Abstract
For multi-cell, mechanical draft, vacuum steam condensers, a design of a noncondensible gas removal system that isolates bundles and fan cells from external/internal influences and gas/vapor interchange and allows bundles to operate in a reverse air-flow direction, all of which promotes freeze protection and improved performance.
Claims19
A multi fan-cell system for condensing steam vapors contaminated with air and gases, the system being isolated into single fan cells for the removal and discharge of its non-condensable gas/vapors, each fan cell having one fan and a predetermined number of steam condensing bundles which includes a front header, finned tubes arranged in a plurality of stacked and tubular rows and rear header means whose gas/vapors are extracted and isolated from all other fan cells by a vacuum-producing ejector for each row of each fan cell directly coupled to the rear header means by pipe and manifold means all located and installed within the confines of the fan cell they serve.
