SUPERHEATER STEAM FLOW ARRANGEMENT

摘要

A steam flow path arrangement for covering the walls of the rear gas pass of a steam generator. The entire flow passes down the sidewalls with a minor portion then passing up through the rear wall to a superheater inlet header at an intermediate elevation. The major portion of the flow passes up the front wall and through hanger tubes to a roof header. From there the major portion passes across the roof and down the rear wall to the superheater inlet header at the intermediate elevation.
