摘要
结合火焰辐射传递方程 ,推导出辐射强度随投影路径衰减的控制方程。炉内弥散介质的辐射特性根据Mie理论进行计算。将火焰断面网格化之后 ,运用代数重建技术 (Al gebraicReconstructionTechnique)对离散方程进行迭代求解。
In this paper, based on flame radiative transfer equation, the control equation of the radiation intensity which decays with projective paths is deduced. Radiative extinction coefficient of scattering medium in the boiler carried out according to Mie theory . After dividing a flame section into M×N grids, temperature distribution will be solved by iterating to discrete equations using Algebraic Reconstruction technique(ART). Experiment research is proceeding on a power plant boiler by using this method.
