Fast EAF Off-Gas Detection.

EAF steelmaking requires tight control of end-point carbon concentration and temperature for optimum product quality. The variable composition of scrap steel can make the control process difficult and often results in low-energy efficiency and/or high emissions due to sub-optimal combustion. Traditional off-gas monitors require significant on-site maintenance and calibration and do not provide a sufficiently fast response for operators to optimize the process. ZoloSCAN measures temperature, H2O, CO and CO2 in real-time, directly in the fourth hole duct using non-intrusive TDLAS technology. The ZoloSCAN delivers actionable, two-second updates of species concentrations and temperature that can be used to optimize post-combustion energy recovery and detect water leaks thereby improving EAF performance and safety.
