The tank and throat cooling is designed to cool by means of permanent and uniform air or water flow. The areas of the glass furnace which have to be cooled run the risk of damage from overheating and/or increased corrosion. This would result in a significant reduction in the life cycle of the furnace and increases the risk of tank leakage.
The HORN tank and throat cooling equipment is designed with special nozzles for precise cooling of the metal line which results in less corrosion of the tank blocks and a longer lifespan. The cooling takes place via different fans which suck air from the environment and transport this air through pipelines to the point which has to be cooled. For the tank and throat cooling, two to six (depending on the furnace size) cooling fans are normally used, whereby one of the fans is always designed as a stand-by fan in case one of the other fans is damaged.
The cooling air outlet nozzles are mounted on the exact level of the glass metal line since the corrosion of the refractory material is the highest at this point. There are also additional spare ports provided at the main manifold tube to supply additional cooling positions.
