SUMMARY:Andritz green steel galvanizing furnace to avoid direct CO2 emissions
DESCRIPTION:This paper reports on a strategy of alternative heating solutions for a continuous galvanizing line in order to prevent any direct CO2 emissions, increase efficiency and production at the same time. 

This is possible by replacing common natural gas-fired radiant tubes with a new electrical heating system without modification of existing furnace setup, minimizing down-time and reducing the OPEX (lifetime increase and easier maintenance). The system – developed by ANDRITZ - is based on existing and reliable technologies and eliminates NOx emissions completely.

In addition, to electrical heating, an advanced type of hydrogen-ready burners was developed to replace the consumption of natural gas on direct fired furnaces – combined with decreasing respective CO2 emissions – potentially using green hydrogen. The performance of the new Green Hydrogen burners has been validated with CFD simulations, confirmed by laboratory tests with full hydrogen operation.

This internal development started 2 years ago has been confronted to customers, then validated during detail study in partnership with one of our long term and key clients. 
The study confirmed the expected results and even more, leading us to go further, building dedicated test furnaces and schedule industrial tests. The electrical test furnace is already in use to validate customer specific configurations in real operating conditions.
