In pulverized-coal-fired furnaces, There are a great amount of burning coal particles with different burned-out. They are important medias for radiation heat transfer. The paper present the optical parameter of several kinds of different burned-exent of the same coal, calculated the absorption index of them. Also, using the index and MIE theory, calculated the important characteristics parameter-particle's absorption efficiency and scattering efficiency. For the measurement and numerical modelling of radiation hest transfer in combustion process, this work has practical value.
