Modeling of Radiation Heat Transfer in a Boiler Furnace

Research output: Contribution to journalArticleScientificpeer-review


For prediction of incident radiative heat fluxes on the furnace walls of a boiler,
one of the most accurate radiation models, the zone method of analysis, has been
employed to analyze radiative heat transfer in the freeboard of large pulverized
fuel utility boilers. By using this model, the behavior of the temperature and heat
flux within the furnace and on the heat surfaces is investigated. The existing
formula for the velocity field of a turbulent jet exit from the burner orifice is used
to model the velocity field of the combusted fuel from the burner. Comparing
model’s predictions with experimental measured radiative fluxes on the walls
showed the accuracy of the method.
