Method for avoiding thermal stresses in glass lined vessels

摘要

The present invention minimizes the problem of thermal stresses in a glass lined vessel by providing a heat transfer sump in the bottom portion of the vessel. A heat transfer compartment is formed by enclosing the annular space between the exterior portion of the skirt and the bottom portion of the vessel by means of an annular ring. The heat transfer compartment is enclosed by the annular ring, the interior portion of the skirt, and the bottom portion of the vessel. The heat transfer compartment is adapted to receive and hold a heat transfer medium and in this manner form a heat transfer sump.
