Concept

The LINDARC™ EVO off-gas analysis technology, with lasers installed on the fix duct, just after the secondary gap, uses the technique of “Multiplexed Tunable Diode Laser Absorption Spectroscopy” (WM-TDLAS) to obtain exact data of various gas species in the EAF off-gas system in real time. The LINDARC™ EVO is used to further optimize the EAF melting process, controlling fuel and oxygen post combustion by Q-MELT.

Benefits

SAFETY

• Real-time signal of H₂O will prevent explosions generated by water leaks.
• Real-time signal of CO will prevent explosions in the dust settling chamber or bag house.
• Possible set-up of gap / dumpers position.
• Real-time signal of CO will prevent excessive release of CO in the atmosphere.

OPTIMISATION

• High accuracy of CO and CO2 measured values.
• Fine tuning of burners settings (best ratio of CH₄ and O₂).
• High yield of CO combustion due to precise O₂ injection.
• High system functionality thanks to minimized maintenance design.
• Fast response time with real-time availability of measurement results (<2 sec.).
• All readings made on the real off-gas volume (no sampling, drying or filtering needed).
• Dynamic closed-loop control of burner and injection system by Q-MELT.

SAVINGS

• Maximum yield of oxygen requirements.
• Low maintenance cost (no filters, no driers installed).
• Reduced electric energy requirements as CO is combusted in the EAF shell.
