Ever stricter legal requirements for emission controls, coupled with increasing economic pressures, have boosted demand for innovative and sustainable solutions that will lower costs while at the same time enhancing efficiency. This is especially true in energy-intensive processes such as steel production. In addition to the economic advantages, it also makes sense from an ecological perspective to recover energy from blast furnace gases.

Project description

Considerable volumes of energy-yielding gases are produced in the process of steel production (coke gas, furnace gas). The aim is for the Dillingen gas-fired power plant to utilize the energy from these gases. Evonik (formerly STEAG Saar Energy AG), Rogesa, and the Dillinger smelting plant have commissioned AE&E Inova with of the task of constructing a turnkey furnace-gas-fired power plant. The task comprises of complete design of the automation system, of the operator and monitoring interface, and of the external system link. INP International Projects is also supplying the main control technology (ABB Melody / 800xA), boiler protection (HIMA) and the furnace control system. Once constructed, this gas-fired power plant will cover the mayority of the Dillingen smelting plant’s energy requirements.
