Patent ID: 8398730

Claim:
A gasification reactor comprising: a first stage that is at least partially formed by a first wall, wherein said first stage comprises a cavity defined at least partially by said first wall, said cavity configured to produce a first synthetic gas (syngas) stream; a second stage coupled in flow communication with said first stage, wherein said second stage is directly above said first stage and is at least partially formed by said first wall; at least two manifolds coupled to said first wall such that each of said at least two manifolds penetrates through said first wall to facilitate channeling fluid into at least one of said first stage and said second stage; a first passage defined at least partially by at least a portion of said first wall and a second wall, said first passage is in heat transfer communication with said first wall; a second passage defined at least partially by at least a portion of said second wall and a third wall, said second passage is coupled in flow communication with said cavity and said first passage, said second passage radially outward from said first passage, said first passage receives at least a portion of said first syngas stream discharged from said second passage; and at least one nozzle scrubber assembly that is at least partially formed within said second passage, said at least one nozzle scrubber is oriented to receive at least a portion of the first syngas stream.
