Furnace rebuild increases throughput
An
Eurotherm product story

The Digital Firing technique allows the profile within the furnace to be tailored to match the optimum heating curve and furnace profile for each product.
A walking beam furnace rebuild, incorporating a Stein Heurtey DigitalFurnace solution with a control system implemented by Eurotherm, has increased throughput and delivered improved energy efficiency while reducing emissions for Corus in its Port Talbot plant.
Corus needed to replace an existing walking beam furnace installation with one that will provide increased throughput and availability.
Improving energy efficiency and the ability to burn dual fuels, with a reduction in Nox and CO2 emissions were also an integral part of the specification.
Working together with the furnace manufacturer Stein Heurtey, Eurotherm was able to use Stein Heurtey's knowledge of the process and furnace design, together with Eurotherm's expertise in control system design and implementation, to deliver a furnace and control solution that would achieve the requirements Corus had identified.
These improvements were achieved following the installation of the new Stein Heurtey patented DigitalFurnace configuration of burners with the Eurotherm supplied control system, using a concept patented, by Stein Heurtey, Digital Firing technique.
The Digital Firing technique allows the profile within the furnace to be tailored to match the optimum heating curve and furnace profile for each product.
This ensures that the minimum energy for the heating phases is consumed and the product cycle is consequently reduced to its minimum.
