Resumo

Development work on the use of plasma torches in blast furnace ironmaking was completed in the 1980s. The technology developers planned to reduce blast furnace coke consumption using electrical energy and large scale coal injection through the tuyeres. Since this time, Westinghouse Plasma Corporation has improved torch reliability with industrial experience in solid-waste-to-energy facilities, as well as metallurgical applications. As coke makes up one-third of the hot metal cost, savings efforts frequently seek to lower coke consumption by increasing process efficiency or replacing coke with cheaper fuels. Alter NRG and Hatch assessed the merits of using plasma torch technology to superheat the hot blast. Coke rate savings, electrical purchase requirements, and a financial analysis to implement the torches are presented.
