CONTINUOUS STEAM GENERATOR WITH EQUALIZING CHAMBER.

摘要

An evaporator (10) for evaporating a liquid includes a plurality of harps (20) disposed within a duct or chamber such that a heated fluid flow (22) (e.g., heated gas or flue gas) passes through each successive row of harps (20) of the evaporator (10). Each of the harps (20) includes a lower header (24), a plurality of lower tubes (26), an intermediate equalizing chamber 28, a plurality of upper tubes (30), and an upper header (32). The lower tubes (30) are in fluid communication with the lower header (24) and extend upward vertically from the lower header. The upper ends of the lower tubes (26) are in fluid communication with the equalizing chamber (28). The upper tubes (30) are in fluid communication with the equalizing chamber (28) and extend upward vertically from the equalizing chamber. The upper ends of the upper tubes (30) are in fluid communication with the upper header (32).
