Abstract: Disclosed in the present invention is a visual monitoring method for cross-section temperature fields and radiation characteristics of boiler furnaces by combining radiation images and spectra. Image detectors can be directly inserted into observation holes of a boiler to acquire flame image data, so that when the detection system is applied to a power station boiler, extra holes are not required to be drilled, and therefore, there is no risk that the strength of a furnace wall of the boiler is reduced by drilling holes. According to cross-section temperature fields of a furnace measured by the detection system, the state of combustion in the furnace can be accurately judged, which can play an accurate and effective guiding role in boiler combustion control, and reduce the temperature deviation in each combustion area of the boiler so as to keep the boiler running smoothly, thereby improving the combustion efficiency of the boiler.

Abstract: A system for measuring temperature within a region to be tested includes a sensor means responsive to the temperature within the region for transmitting light energy along an optically-transmissive path and detector and amplifier means responsive to the light energy for producing an output signal which represents the intensity of the light energy. A signal processor electronically calculates a display signal from the output signal which represents the temperature within the test region. The signal processor performs this calcuation by solving Planck's equation, and a successive bisection technique is utilized to achieve extremely fine resolution of the temperature.

Abstract: A wavelength discriminator designed to collect broadband, multiple wavelength input energy, to isolate specific narrow bands of interest, and to image such narrow bands of interest upon closely spaced, separate detectors. This discriminator comprises optical devices (22, 18) for directing incoming radiant energy of a certain quality and involving a wide range of wavelengths through first (26a) and second (26b) wavelength selective reflectors separated by a medium that transmits the wavelengths of interest. The wavelength selective reflectors in accordance with this invention are in a non-parallel configuration and disposed in a double pass geometrical arrangement wherein energy of a certain wavelength reflected from the second wavelength selective reflector (26b) passes back through the first wavelength selective reflector (26a), with the energy from the first and second wavelength reflectors thereafter being directed onto respective detectors (32aand 32b). An embodiment involving a third wavelength selective reflector (26c) grouped with the first and second reflectors may be utilized, wherein energy of a different wavelength reflected from the third wavelength selective reflector passes back through both the second and first wavelength selective reflectors, with the selected wavelengths thereafter falling upon three separate detectors (32a, 32band 32c) of the array.
