The steam flow path arrangement is 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. Flue gas formed by the combustion of the fuel passes upwardly out of the furnace through horizontal gas pass through an opening(28) into rear gas pass(30).
