In physics, monochromatic light is electromagnetic radiation of a single frequency. In the physical sense, no source of electromagnetic radiation is purely monochromatic, since that would require a wave of infinite duration as a consequence of the Fourier transform's localization property (cf. spectral coherence).
A gas radiation calculation method and system in a methanol-coal mixed combustion process
This invention relates to the field of gas radiation calculation technology, providing a method and system for calculating gas radiation during methanol-coal blending. The method involves obtaining the monochromatic radiation absorption coefficients of each radiating gas component under basic operating parameters during the blending process, then using Planck's law to calculate the total emissivity of the mixed gas under different basic operating parameters during blending, establishing a benchmark database of gas radiation characteristics in methanol-coal blending; fitting the parameters of the mixed gas emissivity calculation model using the benchmark database; and calculating the gas radiation characteristics under any methanol-coal blending condition using a mixed gas emissivity calculation model with defined parameters, based on actual combustion conditions. This improves the accuracy of gas radiation characteristic calculation during blending and provides reliable theoretical support for the optimized design, operating parameter control, and energy saving and carbon reduction of methanol-coal blending systems.
