7. CONCLUSION

Superheating the blast air using plasma torch technology offers an opportunity to reduce coke consumption below today’s best practices with oxygen enriched blast and coal injection. The plasma technology can be introduced in a staged manner to allow for the required engineering developments to be completed and optimized.

The financial payback is attractive, with payback of about 2.5 years, and this can be achieved for each stage of the technology implementation. Engineering design work is needed to develop the best way to implement the newer plasma torches available from Alter NRG, including an ultra high temperature hot blast system. With a focused development program, these engineering challenges can be overcome.
