Heat Recovery and Burner Modification of an Industrial Tubular Furnace

Abstract:

The air preheater was installed on the furnace to decrease the exhaust gas temperature and heat the air to about 290°C. A radiant cylinder was added to the radiation section. Swirl flames were formed by adjusting the shape and the installation angles of the burner flame tubes. The radiation heat transfer was strengthened and the heat absorption was enhanced in the radiation section, while the temperature at the outlet of the furnace was decreased. Thus energy was saved by 16.7%.
