Spanish technology supplier Sarralle Group tells Kallanish it has supplied a ladle preheating station capable of running entirely on green hydrogen to a Spanish steelmaker. This was the company’s pilot project.
“We replaced the existing burner that used natural gas as fuel with an oxy-combustion burner which can use 100% H2,” Sarralle explains. Using hydrogen, we achieve zero CO2 emissions in the ladle, as only water vapour is generated in the process.”
Electric arc furnaces, ladles and tundish heaters, continuous casting oxyfuel-cutting and the rolling mill reheating furnace are among the main steelmaking equipment with large natural gas consumptions that can be conditioned to work with the new burners, the company confirms.
