The dry out process is the last step to refractory installation.
A refractory dry out process is crucial after refractory installation before operations can begin.
This is because moisture is likely to gather once all the other refractory processes are applied.
Hence, it is important to know how a refractory company does the dry-out process for a successful boiler refractory repair procedure.
What is Refractory Dry Out?
What is boiler dry out? Also known as bake out is the removal of mechanical water and chemical water from the refractory lining.
Mechanical water – water content added during the mixing process
Chemical water – existing water content during refractory material manufacturing
More information on Refractory Heat Up
Basically, the boiler refractory dry out procedure is done within a boiler during the initial start-up.
Afterward, the mechanical water turns into steam and transpires from the refractory lined walls due to the heat.
As for the chemical water, it is removed by the upper hold points which helps it form the final bond with the refractory for maximum strength.

What are the steps to the refractory dry out process?
This rdo boiler process is essential to prevent any damages that can affect refractory linings.
Also, do note that the refractory tryout application is dried out either before operations have begun or after refractory repairs.
As a plant manager, you need to know the boiler dry out purpose and steps required for a successful dry out process for your refractory installation.

1. Consult the Refractory Supplier for Dry Out Schedule
Consulting a trusted refractory material manufacturer is the initial step of refractory drying process.
Mainly because they have extensive knowledge of the applied refractory products together with hands-on experience handling them.
Thus, they can help to set the right dry-out schedule based on the refractory material’s lining permeability, density, and thickness.

2. Thermal Profiles of Refractory Lining
Excessive heat is no stranger to refractory systems.
Moreover, the harsh temperature changes can severely impact the refractory application.
Therefore, it is crucial to know the exact thermal profile of the refractory material to lessen the risk of intense temperature rise.
This is because the refractory bricks may have low permeability.
Hence, it needs enough time to force the water content out of the lining without risking the refractory material’s performance.
3. Types of Refractory Linings
Refractory installers usually combine different compositions to make a refractory lining to suit a plant’s requirements.
Therefore, there will be variable properties that will affect the drying out process indefinitely.
This includes the refractory material quality or its thickness which can impact the water fluctuation and thermal profile of the refractory product.
Hence, the dry-out procedure for refractory relies heavily on the diversity of the refractory materials for a successful refractory application.

4. Properly Plan the Refractory Dry Out Procedure
All relevant parties including the refractory designer, supplier, refractory installer, and plant manager must work together for a seamless refractory installation.
It is essential that cooperation is needed to create an accurate dry-out schedule for high-performance operations.
Nonetheless, make sure the total refractory installation cost and efforts are optimized by hiring a refractory company equipped for the refractory application.
