Embodiment Construction

[0013] It should be noted that although the embodiments of the present invention have been described with respect to the combination of an integrated gasifier and a syngas cooler, those of ordinary skill in the art will appreciate that embodiments of the present invention are not limited to combinations with only an integrated gasifier and syngas cooler. Syngas coolers are used in combination. Rather, embodiments of the present invention may be used with any one-piece container.

[0014] The following detailed description shows embodiments of the invention by way of example and not limitation. It is contemplated that the present invention has general application to cooling the internal components of containers to extend their life in industrial, commercial and residential applications.

[0015] As used herein, an element or step recited in the singular and preceded by the word "a" or "an" should be understood as not excluding plural elements or steps, unless such exclusion is...

Abstract

A method and system for an integrated gasifier (106) and syngas cooler (110) are provided. The system includes a gasifier including a reaction chamber (116), a syngas cooler (110) integrally formed with the gasifier and including at least one heat exchanger element (126), and a transition portion (112) integrally formed with the reaction chamber and the syngas cooler and extending therebetween, the transition portion further including a throat (114) extending between the reaction chamber and the syngas cooler, the transition portion further including a heat exchanger (126) circumscribing the throat.

Description

technical field [0001] The present invention relates generally to partial oxidation gasifiers and gas coolers, and more particularly to reducing wear on internal components of an integrated gasifier and gas cooler combination. Background technique [0002] At least some known gasification vessels include regions that are susceptible to Increased amount of wear. For example, but not limited to, the gasifier bottom transition, gasifier throat, and syngas cooler throat are areas of high wear on the refractory liner as the narrow flow path increases the mass flow of slag along the liner wall Rate. While some attempts have been made to mitigate the effects of adverse conditions affecting heat resistant materials, these attempts have often created other problems. For example, one known attempt to actively cool the affected area creates a vertical expansion gap in the throat liner between actively cooled and passively cooled sections. This gap would provide a potential leak pat...
