Summary:An optic-fibre sensor of flame fade-out in a single burner in corner or extreme wall-mounted burners of a high-power boiler, especially those fuelled with coal dust. It is characterised in that a measuring head (1) is positioned at the angle of 45 degrees - 90 degrees with respect to the longitudinal burner (2) axis, at the distance of the order of 1 m from the burner outlet, preferably in an inspection opening. It contains at least three optic fibres, mounted to ensure that the visual field cone (α1) of the first optic fibre covers the burner outlet, while the visual field cones (α2 , α3) of the next optic fibres are turned in direction of the inside of the burning chambers. The visual field cones of optic fibres allow flame zone characteristics to be observed. The visual field cones of neighbouring optic fibres overlap, and their symmetry axes are located in the same plane as the burner axis. The optic fibres are connected respectively to optoelectronic converters, which are connected through electric cables to a detector with a standard output.
