Abstract

834,156. Furnace recuperators. ESCHER, H. Feb. 26, 1958 [April 12, 1957], No. 6193/58. Class 64(1) In a combustion furnace recuperator, air or other gas is heated in flowing through an annular jacket surrounding a conduit 1 through which hot gases from a furnace 3 are passed. Hollow fins extend from the conduit 1 into the heating gas stream and a proportion of the air or gas to be heated is directed through these hollow fins whilst the remainder flows through the jacket, the two streams being reunited in the lower and unfinned portion of the jacket surrounding the lower and mainly radiant heating zone 12 of the heating gas conduit 1. In the upper and coolest zone 14 of the conduit 1 where heating is mainly by convection, a guide tube 23 is provided, the upper end of which is closable by a valve 25. The valve 25 is constructed for simultaneous operation with a valve or cover 5 at the outlet end of conduit 1. Under conditions of maximum flow of the heating gas both valves are open and some of the gas flows through the guide tube which then heats the fins and conduit 1 by radiation. Under a partial loading, when the flue gases are relatively cool, the valves are lowered so that the valve 25 is closed. Hot gases are then directed in the zone 14 only through the space between the guide tube and the conduit 1 before passing to waste. Whirler vanes 26 may be provided at the gas entry end of guide tube 23.
