Abstract
1,246,517. Gas turbine plant. MOTORENUND TURBINEN UNION MUNCHEN G.m.b.H. June 12, 1969 [June 12, 1968 (2)], No.29926/69. Heading F1G. [Also in Division F4] A rotary regenerative heat exchanger comprises an annulus defined by a pair of mutually spaced circular walls, a plurality of heat exchange elements extending between the walls, each element being disposed within a respective duct whereby in operation gas flowing through the ducts will flow through the elements to effect heat exchange between the elements and the gas. The invention is described with reference to a heat exchanger 10 of a gas turbine engine, the rotational axis 11 of the exchanger being disposed at an angle to the axis of the engine. The heat exchanger drum comprises a series of circumferentially spaced matrices 21 each associated with a pair of guide members 22 which define ducts so that the exhaust gases flow outwardly as indicated by arrow 15 in Fig. 3 while the pressurized air flows inwardly as indicated by the arrow 27. The inner and outer walls of the drum are formed by grids 19, 20 while the side walls 17, 18 are closed walls. In Figs. 5 and 6 the exhaust gases and pressurized air flow axially through the drum instead of radially as in Fig.3. The drum comprises a plurality of circumferentially-spaced matrices 36 each associated with a pair of guides 37 which define ducts so that the exhaust gases flow as indicated by arrow 40, Fig. 6, and the air flows as indicated by arrow 42. The side walls of the drum are perforated at 35 while the inner and outer walls 31, 32 are closed. The turbines exhaust gases pass to space 14 and then radially through the drum, finally discharging through an exhaust outlet. Air from the compressor passes to space 26 then radially inwardly through the drum being pre-heated thereby and then passing to the combustion chamber. The two spaces are separated by a diaphragm and seal devices, 29, 28 adjacent the inner and outer peripheries of the drum.
