FAQ Refractory Dry-Out

1. What is the difference between curing, dry-out, and heat-up?

    

   • Curing refers to the hardening of cement-bonded materials such as castables.
   • Dry-out is the controlled removal of moisture still present in the refractory lining after curing.

   • Heat-up is the temperature increase to operational conditions of the system after dry-out. Each of these steps requires specific techniques, temperatures, and rates to prevent damage.

      

2. How long does a typical dry-out procedure take?

   
   The duration depends on the volume and type of lining. For medium to large industrial installations, a dry-out cycle can take up to 48 hours or more. Our engineers always develop a custom temperature curve, complete with timetable and monitoring, tailored to the specific installation.

3. What are the risks of an improperly executed dry-out?

   
   Cracking, moisture explosions in the lining (“spalling”), delayed commissioning, damage to equipment, and even safety incidents. Correctly following the temperature curves is crucial.

4. Which fuel types can be used for the dry-out process?

   
   We offer both gas- and oil-fired units. Depending on the ATEX classification, location, and availability, we will recommend the appropriate system.

5. Can your systems be used in ATEX zones?

   
   Yes. We have ATEX-compliant installations and follow strict HSE protocols when working in explosive atmospheres.

6. How are the temperature curves monitored and recorded?

   
   Using data logging and thermocouples at strategic points. All data is automatically recorded and compiled into a report that is provided afterward.

7. Will we receive a report with the logging afterward?

   
   Yes. Our standard service includes a technical report with temperature curves, incident logs, and process evaluation.

8. Is it possible to run the process 24/7?

   
   Absolutely. For complex or critical applications, we offer 24/7 monitoring and execution to minimize lead times.

9. How is personnel and equipment safety ensured?

   
   Our operators are specifically trained for dry-out applications and follow established HSE procedures. We also provide gas detection, heat-resistant barriers, and emergency response plans.

10. Can you adopt a temperature curve design from a third party?

    
    Yes. We can implement an existing curve provided it is validated by our engineering team. If needed, we will recommend optimizations for improved safety or speed.
