Abstract: The Radiant Heat Baffle is a removable device which converts a conventional barbeque grill into a smoker by modifying the grill's heat transfer characteristics. The device blocks the primary radiant heat transfer pathway, extends the conductive heat transfer pathways and allows convection heating as the primary means of cooking. The device compartmentalizes the fuel, provides sufficient air flow to sustain combustion and the utility to conveniently add fuel during the cooking process.
