ROTARY REGENERATIVE HEAT EXCHANGER FOR HIGH TEMPERATURE APPLICATIONS ABSTRACT OF THE DISCLOSURE A rotary regenerative heat exchanger (10) is particularly adapted for use in exchanging heat from a hot gas entering the heat exchanger at a temperature in the range of 2000-3000F to low temperature air to be heated. An upper rotor (20) and a lower rotor (30) are supported concentrically about a rotor post (12) mounted for rotation successively through the hot gas and air flows at a vertical axis. The hot gas enters and the heated air exits through the top of the heat exchanger, while the cooled gas exits and the cold air to be heated enters through the bottom of the heat exchanger. The upper rotor (20) houses ceramic heat absorbent blocks (40) adapted to withstand the high temperatures existing in the upper portion of the heat exchanger, while the low rotor (30) houses typical metallic element suitable for use at more moderate temperatures.
