The dry-out of a secondary reformer requires special attention on the temperature of the steel mantle. An outside insulation is fixed to the mantle to achieve the needed temperature of at least 100°C. This ensures
the refractory material being thoroughly dried and no water remaining in single segments. During the drying process the insulation is removed again to not risk an overheating of the steel mantle.
FCC-facilities consist of several different plant components. In contrast to dry-outs of completed plants these parts are often dried at the manufacturer and later integrated in the complete system.
A heater has concreting especially in the floor area, which is why this region needs to be taken into account. These type of facilities are usually predried up to ca. 260°C, whereby the heater, chimneys, Breechings and pipings need to be dried seperately.
