Numerical simulation of pressure distribution in a walking-beam type reheating furnace

Abstract Numerical simulation of pressure distribution in a walking-beam reheating furnace was accomplished using FLUENT software. The effect of partition walls in the preheating zone on the flow field and pressure distribution in the reheating furnace was studied. The numerical results show that the partition walls in the preheating zone have an important influence on pressure distribution and temperature distribution in the reheating furnace. In order to improve the pressure distribution and the temperature uniformity in the reheating furnace, the partition walls in the preheating zone were retrofitted. After the partition walls retrofitting, the pressure distribution and the temperature distribution in the reheating furnace were improved. The heating efficiency of the reheating furnace was improved. Therefore, numerical results have great significance for improving pressure distribution and temperature distribution in the reheating furnace.
