WATER COOLING WALL FOR DUAL TOWER TYPE GASIFICATION SYSTEM

摘要

A waterwall for a twin tower gasification system wherein the two towers are fluidically connected intermediate their ends. The waterwall comprises a plurality of tubes, a portion of which extend from the first tower to the second tower and define a cylinder. The portion of the tubes extending between the towers are twisted into a helix such that the portion of the tubes that define the lower portion of the cylinder at the first tower, define the upper portion of the cylinder at the second tower.
