Cooking kettle

摘要

A steam-jacketed kettle for cooking food includes a combustion chamber below the steam jacket. The combustion chamber is provided with an atmospheric gas burner for heating water in the steam jacket. The burner is disposed in an offset location at one side of the combustion chamber and a series of flue gas outlets are provided at the opposite side of the combustion chamber so that combustion gases tend to wash across the bottom wall of the steam jacket, for even heating. The flue gas outlets communicate with respective flue pipes that extend back through the steam jacket to a common flue gas collector, so that additional heat can be transferred from the gases in the flue pipes to the steam jacket.
