Patent attributes
A stave cooler for a furnace that always includes a liquid coolant piping cast inside. A stave cooler body includes a hot face and a backside and a liquid coolant piping cast inside between the hot face and the backside. A single steel collar on the backside of each stave is engineered to support the entire weight of the stave cooler. Any and every external connection of the liquid coolant piping are collected and routed together through the single steel collar. These stave coolers are limited to those mountable only from the inside of steel containment shells provided with a matching penetration. The single steel collar and a cover plate accommodate and provide a gas-tight seal by a continuous welding of the single steel collar to each steel containment shell.
