  • Integrated spectral flame monitor
    Patent number: 5488355
    Abstract: An oil flame monitoring system has an ultraviolet flame detector 1 and an infra red Flicker flame detector 2. The UV flame detector views a region 11 of the flame 5 known as the primary combustion zone which is situated about 1 to 2 metres downstream of a fuel atomizer 4. The IR Flicker flame detector 2 views a region 3 of the flame 5 inside the fuel oil spray just downstream of the fuel atomizer 4. A programmable logic controller processes the outputs of the two detectors 1, 2 and provides information about the position of the flame front and the quality of the flame.
