Patent ID: 7547423

Claim:
A system for converting a carbonaceous material into a gaseous product, said system comprising: a gasification chamber spool including a ceramic matrix composite (CMC) liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the gasification chamber spool; an injector spool adapted to inject a dry slurry stream into the gasification chamber spool and impinge at least one reactant on the dry slurry stream to generate a chemical reaction that produces a gaseous product and the molten slag; and a heat exchanger (HEX) quench spool adapted to receive hot product produced by the gasification chamber spool, the HEX quench spool including a CMC liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the HEX quench spool and a plurality of CMC panels having a plurality of internal coolant channels, each of the plurality of CMC panels including orifices extending through the CMC panel and fluidly connecting at least one of the plurality of internal coolant channels with an interior volume of the HEX quench spool that receives the hot product produced by the gasification chamber spool.
