Abstract

540,797. Regenerators. HOWDEN & CO., Ltd., J., and ULANDER, P. H. N. April 29, 1940, No. 7620. [Class 64 (i)] To maintain the heating surface of a rotary heater above the dew-point of the flue gases without adding materially to the required total surface, the air is heated in two stages, in one of which the air is in contraflow to the gases and in the other in parallel flow with t he gases. In a heater of the Ljungstrom type, the gases flow from the inlet 29, Fig. 1, upwards between plates of a stage 22, then around a radial partition 24 and upwards through the plates of a stage 23 as indicated by lines 30. Air flows from the inlet 32 upwards through the stage 23 then through an external duct 34 to the space below a radial partition from which it flows downwards through the stage 22 as indicated by lines 33. The parallel flow section may be of the radial instead of the axial flow kind shown.
