Modeling of Radiation Heat Transfer in a Boiler Furnace

12/9/2007 · 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 …
