How fast can the temperatures of the two catalytic converters be raised?

After stopping work for repairs, in order to resume operations as soon as possible, how much can the heating time for the two units be reduced?
We have carried out this process many times, and during the lining drying stage, we always follow the temperature rise curve strictly.
It seems that the rapid temperature rise took only 18 hours.
Haste makes waste. To be scientific, existence is the ultimate truth. Too short a time will affect the performance of the lining; it should not impact the device’s lifespan. Don’t focus only on the present, but consider the future as well......
It should be carried out strictly in accordance with the heating curve, without deviating from reality.
It is essential to strictly follow the red acceptance criteria for the lining material; if time is tight, why not discuss with the material supplier ways to reduce the drying time?
Generally, the heating rate should be slow during the first stage; after reaching 350 degrees Celsius, the heating rate can be increased. In the shortest case, it takes 24 hours, and this is when the device has undergone thorough heating and lining treatment.
If there are no major repairs to the lining, the startup time can be reduced to just over 20 hours from ignition to catalyst installation
Yes, for ovens that are restarted after a shutdown, it depends on the length of the shutdown period: if it’s a short shutdown of around 1 day, the temperature can be raised quickly; but if the shutdown lasts more than 3 days, then the temperature must be increased in accordance with the specified heating curve
If it’s the first time starting up, it’s better to increase the temperature gradually following the heating curve; if it’s not the first time, 14 hours is also acceptable
