The Effects of High Conductivity in Boiler Water

2019-9-2 · Keep in mind that a high TDS level indicates high conductivity in the water. Products that Measure Conductivity While you can use many different instruments to measure the conductivity of boiler water, among the most effective instruments is a toroidal conductivity sensor, which comes with digital communication for better ease-of-use.

Water for the Boiler | Spirax Sarco

Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.

Its caustic concentration can be as high as 10,000-100,000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If the "free hydroxide alkalinity" is set too high or uncontrolled, then caustic gouging may result. Prevention of porous deposit formation (such as iron oxide) eliminates a place for caustic gouging to occur.

Heat Recovery from Boiler Blowdown TDS Control

The blowdown water released from the boiler is water at the saturation temperature appropriate to the boiler pressure. In the case of the boiler in Example 3.13.1 - 10 bar g, this temperature is 184°C. Clearly, water cannot exist at 184°C under atmospheric conditions, because there is an excess of enthalpy or energy in the blowdown water.
