SUMMARY:Off gas technology for EAF operations
DESCRIPTION:Since the introduction of Off Gas analysis instrumentation in the Electric Arc Furnace, different applications have been developed using this information to improve the process efficiency and safety. 

Using the CO, CO2, temperature, and flow of the gas, the AMI SmartFurnace modules for Chemical Energy optimization calculate the optimal setpoints of the EAF burners and lances. The chemical energy modules are complemented dynamic process models and algorithms for electrical energy providing an integral furnace control of the Oxygen, Natural Gas, and Carbon Injection, as well as continuous raw material feeding.

Using artificial intelligence, the Abnormal Water Vapor Detection module uses the gas temperature, flow, and water vapor content to identify unexpected sources of water in the off-gas which could pose a potential safety hazard, distinguishing it from the normal amount of water present in the furnace environment. 

Finally, the efforts to reduce emissions in the steel industry require accurate and reliable measurements of CO2. Understanding the influence of different conditions such as raw materials, melting profiles and practices, plays a major role in defining strategies to lower the environmental impact of the production.

 The latest implementations of this technology in plants with a wide range of raw materials, EAF mechanical characteristics, and production needs are described in this paper, and the achieved results.
