FURNACE TUBE ARRANGEMENT FOR STEAM GENERATOR

摘要

A furnace tube arrangement for a steam generator is described. A plurality of furnace tubes disposed longitudinally form a generally planar wall structure into which burner throats are let at least two longitudinally spaced levels in familiar manner. Burner throats at the respective levels are so disposed that a vertical mid-line of each throat at a first level is laterally offset from a vertical mid line of a corresponding throat at a second level.
