Abstract

A supercritical forced-flow once-through vapor generator circuitry in which the furnace enclosure consists essentially of three flow passes in a series-flow relationship. The first pass occupies the enclosure front wall, and the second and third passes occupy the enclosure rear wall and intermediate side walls. The invention is particularly useful for coal-fired generators of medium to large capacity wherein the three passes provide sufficient mass flow rates to cool the enclosure while at the same time employing normal sized tubes.
