Heating process of a continuous furnace, in particular for steel products and continuous furnace

摘要

Heating process for steel products, in a continuous charging type furnace where products (1) flow from a charging end (2) to an end (3) for drawing the charge; the furnace comprises a heating zone (4) with air/fuel burners (41) possibly doped with oxygen, with air combustion fumes released near the end (3); a recovery zone of the fumes (5) is located in that area; the process is characterized by the introduction of gaseous combustive material with the fumes, and the introduction of possibly doped oxygen gas upstream of the most upstream air/fuel burner, the combustive material is burnt rising the temperature in the recovery zone. An Independent claim is also included for a heating furnace.
