Abstract
Disclosed is a vapor-jacketed cooking kettle having a compact, self-contained, gas-fired combustion system. The tiltable kettle includes a gas-fired cylindrical power burner which fires radially into a combustion chamber below a jet plate which in turn is closely spaced below the bottom wall of a water-containing jacket. Hot combustion gases produced by the burner heat and jet plate to temperatures at which it radiates large amounts of heat to the jacket wall. The hot gases also pass through holes in the plate to form high velocity jets which impinge on the jacket wall and transfer heat by convection. Heat transferred by the jet impingement and radiation vaporizes water in the jacket and the resulting steam cooks food products in the kettle. Thermal efficiencies of 70 percent or higher are achieved by the tilting kettle system.
