The target of the project was to characterise a hot-air/oxygen fuel burner. Therefore, the proposers ran tests at a pilot furnace where the new type of burner was directly compared with conventional oxygen fuel burners. In a second stage of the project, a hot-air burner system was designed according to the requirements of a production electric arc furnace (EAF), tests of which demonstrated the performance under production conditions.

For the tests at the EAF of Badische Stahlwerke GmbH, a compact hot-air burner system was developed where hot-blast generation occurs without a regenerator. Hence, continuous burner operation is possible. This burner was successfully tested at the pilot furnace, was transferred to the EAF and was built in at the location of a conventional oxygen fuel burner. The tests at the EAF (a) showed the feasibility of a supplemental installation of this type, (b) proved the good thermal penetration behaviour of the hot-blast burner system, and (c) demonstrated its potential for prolonged operation times. From the latter point, the increase of the input of fossil energy into the EAF can be estimated to about a factor of two. .
