Utilizing hot EAF waste gases. A new SMS Siemag system for energy recovery from electric arc furnaces is a good example of joined-up thinking applied to energy and environment-saving plants. It works like this; the waste gas, with a temperature of 1,250° C, is channeled through a boiler system that converts the thermal energy into steam. There are plenty of ways you can use the steam. To augment your steam network, to drive turbines, or to power your air knife system. The steam is also a source of energy for waste water treatment or seawater desalination, or for driving the vacuum steam jet pumps in your vacuum degassing plant. That eliminates the need for a steam generator.
Converting waste gas into energy. Then there's gas recovery from converter steelworks. This involves capturing the energy-rich CO process gases generated in steel production and cooling them to around 1,800° C. Next, X-Melt® filter systems clean the dust out of the CO gas. Finally, the gas is stored in X-Melt® gas tanks, and can be used for instance to generate electricity in the steelworks. It’s perfectly possible to produce a volume of electricity that is equivalent to the annual consumption of a small town. As a steelworks operator, you can cut your costs by the same amount.
More than 40 percent savings with CSP®. As early as 1989, SMS Siemag launched a technological innovation on the market; continuous production of liquid steel directly into steel strip. CSP® stands for Compact Strip Production. It does away with the need to re-heat the steel slabs, a process that eats up energy. That saves up to 42 percent of the energy used in conventional production!
