Abstract

6128. Burdh, A. F. March 12. Condensers.-In a casing, flat plates are arranged in a parallel series so as to form shallow flat chambers alternately for the heating and cooling media. These plates are stamped or punched as shown, so that a series of small hemispherical or other bosses A' are produced on one (the cooling- water) side and a series of staggered parallel ridges A' on the other (steam) side of each plate. The plates are so set that the bosses and ridges on the sides of each chamber are opposite each other. Their ends are attached to the ends of the casing, and their edges to each other, by means of molten metal. In some cases, a single, long, bent plate may be used to form the series of chambers. The steam passes in by a conduit B<2> and is forced, by a baffle B<3> supporting a grid C which protects the joints of the chambers, to pass through this grid, any condensed steam passing through the openings b into the steam chambers. The condensed steam passes out through the conduit B<8>. The cooling- water passes in by the conduit B<10> and out by the conduit B<17> after traversing the water chambers. Soda or other cleansing-solution may be admitted to the steam conduit B' through an opening B<18> and a passage B<19> in the wall of the conduit, leading into a chamber B<20> formed by a recess in this wall closed by a perforated flange on the grid C. A baffle B<31> prevents steam from blowing back through the opening. The front parts of the steam chambers may be enlarged at the top and bottom.
