Abstract: A system includes a syngas cooler configured to cool a syngas. The syngas cooler includes a vessel with a head portion and a first opening and a first pipe that extends through the first opening. The first pipe is configured to convey a heated fluid out of the vessel. A first flanged connection is disposed about the first opening, wherein the first pipe extends through the first flanged connection and is coupled to the flanged connection.

Abstract: A system includes a syngas cooler and a compatible seal gas system. The syngas cooler may be configured to cool a syngas. The compatible seal gas system may be configured to supply a compatible seal gas to a seal of the syngas cooler. The seal may be configured to block the syngas from a passage between an outer wall of the syngas cooler and a tube cage of the syngas cooler.

Abstract: A vessel for use in a gasification system is provided. The vessel includes a shell and a heat exchange structure positioned within the shell. The heat exchange structure defines a central cavity configured to receive and to direct a syngas to a quenching portion positioned downstream of the central cavity along a syngas path. A passageway is disposed between the shell and the heat exchange structure. A liquid seal is positioned upstream of the quenching portion, and the liquid seal is configured to block transport of at least one of the syngas between from the quenching portion into the passageway and inert gas from the passageway into the quenching portion.

Abstract: A system includes a particulate removal system configured to remove particulates from a syngas to generate a treated syngas and a particulate flow. The particulate removal system includes a shell. The shell includes a syngas inlet configured to receive the syngas, a syngas outlet configured to discharge the treated syngas, and a particulate outlet configured to discharge the particulate flow. The particulate removal system also includes a particulate collection surface disposed in the shell and configured to adhere the particulates from the syngas to the particulate collection surface as the particulate collection surface rotates toward the syngas and to separate the particulates from the particulate collection surface as the particulate collection surface rotates away from the syngas.

Abstract: A system includes a gasifier. The gasifier includes a refractory disposed about a gasification chamber and an enclosure disposed about the refractory. The system also includes an ignition device configured to extend into the gasification chamber and to initiate a gasification reaction within the gasification chamber with a refractory temperature of less than approximately 982° C.
