+) and converted to a standard electrical signal (4 – 20mA). This signal is processed in the Boiler Control BCO, the measured conductivity displayed in the control cabinet and the actuating signal to open the motorised surface blowdown valve is generated.

Inferred pH in Steam Plant Water Chemistry Monitoring

As with boiler water TDS measurement, conductivity (μS/cm) x 0.7 = TDS in parts per million (at 25°C). Note: the sample of feedwater that is required is from the boiler feedline or from the feedtank and is not a sample of the make-up water supplying the feedtank. The quantity of steam which the boiler generates, usually measured in kg/h.
