Abstract

771,638. Axial-flow and centrifugal compressors. SULZER FRERES SOC. ANON. June 22, 1955 [July 5, 1954], No. 18101/55. Class 110 (1). A plant for supplying air to metallurgical furnaces comprises a compressor having at least two stages and driven at constant speed, and a single-stage recuperator turbine having adjustable blading, to which air is supplied from an intermediate point of the compressor. Air is supplied to a metallurgical furnace 1 by a compressor comprising axial-flow low-pressure stages' 7 and one or more centrifugal high-pressure stages 8. The compressor is driven through step-up gearing (not shown) by a synchronous electric motor 3 and also through a coupling 4 (which may comprise disengageable gearing) by a single-stage turbine 5. The turbine 5 is driven by air extracted from the compressor upstream of an intercooler 11. Regulation of the pressure and quantity of air delivered to the furnace 1 is effected by varying the quantity of air diverted through the turbine 5, by means of adjustable guide vanes 14. The turbine 5 exhausts either to atmosphere, as shown, or into the suction pipe of the compressor. The high-pressure stage of the compressor may be of the axial-flow type.
