Controlling TDS in the Boiler Water

An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.

Water conductivity

Water conductivity definition. Definition and description. Conductivity of a substance is defined as 'the ability or power to conduct or transmit heat, electricity, or sound'.Its units are Siemens per meter [S/m] in SI and millimhos per centimeter [mmho/cm] in U.S. customary units.
