ABSTRACT:
The present invention is an arrangement of seals for an air heater used to preheat the intake air of a combustion process. Flexible seals and torsion bars are utilized in order to allow the flexible seals to adjust angle and properly fill the void space to be sealed. Also, a combination of sealing elements are used on the circular seal of the present invention in order to create a tortuous path for gas flow through the seals. The present invention offers many advantages over seals found in the prior art including improved wearability and low maintenance.
