摘要：

Oxyfuel technology is a promising option for carbon dioxide capture in greenfield as well as in retrofit power-plants. In the oxyfuel process the coal is burned in an atmosphere of pure oxygen and reduced flue gas. The resulting concentrations of CO2 and H2O in the flue gas exceed levels of conventional air firing by 3 to 4 times. This implies changes in radiant heat transfer. The present paper evaluates the behaviour of a two zone furnace heat transfer model under oxyfuel conditions. Results will show heat transfer tendencies for a typical oxyfuel flue gas composition.
