Abstract

A system is provided for cooling high-temperature, high-pressure gasifiers having cooling tubes which extend vertically through the walls of the gasifier and are connected in a closed cooling water circulation system. In accordance with the invention, the cooling tubes are coated on the inside of the gasifier with a plasma or flame sprayed ceramic coating, preferably consisting of alumina, and are embedded in a ramming compound such as tamped clay.
