Definitions

  • This invention relates generally to partial oxidation gasifiers and gas coolers and, more particularly, to reducing wear on internal components of an integral gasifier and gas cooler combination.
  • At least some known gasification vessels include areas that are prone to elevated amounts of wear due to the flow characteristics of the raw effluent gas passing these areas and the adverse conditions of temperature, pressure, and chemistry these areas are exposed to.
  • a gasifier bottom transition, a gasifier throat, and a syngas cooler throat are high wear zones for refractory linings because the narrow flow path increases the mass flow rates of molten slag along the lining wall.
  • some attempts to mitigate the effects of the adverse conditions affecting the refractory have been tried, the attempts have tended to create other problems. For example, one known attempt to actively cool the affected areas resulted in a vertical expansion gap in the throat lining between the actively cooled and passively cooled section.
  • the gap provides a potential leak path of syngas into the annular space behind the vertical tube cage.
  • Another attempt used a vertical steel cylindrical gas barrier with a flanged bottom behind the throat refractory to prevent gas from escaping into the stagnant annular zone.
  • the steel cylinder is not cooled, therefore leading to either overheating of metal or shorter refractory life.
  • the inside diameter of the flow path in the throat is constrained by the inside diameter of the flanges of both the gasifier and syngas cooler. The flow path diameter cannot be changed without significantly altering the steel vessels.
  • Providing a gasifier having an integrated cooler formed integrally with the gasifier eliminates a forged flange on the gasifier vessel and a forged flange on the cooler vessel. Elimination of these two large flanges in the integrated gasifier/cooler significantly reduces the cost of the gasifier/cooler over the separate gasifier and cooler configuration. Elimination of the flange-to-flange joint between the gasifier and the syngas cooler permits the combined axial length of the two vessels to be significantly reduced. The reduced length reduces the thermal growth of the combined vessel, thus reducing the mismatch with the interconnecting piping (injectors, steam drum, steam piping, instrumentation) that are fixed to the support structure which is at ambient temperature with minimal thermal growth. Elimination of the flange-to-flange joint also improves the integrity of the vessel and facilitates eliminating components (flanges, supports, etc.) and reducing erection operations.
  • an integrated gasifier and syngas cooler includes a gasifier including a reaction chamber, a syngas cooler integrally formed with the gasifier and including at least one heat exchanger element, and a transition portion integrally formed with the reaction chamber and the syngas cooler and extending therebetween, the transition portion further includes a throat extending between the reaction chamber and the syngas cooler and the transition portion further includes a heat exchanger circumscribing the throat.
  • an integrated gasifier and syngas cooler system in another embodiment, includes a first pressure vessel portion surrounding a gasifier reaction chamber wherein the first portion extends from a vessel head to a lower end.
  • the system also includes a second pressure vessel portion surrounding a gas cooler configured to cool a hot raw effluent gas stream from the gasifier reaction chamber.
  • the second portion extends from an upper end vertically downward towards a solids removal end.
  • the system further includes a transition portion extending between the lower end and the upper end wherein each of the first portion, the second portion, and the transition portion are in substantial vertical coaxial alignment along a central longitudinal axis of each portion.
  • the system includes a throat coaxially aligned with each portion and extending therebetween for the free passage of the hot raw effluent gas stream from the gasifier reaction chamber to the gas cooler, the throat is lined about a radially inner surface with a refractory material.
  • the system further includes a concentric coaxial vertical tube cage surrounding the throat along at least a portion of a length of the throat, and a plurality of annular anchoring rings coupled to at least one of the first portion and the tube cage, the anchoring rings extending radially inward and are configured to support the throat refractory material.

  • Upper shell 104 includes a bottom exit passage 116 along a central longitudinal axis 118 of vessel 100 and an upper head 120 that includes a coaxial inlet opening 122 for the insertion of a downwardly discharging gasification burner (not shown).
  • Throat 114 includes a converging entrance
  • Upper shell 104 includes a thermal refractory lining 124 surrounding gasification reaction zone 106 and extending radially between upper shell 104 and reaction zone 106 .
  • Throat 114 is a vertical cylindrical annular shaped elongated conduit lined with a thermal refractory brick lining 126 .
  • Throat 114 is generally coaxial with upper shell 104 and lower shell 108 and extends therebetween for the free passage of the hot raw effluent gas stream flowing downwardly from reaction zone 106 to gas cooler 110 in lower shell 108 .
  • an “axial” direction is a direction that is substantially parallel to axis 118
  • “upper” and an “upward” direction is a direction that is generally towards inlet opening 122

  • upper shell 104 includes a first layer 202 of refractory brick stacked circumferentially about an outer periphery of reaction zone 106 , and a second layer 204 of refractory brick stacked radially outward from first layer 202 .
  • First layer 202 is supported at a lower end 206 by a first annular anchoring ring 208 that extends radially inward from upper shell 104 .

