Abstract
The combustion control system in the stee l heating furnace is optimized using laser absorption spectroscopy technology.The online analysis and detection instruments for O2 and CO furnace atmosphere are added in the homogenization section and heating section respectively,to achieve the transformation and upgrading of energy-saving technology in the heating furnace.Based on the heating process requirements of the heating furnace,the optimal excess air coefficient is calculated according to the residual oxygen concentration to achieve the best combustion state of the heating furnace,thereby saving gas consumption,reducing oxidation losses,improving heating efficiency,and achieving the goal of energy conservation and emission reduction.
