This work evaluated the performance of a combustion chamber operating with a self-recuperative burner at various atmospheric pressures by means of Computational Fluid Dynamics (CFD) simulation. The aim was to determine the effect of atmospheric pressure on the main variables of the combustion system through mathematical correlations and numerical simulations.
An analysis of the effect of burner location on the performance of a walking-beam type reheating furnace for an austenitizing process is presented in this work. Four configurations were evaluated, where the main difference was the position of four high-speed self-recuperative burners. The analysis was done through computational fluid dynamics (CFD) simulations, using a set of models suitable, and previously validated, to consider combustion, heat transfer, and billet heating, all in a 3D steady-state calculation.
The present study presents a numerical simulation of the effects of using self-recuperative burners on the performance of a walking-beam reheating furnace. The study was done using CFD (Computational Fluid Dynamics) simulations where a low computational cost method was implemented to simulate the billet heating as a steady state system. The preheating temperature of the air was defined as a function of the air mass flow and the flue gas temperature in each burner, using a UDF (User-Defined Function).
