What is Refractory Dry Out?

Refractory dry out is the controlled process of applying heat to a refractory lining to remove water from the lining system without causing damage to the refractory materials.

What is the purpose of Refractory Dry out?

The refractory is the heat-resistant material that lines high-temperature furnaces and reactors and other processing units, including commercial boilers. While refractory must be able to stand up to thermal stress, it also must be able to undergo physical wear and corrosion that comes from chemicals in the boiler.
Why is Refractory Dry Out important?

When refractory areas are installed inside a boiler, such as a screen seal, they are exposed to higher stresses, erosion issues, and elevated temperatures. These areas of refractory need the strengths that only a complete dry out can provide. This means the gas temperature for the hold points may have to be estimated.
It is well known that when you have completed a plant repair or new build, there is usually a need for dry out or heat up of any refractory lined installations and components. Done correctly this can help increase the performance & lifetime of your refractory installations.
