The apparatus includes a radiation gathering device having a narrow acceptance angle and mounted in a multiburner boiler to sight substantially across the discharge end of the burner nozzle. Radiation collected by the gathering device is transmitted by a fiber optic path to a radiation detecting device. The manner in which the apparatus is constructed and mounted insures that the radiation detecting device will be responsive only to the radiation resulting from the associated burner and not influenced by radiation from other burners in the boiler installation, or radiation from the boiler itself.
