In the paper, a case of improvement in energy efficiency of a rollway-continuous furnace used for heat treatment in production of cold-drawn tubes as well as gas savings resulting from application of modern burners for radiant tubes was considered. For the investigated furnace, energy balance calculations were performed for the currently operating status as well as following replacement of burners for modern devices with better parameters of combustion and recuperation, which showed a significant reduction in fuel consumption. The burners ensure uniform temperature distribution along the radiant tube, stable operation, high energy efficiency also in high temperature furnaces and low emissions.
