Abstract

112,792. Semmler, C. Jan. 6, 1037. Generating by indirect contact of heated air.- The waste heat of slag is utilized by granulating the slag by means of compressed air, then passing additional air through the granulated slag, the resulting hot air being used for heating a boiler, &c., and then again introduced for cooling the slag. The stream of molten slag r is granulated by an air jet d and is met by a stream of air as it falls over the baffle plates p. The heated air passes through a boiler k or other heat exchanging apparatus, descends the flue c and re-enters the uptake s, being circulated by a fan f.
