The decarbonisation of the steel industry requires significant technological and social advancements . The conversion of the equipment to both a new fuel and oxidizing agent results in significant changes which must be studied in detail .
heating equipment within the framework of hydrogenbased use , which is the most important step . The positive results obtained in the trial campaigns performed at the ladle preheater confirm that it is feasible to operate this heating equipment with 100 % hydrogen .
It is worth mentioning that the burner technology used for the ladle preheater is also applicable to other heating equipment such as Tundish preheaters and reheating furnaces . We have also adapted our Blue Efficient Arc Furnace to the newly developed H2 injector . Sarralle is already involved in the industrial implementation of these solutions .
Our focus is currently on working with a close customer to convert a reheating furnace into oxy-combustion burner technology , which will also be able to operate with both significant technological and natural gas and hydrogen . social advancements . The Reheating furnaces consume conversion of the equipment to around 75-80 % of natural gas both a new fuel and oxidizing of the entire steelmaking plant agent results in significant and are therefore responsible changes which must be for the largest portion of studied in detail . To overcome the facility ´ s CO 2 emissions . these challenges , in Sarralle Improving the efficiency of we have set ourselves the the reheating furnaces via strategic objective of making a oxy-combustion and taking a coordinated effort together with step further to operate them technology centers , experts in with 100 % hydrogen will hydrogen generation , and steel allow the almost complete companies . We strongly believe decarbonization of EAF-based that collaboration between plants . different entities is the key to the goal of making a net zero
The decarbonisation of
CO 2 emission steel industry a the steel industry requires reality in the near future .
No rest for the steel industry shareholders
HyInHeat is a European-funded project and one of the largest consortiums that are working on the topic of integrating hydrogen technologies industrially in the steel industry . It is based on the collaboration of 30 partners from 12 countries . Within this project , Sarralle is working on converting the combustion system of an existing industrial walking beam reheating furnace , from natural gas and air combustion to 100 % hydrogen oxy-combustion .
