摘要	Compared with non-gray model, equivalent gray model has equal calculation accuracy but much higher computing speed. To solve the existing problems of the equivalent gray method, sole ternary model was developed. In the model, coupling solving process of energy balance equations is omitted and the model zone is real closed. Meanwhile, the full furnace temperature and heat flow calculations are avoided, which makes it easier to find the relationship between the equivalent gray gas radiation characteristic parameter and the initial conditions. The radiation characteristic parameter was calculated with different temperature combinations, different model zone sizes and different partial pressures of absorbent gas. The results show the similar variations in the absorption coefficient and emissivity for the equivalent gray model, which both decrease with the increase of the gas temperature and the surface temperature (especially the former one) as well as the model zone size while increase with the increase of the partial pressure of absorbent gas.
