The DTS water-cooled hood system provides a hood design that can be used on Peirce-Smith converters or similar furnace vessels to allow converter off-gas systems to operate at higher temperatures. The system, which uses only one control valve,uses a closed-circuit cooling water system for low-pumping costs and minimal opportunity for oxygen entrainment in the water. An air-cooled converter hood can be replaced by a DTS water-cooled system during the rebricking shut down, meaning retrofitinstallation does not interfere with production.
