Abstract
Abstract A water jacket face of a burner nozzle for a synthesis gas generator is protected from hot gas corrosion by an annular heat shield of high temperature material tiles. Angular segments of a tile annulus around a burner nozzle orifice are secured to the water jacket face by furnace melted, high temperature brazed metal. The metal water jacket face along radial joints between adjacent tiles is protected by stepped or scarfed lap joints.
