A syngas cooler system includes a pressure vessel, a conduit, a plenum, a plenum, a conduit, and a bellows assembly. The pressure vessel includes a throat and a dome adjacent to the throat. The throat includes an area of excess heat, and the dome includes an area of deficient heat. The plenum extends between the throat and the bellows assembly. The bellows assembly is coupled at least partially within the dome. The conduit is coupled to the plenum for channeling a flow of purge fluid from external to the pressure vessel into the plenum such that purge fluid transfers heat from the area of excess heat into the area of deficient heat to facilitate reducing temperature differential stresses within the dome and the pressure vessel.

Methods and systems for controlling temperature in a vessel

A pump used in a gasification system, the pump comprises a housing having an inlet and an outlet, a rotor supported within the housing for rotation relative to the housing, the rotor comprising a hub, a plurality of disks spaced apart by sections of the hub, and defining a plurality of transport channels for transporting solid carbonaceous feedstocks for the gasification system, and an interior feedstock facing surface adjacent to the solid carbonaceous feedstocks, wherein at least a portion of the interior feedstock facing surface is coated with a coating.

Pump used in gasification system

A system for preheating a pressure vessel includes a throat including an area of excess heat and a dome having an area of deficient heat. The throat includes a conduit extending from a pressure vessel opening to the pressure vessel interior. A plenum is defined between the throat and a seal within the dome. The throat extends from the dome toward a dome floor. The floor is substantially perpendicular to the throat. A conduit is coupled to the plenum and channels a flow of purge fluid into the plenum wherein heat from the throat is transferred to the flow of purge fluid and carried by the flow of purge fluid into the area of deficient heat via a gap defined between the seal and the floor such that the flow of purge fluid reduces temperature differential stresses within the pressure vessel and purges the area of deficient heat.

A system includes a gasifier, which includes a reaction chamber configured to convert a feedstock into a synthetic gas, a quench chamber configured to cool the synthetic gas, a quench ring configured to provide a water flow to the quench chamber, and a quench ring protection system configured to protect the quench ring from the synthetic gas or a molten slag. The quench ring protection system includes a protective barrier disposed within an inner circumferential surface of the quench ring. The protective barrier substantially overlaps the inner circumferential surface in an axial direction along an axis of the quench ring.

System and method for protecting gasifier quench ring

A gasification quench chamber is disclosed. The gasification quench chamber includes a reservoir that contains liquid coolant in its lower portion and an exit for the cooled syngas in its upper portion; a dip tube that is configured to introduce a syngas mixture to contact the liquid coolant which produces the cooled syngas; a cooling device configured to further cool the cooled syngas in its upper portion; and a stability device in the lower portion that is configured to mitigate coolant level fluctuation and sloshing. In an embodiment of the quench chamber, the cooling device includes a heat exchanger pipe. A quench chamber and scrubber assembly is also disclosed.

Gasification quench chamber and scrubber assembly

In one embodiment, a gasification system component, such as a quench unit or scrubber may retain of pool of a cooling fluid for cooling another fluid. The gasification system component includes a flow damping mechanism designed to dampen flow of the cooling fluid, the other fluid, or both, within the gasification system component. The flow damping mechanism may be disposed in an inner chamber formed between a dip tube and a draft tube or disposed in an outer chamber formed between the walls of the gasification system component and the draft tube. The flow damping mechanism also may be disposed between the inner chamber and the outer chamber.

A method of assembling a syngas cooler is provided. The method includes coupling a supply line within a cooler shell, coupling a heat transfer panel within the cooler shell, and coupling a heat transfer enclosure within the cooler shell such that the heat transfer enclosure substantially isolates the heat transfer panel from the cooler shell. A manifold is coupled in flow communication with the supply line, the heat transfer enclosure, and the heat transfer panel.

Method and apparatus for heat recovery within a syngas cooler

A system includes a solid feed fuel pump. The solid feed fuel pump includes a solid feed flow path configured to route a solid fuel flow from an inlet to an outlet. The solid feed fuel pump also includes a vent including a filter, wherein the vent is configured to discharge fluid flow that is opposing the solid fuel flow.

System to vent solid feed pump

A system, comprising a seal segment including a cable fastener. The system also includes a syngas cooler component that includes a cable guide, where the cable guide may route a cable coupled to the cable fastener to enable the cable to pull the seal segment into a mounting position.

System for installing a seal in a syngas cooler

A syngas cooler for use in a gasification system is described that includes a head portion including a plurality of conduit headers. The syngas cooler also includes an annular shell portion including a plurality of conduits, the plurality of conduits configured to be coupled in flow communication with the plurality of conduit headers. The syngas cooler also includes a quench portion configured to remove particulates entrained in a flow of syngas flowing through the syngas cooler. The head portion and the shell portion are configured to be coupled together with a circumferential seam weld.

Methods and systems for a vessel preheating system are provided. The system includes a pressure vessel including an area of excess heat and an area of deficient heat, a plenum defined between the area of excess heat and the area of deficient heat, and a conduit configured to couple a flow of purge fluid from external to the vessel into the plenum wherein heat from the area of excess heat is transferred to the flow of purge fluid in the plenum and the heat is carried by the flow of purge fluid into the area of deficient heat such that the flow of purge fluid purges the area of deficient heat.

Methods and a system for shielding cooling tubes in a radiant syngas cooler. The heat shields may prevent direct contact between heated syngas and the cooling tubes. The heat shield may be mounted to a header that also attaches to the cooling tubes. The heat shield may also be separated from the cooling tubes or, alternatively, the heat shield may be coated onto the cooling tubes. Furthermore, prolonged exposure to the heated syngas may corrode the heat shield.
