DEVICE FOR PROTECTING METALLIC SURFACES FROM CONDENSATES OF HIGH-TEMPERATURE CORROSIVE MEDIA IN TECHNICAL INSTALLATIONS

摘要

The supporting structure of a technical installation made of a material that is not resistant to corrosion and whose inner wall at least temporarily contains a corrosive and abrasive gas/vapor mixture and is protected from acid corrosion by a gas/vapor mixture barrier. This barrier is either placed between a fire-resistant coating (6) and the highly heat insulating layer (7) or is integrated in the fire-resistant layer (6) or in the heat insulating layer (7). The mechanical protection from the permeation of the gas/vapor mixture though the heat insulating insulation (7) up to the inner wall of the supporting structure enables a heat insulating material to be selected that has a distinctly reduced thermal conductivity and thus enables the temperature on the exterior of the supporting structure to be lowered whereby reducing the loss of energy and the increasing the level of industrial safety.
