摘要: In a heating appliance employing radiant burner, method and apparatus for setting the ratio of gaseous fuel to air supplied burner desired value. With flow rate held constant, is controlled maintain fuel-to-air at The invention uses sensor that measures intensity radiation emitted by burner. A control device compares measured reference regulates such equal intensity. emits when it burning combustible gas supply containing ratio, so regulating cause emit intensity, will be
