The aim of the project is to reduce the plant’s operative costs in order to increase competitiveness. The project mainly consists in redesigning the combustion equipment, which presently runs with 100 percent natural gas, by introducing the possibility of also combusting blast furnace gas. The new combustion equipment is to provide the flexibility to use a mixed fuel of variable percentages of natural gas and blast furnace gas, with the latter being preheated by a new recuperator. Thus, the new system will be able to save approximately 80 percent of current natural gas consumption.
