Abstract

172,381. Lavaud, D. S. de, Clark, B. F., and Baines, C. W. Aug. 31, 1920. Generating by hot metal and the like.-In means for utilizing waste heat given off by heat-treated articles during cooling, heat utilizing means, such as a steam generator, is provided in the cooling chamber to which the articles are passed from a heating chamber. Means are also provided for passing the waste gases from the heating chamber during the period when articles are not being treated, directly into the cooling chamber wherein their heat is absorbed by the heat utilizing means. In the apparatus shown, the heating chamber A communicates by means of a passage A<2> with the cooling chamber B in which is situated a steam generator b. The articles are passed through the chambers A and B on rails D by a conveyer C and are delivered to and through a quenching or coating bath J. Situated beneath the cooling chamber B is a passage M communicating with vertical shafts Q leading to the cooling chambers and with regenerators beneath the heating chambers and connected therewith by vertical shafts A<3>. Dampers N and 0 adapted to be raised and lowered alternately by a wheel P are provided in the passages M on each side of a tunnel L leading to a smoke stack. Normally the damper 0 is down and the damper N raised so that when articles are being treated, the hot gases from the heating chamber pass down the shafts A<3>, through the regenerators a and away to the stack through the passage M. When articles are not being treated, the damper N is lowered and damper 0 raised so that the gases from the furnace pass through the cooling chamber wherein their heat is absorbed by the heat-utilizing means b, down the shaft Q and away to the stack through the passage M.
