Abstract
A catalytic combustion and heat transfer device for use in a deep fat fryer is disclosed, characterized by increased efficiency and heat transfer. The device includes a hollow elongated heat exchanger having a generally oval interior cross-sectional configuration. A catalytic burner is mounted within a combustion end of the heat exchanger and a unique core buster and heat exchange fin arrangement is mounted within the flue end of the exchanger. The fin arrangement comprises a plurality of generally U-shaped tapered fins arranged in opposed pairs and connected with the inner side wall surface of the exchanger, with the leg portion of each opposed pair extending toward each other in spaced relation. The core buster is arranged between the opposed pairs of fins in contiguous relation with the free end edges thereof to define a plurality of channels within the fins, respectively. A spark ignition device is mounted adjacent the catalytic burner to ignite a combustion mixture supplied to the burner. Heat and flue gases are deflected by the core buster to the heat exchange fins and fin channels to increase the transfer of heat to the exterior surface of the heat exchanger.
