Siemens Installing Energy, Carbon Saving Steel Furnace for Tyasa; First Demand Response Customer Goes Live

Siemens is installing an energy-saving electric arc furnace for turning scrap iron into steel at a plant owned by steel manufacturer Tyasa in Ixtaczoquitlan, in the Mexican state of Veracruz.

The Simetal EAF Quantum furnace recovers energy from hot exhaust gas, cutting costs by around 20 percent and reducing CO2 emissions by up to 30 percent, Siemens says.

Electric arc systems are particularly well suited for making steel from scrap iron, according to Siemens. The electric arc heats the scrap metal to over 1,500 degrees Celsius so that it melts. However, the process consumes vast amounts of electricity, produces lots of carbon dioxide, and can lead to fluctuations in the stability of the power grid, the company says.

The Simetal EAF Quantum uses the exhaust gasses to preheat the scrap steel to over 600 degrees Celsius prior to melting, reducing the strain on the furnace and lessening the repercussions for the power grid, Siemens says.

The Tyasa facility is scheduled to be completed by mid-2013.

In other Siemens news, the company’s smart grid division has announced that Wabash Valley Power Association is the first customer to go live with the Siemens Demand Response Management System. WVPA is a non-profit generation and transmission organization that meets the power supply needs of electric distribution cooperatives serving 750,000 people in Indiana, Illinois, Missouri and Ohio.

Siemens DRMS provides the association with the ability to calculate baselines, shed load across multiple distribution systems using several different demand response programs, and automate customer billing and settlement without processes that previously required multiple spreadsheets for calculation, Siemens says.
