<p>A rotary regenerative air preheater has a rotor (14) which is divided into sectors (20) by diaphragm plates (34). Mounted between these diaphragms are support gratings (40) which support the heat exchange baskets (22) with there being at least two circumferentially adjacent full-wrapper baskets on each support grating. The gratings include radial seals (48) which extend axially into the spaces between these adjacent baskets to provide a seal to minimize circumferential fluid flow. Attached to the radial seals at the axial ends of the rotor are seal strips (50, 52) which form a seal with the sector plates (24) on the rotor housing (12) thereby forming a double seal to minimize cross flow between the gas side and the air side.</p> |
