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.
