ABSTRACT:
A pre-mixed burner fired at or above atmospheric pressure by a gaseous fuel or a fuel that is liquid at ambient temperature or a liquid fuel completely evaporated prior to combustion comprises a mixer wherein the fuel, combustion air and a cooling fluid are blended prior to combustion downstream of a burner plate. The combustion forms a flame at or near the limit of flame stability. The ionization current which is a characteristic property of each flame is measured by two electrodes which transmit signals to a controller controlling the flow of at least one of the fluids flowing to the mixer by corresponding valve actuation for safe burner operation at or near the limit of flame stability.
