  • Refractory vessel and lining therefor
    Patent number: 6840766
    Abstract: A refractory vessel that can be used as a gasifier for black liquor includes a generally cylindrical metal shell having a dome. A refractory shell has a cylindrical portion spaced inwardly from the metal shell and a dome portion that is spaced inwardly from the metal dome. The refractory shell is sized to provide an expansion gap between the liner and the metal shell. A selectively crushable liner is positioned in the gap. The liner has a predetermined yield stress that will provide controlled resistance to expansion of the refractory shell.
    Type: Grant

  • Torispherical dome for refractory vessel
    Patent number: 6705241
    Abstract: A refractory vessel has a generally cylindrical metal shell and an upper torispherical dome. A refractory liner lines the shell and the dome. A layer of skew blocks are positioned between the cylindrical shell portion of the refractory liner and the dome portion. A metal band is positioned outwardly from said layer of skew blocks for restraining radial expansion thereof.
