Embodiment Construction

[0027] figure 1 A reactor for the production of synthesis gas by gasification of a carbonaceous feed is shown. The reactor comprises a vessel 1 enclosing a combustion chamber 6 in its upper half. The vessel 1 is provided with a syngas outlet 7 at the bottom end of the combustion chamber 6 and with two pairs of diametrically positioned burners 2 . Via this outlet 7 , the produced synthesis gas and slag formed as by-products are discharged from the combustion chamber 6 . Each burner 2 is provided with supply conduits for oxidant gas 3 and carbonaceous feed 4 .

[0028] The combustion chamber 6 is surrounded by a substantially airtight wall assembly 8 consisting of interconnected parallel vertical tubular ducts 10 (for example, interconnected by fins). Such wall assemblies are also referred to as membrane walls. Tubular conduits 10 run from a common distributor 12 to a common header 11 . The dispenser 12 is provided with a series of capped collars 15 opposite the tubular con...

Abstract

Method of assembly of a carbonaceous feedstock gasification reactor comprising a gasifier unit confined by a tubular burner wall, the burner wall comprising a tubular wall assembly comprising a plurality of tubular conduits through which a flow path extends between a distributor and a header, each flow path crossing a passage opening in a seat for a flow restrictor wherein for each conduit, the wall assembly comprises an opening bordered by a collar wherein the open end of the collar is closed by a cap and wherein the wall assembly is arranged within the pressure vessel without the flow restrictors and subsequently the distributor, the conduits and the header are flushed and / or boiled out and the caps removed from the collars, the flow restrictors positioned and the caps put back to close off the open ended collars.

Description

technical field [0001] The present invention relates to a tubular wall assembly comprising a plurality of tubular conduits arranged in parallel, interconnected to form an airtight structure, each tubular conduit at one end connected to a common distributor and at the other end to a common header, wherein a flow path extends through each conduit between the distributor and the header. The invention also relates to: an insertable flow restrictor for such a wall assembly; and a gasification reactor comprising such a wall assembly for the partial combustion of a carbonaceous feed; a A method of assembling such a reactor; and a method of operating such a reactor. Background technique [0002] Such wall assemblies are used in particular as walls for burner units in gasifiers for the production of synthesis gas or synthetic gas by partial combustion of a carbonaceous feed such as coal dust. Examples of such wall assemblies are disclosed in GB 1 501 284 and WO 2008 / 110592. During...
