Abstract
A liner for use within a gasifier vessel includes a plurality of elongated channels and a plurality of ceramic sheaths. The elongated channels pass coolant through the gasifier. The ceramic sheaths surround the elongated channels.
Claims22
A liner for use within a gasifier vessel, the liner comprising:
- a plurality of elongated channels having an inner surface and an outer surface for passing coolant through the gasifier vessel;
- and
- a plurality of ceramic sheaths covering the elongated channels and aligned with each other to form a circular cross section and define an inner surface and outer surface of the liner, wherein each sheath covers one of the elongated channels, and wherein the sheaths are in thermal communication with the elongated channels so that the inner surface of the liner is cooled by coolant flowing through the elongated channels and slag is frozen onto the inner surface of the liner, and wherein the sheaths and the elongated channels are decoupled, wherein the plurality of elongated channels are tubes, wherein each tube includes a respective tip flange at an end thereof, wherein each of the plurality of sheaths are supported on the respective tip flange.
A gasifier comprising:
- a vessel;
- a plurality of elongated channels housed within the vessel, wherein each of the elongated channels has a head end, an aft end, an inner surface and an outer surface;
- a metal flange for connecting the head ends of each of the elongated channels;
- a plurality of ceramic sheaths, each sheath decoupled from but surrounding one of the plurality of elongated channels, wherein the ceramic sheaths are aligned with each other to form a circular cross section;
- and
- a liner having an inner surface defined by the plurality of ceramic sheaths, wherein the ceramic sheaths are positioned to be cooled by coolant flowing through the elongated channels so that slag freezes onto the inner surface of the liner, wherein a plurality of tips supporting the plurality of ceramic sheaths are attached to the plurality of elongated channels at the aft ends of the plurality of elongated channels.
