Resumo

A mathematical model of radiative heat transfer in a disperse layer of opaque spherical particles chaotically distributed in space is suggested. The model is based on the approximation of the mean free path of photons. The expression is obtained for the layer effective emissivity dependent on the parameters characterizing the structure of a disperse layer and on the emissivity of the material of particles. A non-stationary problem of layer cooling is solved.
