The steel industry is continuously looking for ways to improve energy efficiency and productivity. As reheat furnaces have a major impact on both, considerable work has been done in this area, and several alternative technologies have been developed. All of them, however, seem to have drawbacks as well as benefits. Low-cost solutions, such as oxygen enrichment, have technical limitations. Other alternatives, overcoming some of those limitations, become unreasonably complicated and expensive to install. In addition, most alternatives available to increase efficiency in reheat furnaces have environmental problems, such as increased emissions and high NO[sub x] formation. AGA Gas, Inc., in cooperation with The Timken Co., has developed a new burner system that gives maximum efficiency at a low investment cost. The first installation has been in operation in a production furnace since Jan. 1991. All important heating characteristics have been improved. At the same time, overall emissions, including NO[sub x], are substantially lower than for other burner systems. As a result, Timken has converted an additional furnace to the new technology and several more are being considered. AGA has also successfully installed the new system overseas.