  • First layer 202 and second layer 204 are stacked such that seams between adjacent bricks in first layer 202 do not align with seams between adjacent bricks in second layer 204 .
  • Such misalignment presents a labyrinthine path between reaction zone 106 and upper shell 104 that facilitates preventing hot raw effluent gas from reaction zone 106 from leaking from reaction zone 106 and entering a space 212 adjacent upper shell 104 , where corrosive constituents of the hot raw effluent gas can attack upper shell 104 .
  • Transition portion 112 includes a tube cage comprising a membrane wall of cooling tubes 214 extending circumferentially around throat 114 .
  • a stagnant annular space 216 extending radially outward from cooling tubes 214 to transition portion 112 provides an area for risers and downcorners (both not shown) that supply water and remove water and steam from cooler 110 .

  • an abutting joint between first layer 202 and sloped layer 222 is vertically aligned such that first layer 202 and sloped layer 222 may slide past each other relatively freely during periods of differential expansion and contraction.
  • Such slidable engagement facilitates avoiding compression of first layer 202 and sloped layer 222 which may cause cracking of first layer 202 and/or sloped layer 222 and to avoid forming gaps between first layer 202 and sloped layer 222 .
  • Stagnant annular space 216 is positioned outside refractory lined transition throat cylinder 114 and inside transition portion 112 and has an increased volume compared to a flanged joint configuration. This increased volume permits an embodiment of the present invention with boiler feed water piping and support structure inside annular space 216 .
  • the embodiment reduces thermal stress of pipe components and joints with the vessel due to thermal expansion mismatch by permitting more flexible pipe routing.
  • the embodiment also provides sufficient space to route a top header (not shown) into annular space 216 above a horizontal tube wall (not shown).
  • the embodiment adds additional tube panel surface area inside the hot gas path under the horizontal tube wall that increases the heat recovery performance or reduces the total axial length of the syngas cooler assembly. Additionally, the embodiment simplifies the support structure for the vertical tube panels by permitting direct connection to the vessel wall, which frees up more annular space for better access and design flexibility.
  • FIG. 3 is a schematic diagram of a throat area of a vessel 300 in accordance with another embodiment of the present invention.

  • FIG. 4 is a schematic diagram of a throat area of a vessel 400 in accordance with another embodiment of the present invention.

  • Embodiments of the present invention also permit gas flow moderation and a longer life transition point, an expansion feature of the gasification portion-to-throat transition brick allowing thicker brick for longer life at a high wear point, a ship lap expansion joint, a steam cooled refractory brick lining, modified support features of gasifier sidewall, gasifier transition, gasifier throat and syngas cooler throat linings, an integral gasifier and syngas cooler vessel, and a flexible flow path diameter and shape in the refractory lined throat wherein the variable diameter can be realized using stepwise increase in lining thickness.
  • the steam cooled refractory lining in the transition and/or throat allows longer run life and less down times for refractory replacement, which increases the availability of gasification process and reduces operation cost.
  • the steam cooled refractory lining also adds flexibility in adjusting syngas velocity and/or mass and momentum flux exiting the throat by means of variable diameter in the refractory lined throat. Active cooling of the refractory lining is accomplishing by extending the steam cooled tubes from the syngas cooler into the gasifier and/or tube cage.
  • the integrated vessel and refractory lining permits the flexibility of varying the refractory lined throat flow path diameter and shape without alternating the steel vessel flanges.
  • the throat shape could be cylindrical, conical, or flaring out with the diameter increasing as the flow approaches the downstream exit of the throat.
  • embodiments of a method and system for an integrated gasifier and syngas cooler system provides a cost-effective and reliable means for eliminating the horizontal flange-to-flange joint between the gasifier and the syngas cooler using instead a non-continuous and integral vessel that encloses the refractory-lined gasification reaction chamber and the syngas cooler heat exchanger internals together in the single vessel. Additionally, embodiments of the present invention provide sufficient internal volume in the gasifier-to-syngas cooler transition area to extend the throat tube cage to the bottom transition of the gasifier, which enables steam cooling of the refractory lining of the entire length of the throat, and/or of the entire throat plus the 45 degree bottom transition in the gasifier.
  • the steam-cooled refractory lining has a longer life that without active steam cooling in the throat. Further, the supports of the refractory linings in the gasifier sidewall, transition, and throat sections accommodate the expansion and contraction of the gasifier sidewall, transition, and throat sections during periods of temperature changes. Accordingly, direct leak paths in the refractory lining for syngas to flow into the transition area are substantially eliminated. As a result, the methods and systems described herein facilitate gasification and cooling of a fuel in a cost-effective and reliable manner.
