Abstract

A once-through vapor generator in which the roof and heat recovery area rear wall comprise a single continuous downflow pass feeding the generator primary superheater. An outlet header for the pass, at the lower end of the pass, also serves as the inlet header for the primary superheater, flow from the header being upwardly in the superheater. A plurality of diaphragms at spaced intervals along the axis of this common header divide the header into a plurality of separate sections which in turn form in the downflow pass and superheater a plurality of narrow-width parallel down-up flow circuits. The invention prevents the occurrence of recirculation of flow at low loads within the roof and heat recovery area rear wall.
