Improved design for enhanced productivity

Paul Wurth’s design of ignition hoods with a vertical burner arrangement enhances the sintering process. Compared to horizontal type ignition hoods, the vertical burner configuration has numerous advantages with a direct impact on plant productivity. Its compact design increases the effective sintering area and reduces specific fuel consumption. An enhanced and controlled cake temperature profile allows reducing the production of sinter fines, which has direct impact on the net production and solid fuel consumption. The strand production is further increased thanks to a greater available strand length in case of a brownfield replacement of a traditional hood, a reduced hood start-up time and reduced maintenance. Thermal efficiency is optimised, resulting in lower fuel consumption. Finally, a flexible burner configuration allows the use of blast furnace gas or coke oven gas as well as the use of pre-heated combustion air.
