Waste Heat Cooling Systems

In the in-bath lance smelting technology, the brick-lined furnaces and hoods are typically surrounded by a water cooled jacket. Oschatz supplies a furnace and hood cooling system that is integrated into the evaporation system of the waste heat boiler. These components are designed as gas-tight welded membrane walls. In order to protect the membrane walls from excessive heat loads, they are fitted with studs onto which a thin castable layer is attached. The lifetime of these components complies with the usual average lifetime of boiler pressure components. In contrast, the brickwork of an originally water cooled construction needs to be relined at least once a year. The engineering concept developed by Oschatz leads to significantly less downtime, resulting in significantly increased production capacity and therefore assures that the whole plant is more economical.
