Abstract
A regenerative rotary air heater, comprising a generally circular rotor (1) arranged to rotate in a cylindrical casing (2), which casing has an air inlet (3) and an air outlet (5) for combustion air to be preheated and has a gas inlet (6) and a gas outlet (4) for exhaust gas, the rotor (1) being constructed with radial plates (8) having radial seals, wherein top and bottom sector plates (10, 11) are provided to separate air and gas sides of the casing (2), and wherein the air heater has one or more of the following features: 1) balance weights (14, 19) provided to enable hinged sector plates (10, 11) to follow rotor deformation; 2) the top and/or bottom sector plates (10, 11) are provided with extensions (21) so that the number of radial seals in contact with the sector plates is increased; 3) circumferential sub-division plates (9) provided beteween the radial plates (8) extend the full height of the radial plates and are sealed against the sector plates (10, 11); 4) circumferential seals between the rotor (1) and the casing (2) comprise a seal mounting bar (24) inclined at a suitable angle to a seat (22) and a seal (23) secured to the mounting bar (24); 5) hinged top and bottom sector plates (10, 11) are connected by rigid links (31) to adjust and maintain the rotor/sector plate gap.
