Abstract
A flame detector device for use with boiler systems has been devised wherein a radiation sensitive means responds when energized by incident radiation of the selective frequency bandwidth to produce a signal indicative of the existence of a flame. A light pipe means includes a lens system for collecting incident radiation in a selected combustion zone of the flame and a flexible tube couples the radiation sensitive means and the lens system. A fiber optics bundle conveys the collected incident radiation from the lens system to the detector and is of an extruded high purity unclad quartz material thereof.
