Abstract

An EMPCO Unilance was installed on `D` electric arc furnace at Brymbo Steel Works (BSW), a division of United Engineering Steels (UES), in July 1987. The total cost of the installation was 122,679 pounds. Results indicate that the overall efficiency of electrical energy replacement was approximately 66% and the primary energy savings were 48,700 GJ/annum. Energy cost savings alone were approximately 67,000 pounds/annum, producing a simple payback of 1.8 years. The total cost savings to BSW including reduced melting time were in the region of 246,000 pounds/annum and produce a simple payback period of approximately six months. The Unilance is novel in that it combines the functions of an oxy-fuel burner and a non-consumable oxygen lance. The maximum rating of the burner is 18 MW but in this application the input was restricted to 10 MW. When used as a lance, oxygen rates up to 0.94 m{sup 3}/s (2,000 cfm) can be employed, although at BSM the rates were substantially less than this. Using a supplementary energy source to assist melting increases the delivered energy used at the furnace. However, because electrical energy is replaced by gas there is a reduction in the primary energy requirement, creating the potential for  More>>
