TWINGHY: advancing the use of hydrogen burners for greener performance
The TWINGHY project was launched in the CELSA Barcelona plant in Spain and aims to demonstrate an optimized heat transfer process based on hybrid burners in reheating furnaces. It will allow progressively decarbonize the reheating process through an increase of hydrogen in combination with oxygen by monitoring and controlling it through a digital twin.
With the ultimate goal of reducing emissions and increasing energy efficiency within the steel industry, this project involves testing and optimizing hybrid burners in real-world settings, developing new control systems and monitoring techniques to ensure a safe, efficient operation.
Testing will take place on the existing Stein Digit@l Furnace®, installed by Fives at CELSA Barcelona plant in 2009. This is a walking beam furnace of 180 tons per hour capacity designated for the production of different merchant bars in the construction industry.
Two types of hybrid burners (natural gas-hydrogen) will be developed and tested: one based on air-combustion and the other on oxy-combustion. Fives will be providing its thermal reheating expertise to test the hybrid burners by using hydrogen as a partial replacement for natural gas.
