不同燃尽程度下粉煤燃烧微粒的光学特性和辐射特性

Optics and Radiation Characteristics of Pulverized-Coal Particles in the Difference Burn-out Degree

粉煤燃烧火焰中，辐射传热方式是最主要的传热方式，辐射媒体除三原子气体外，还有，诸如碳黑、未燃尽碳和飞灰这样的燃烧固体颗粒．本文介绍了对不同燃尽程度燃烧微粒的光学特性的研究，从而进一步得出这些燃烧微粒的辐射特性，为实际的粉煤燃烧辐射传热计算提供了较准确的依据．

Radiative heat transfer in the pulverized-coal fired flameis a main method of heat transfer, with the exception of threeatoms, radiative medium also includes some solid particlessuch as carbon black, unburn-out carbon and fly-ash.In the Paper, the investigation on optics characteristics ofpulverized-coal particles in the difference burn-out degree hadbeen presented, thereby, the rediative characteristics of theparticles had been got further more, it will provide an accuratefoundation for heat transfer calculation of real pulverized-Coalfired radiation.
