抄録

In order to investigate heat transfer in a carbon dioxide recovery furnace, radiative heat transfer was studied in a boiler furnace including water vapor, carbon soot and high concentration carbon dioxide. Numerical analysis was carried out using the Radiation Element Method by Ray Emission Model, REM², which can treat an arbitrary three-dimensional configuration, temperature distribution and participating media including anisotropic scattering particles. Heat flux on the boiler walls increases with increasing concentration of carbon dioxide, however, the concentration of more than 50% volume fraction reduces the flux slightly due to the greenhouse effect of participating gases. The heat generation rate or divergence of radiative flux decreases with increasing the concentration of carbon dioxide, which means an increase in flame temperature for a practical furnace. The soot in a flame increases the heat flux on the wall, however, relative effects of the carbon dioxide on the heat flux and heat gen eration rate decrease.
