The modelling of the furnace has been divided into two parts. On the one hand, a model describing the
physico-chemical processes which occur within the bed of solid. On the other hand, C.F.D.the topic of this
study, This model must include all the relevant physical phenomena occurring within the gaseous phase
(Turbulence, Chemical species transport and reaction, interaction between turbulence and combustion,
radiative heat transfer).
This work is a contribution to the numerical study of axisymmetric turbulent jets (burner CH4) reactive
fluids using (R.A.N.S) approach, in industrial furnace. The modelling of combustion is based on the
model of Magnussen. Turbulence effects are taken in account using the k-ε model .In the case of the
reactive jet, interesting result were obtained concerning the field of temperature, velocity and mass
fractions of the various species,noxious gas pollutant probleme source.
