Abstract
829,884. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. April 27, 1956 [April 29, 1955], No. 12948/56. Class 64(1) Leakage losses through the clearance gap between the rotor 4, Fig. 1, and the cover. plate 3 of a thermal regenerator are reduced by directing a current of fluid transversely of the gap. Air escaping from a duct 1 is drawn through a radially extending slot in the plate 3 by a nozzle 7 and blown by a fan 6 into the atmosphere or back into the duct 1 so that leakage into the flue duct 2 is reduced or eliminated. The action of the fan 6 may be reversed, the sealing current being drawn from either the atmosphere or the flue gas. The rotor is preferably constructed so that the radial edge of a partition, a grating 9 or a transfer plate always intervenes between the edge of the plate 3 and the nozzle 7. Fig. 3 shows a modification in which the fan circulates sealing fluid between a pair of nozzles 7, 8 which may be oppositely or similarly inclined to the cover plate 3. The level of the plate 3 between the nozzles may be slightly raised to improve the sealing effect. Suction or pressure slots may be distributed over the entire plate 3. The discharge and suction pressures are above and below those in the air and flue ducts, respectively.
