1. A reactor vessel comprising:
an entrained flow gasifier comprising a top portion and a bottom portion, with a feed stock injector at the top portion; the bottom portion including a dry bed zone having dry solids material that is situated to initially catch falling slag in the entrained flow gasifier; a cooler device to remove heat from the dry bed zone at the bottom portion; a dry solids discharge beneath the dry bed zone; a particle separator operable to produce a clean stream and a separated dry solids stream; a discharge line connected between the entrained-flow gasifier and the particle separator, the discharge line arranged to receive a product stream from the entrained-flow gasifier and convey the product stream to the particle separator; and a return line connected between the particle separator and the entrained-flow gasifier, the return line arranged to receive the separated dry solids stream from the particle separator and convey the separated dry solids stream to the dry bed zone at the bottom portion of the entrained-flow gasifier. |
