Improving Condensate Quality – Water Technology Report

Mar 13, 2017 · Historically, steam condensate has been viewed as the best quality water in the energy center. Pure condensed steam has all the characteristics of distilled water, i.e. low concentrations of dissolved and suspended solids as reflected in very low specific conductance and filterable residue. By comparison, raw boiler makeup contains hardness, alkalinity, …

Controlling TDS in the Boiler Water | Spirax Sarco

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.

Industrial Water Analysis - Lenntech

Boiler Water. The boiler water itself must be dosed in order for the boiler to run efficiently and safely. A chemical imbalance can lead to corrosion and damage to the system and this damage can ultimately lead to boiler failure and injury. Boiler water analyses are basically aimed at keeping the parameters within established limits. Tests include

Removing the water from the system is the best way to prevent off-line corrosion. This accomplished by draining the water from the boiler while it is still hot and under 25 – 50 psi of system pressure. This is done so that the residual heat can dry the internal surfaces and ensure that all "dead legs" are drained.
