Abstract

This work aims to
evaluate the reduce pollutant emission by steel reheating furnaces and
operating process of the diffusion flame industrials burners. The example
developed here is particularly interested in the influence of the air
preheating temperature on NOx emissions as well as the dynamic characteristics
and heat flow. The study was conducted on an industrial gas burners 250 kilowatt.
Numerical simulations are per formed using the computer code FLUENT, using the
turbulence standard k-ε model coupled to turbulent combustion ED (Eddy
Dissipation).The probability density function PDF model (6 species and
reactions 3) with a chemical equilibrium model. The results obtained for
different air preheat temperatures show that NOx emissions depend on the air
preheat temperature.
