Abstract
In today’s competitive market, it is of utmost importance for EAF steel makers to perfect their processes in order to reduce operating costs and improve the safety and reliability of their equipment. The innovative LINDARC™ technology, with laser units installed on the fixed duct, just after the combustion gap, uses the technique of “Tuneable Diode Laser Absorption Spectroscopy” (TDLAS). It performs real-time off-gas emissions measurements of CO, O2, H2O and temperature of off-gas. A closed-loop operation is in place for dynamic control of the chemical energy package and dedicated postcombustors to perform CO, H2 and CH4 combustion into the EAF furnace shell. The system has, so far, proven its reliability, resulting in a maintenance free operation, and the optimization of carbonaceous fuels combustion with subsequent electric energy, oxygen and natural gas reduction.This paper describes LINDARC TDLAS laser technology, the laser on-site installations, the post-combustion injectors, the closedloop- control strategy and future developments of the system.
