Evaluation of ASD systems for electric arc furnace and argon oxygen decarburization refiner baghouse fans. Final report
Adjustable speed drive (ASD) control of the baghouse fans for Electric Arc Furnace (EAF) and Argon Oxygen Decarburization Vessel (AOD) can improve operations, reduce the degree of dust generation, and provide significant energy savings. The purpose of the project was to quantify the benefits, both in energy savings and other process improvements and to demonstrate the methodology of applying adjustable speed drives, to two baghouse fans from a system perspective. The report describes the approach to accomplishing the ASD equipment installation, the test procedure and methodology and provides the test results and economic return. The test results indicated that by using ASDs to control the extraction fan air flow for the EAF and AOD, the following benefits would be achieved on an annual basis: EAF annual energy savings, 267,929 kWh valued at $11,575; EAF dust reduction, overall, 2--3%; EAF dust reduction, during the flatbath period, 35%; and AOD annual energy savings, 1,443,078 kWh valued at $62,341.
