ABSTRACT:
An infrared heater for a fluid immersion apparatus such as a commercial deep fat fryer includes a burner whose burner element is made from woven ceramic fibers, preferably formed as a cloth. The burner can also include a wire mesh or screen for supporting the cloth; alternatively, the cloth can be made self-supporting through the wrapping or affixing of several cloth layers together. The burner element possesses a predetermined gas permeability adequate to avoid any significant backflash during the use of the burner. The gas permeability is selected to match the flow rate, composition and backpressure of the selected gas, and takes into account the insulative capacity of the fiber weave employed. The resulting burner construction is substantially more durable and resistant to damage during replacement or inspection than are burners having conventional ceramic elements, such as foams, felts, or the like.
