Abstract
In a gas-fired stove or oven, gas is burned in a porous ceramic surface combustion burner which generates selective emissive radiation in a narrow band. The high temperature surface of the burner includes a narrow band quantum emitting substance such as rare earth metal oxide. Relatively shorter wavelength radiation from this quantum emitting surface illuminates process targets having an absorption spectrum nearly matched to the emission spectrum of the burner surface, for a variety of applications such as cooking. The selected emission may be passed through a glass top stove to heat a pot with an absorptive bottom or may pass on through a glass pot to heat the food directly.
Claims29
A gas fired stove comprising:
- a gas combustion burner including an emitting material that emits radiation in a narrow wavelength band;
- means for supplying gas and air to the burner for combustion and heating of the emitting material to a temperature where narrow band emission occurs;
- and
- a cooking top adjacent to the burner transparent to at least a band of radiation corresponding to the narrow band of radiation emitted by the burner.
A gas fired stove comprising:
- a porous matrix burner including an emitting material on at least its outer surface that emits radiation in a narrow wavelength band;
- means for supplying gas and air to the porous matrix burner for combustion in the porous matrix;
- and
- a cooking top adjacent to the burner transparent to at least a band of radiation corresponding to the narrow band of radiation emitted by the burner.
A gas fired stove comprising:
- a gas combustion burner including an emitting material that emits radiation in a narrow wavelength band;
- means for supplying gas and air to the burner for combustion and heating of the emitting material to a temperature where narrow band emission occurs;
- a cooking vessel having at least a portion that is transparent to the narrow band of radiation emitted by the burner;
- and
- means for supporting the cooking vessel adjacent to the burner.
A gas fired stove comprising:
- a gas combustion burner that emits largely black body radiation;
- filter means adjacent to the burner for transmitting a selected wavelength band of radiation from the burner and reflecting other wavelengths of radiation from the burner;
- means for supplying gas and air to the burner for combustion and heating of the burner;
- and
- a cooking top adjacent to the burner which is transparent to at least a band of radiation corresponding to the band of radiation passed by the filter.
