A Comparative Study of Steel Furnaces and boilers Emissions with and without Emission Control System (ECS)

Abstract

In this study, emissions from boilers and steel furnaces with and without emission control systems (ECS), more especially wet scrubbers, were assessed. The concentrations of PM, SO₂, and NOₓ were determined using an isokinetic assembly for particulate matter (PM) monitoring and a flue gas analyzer for CO, NO_X and SO₂ monitoring. The efficacy of the wet scrubber in capturing airborne particles was demonstrated by the remarkable 70% reduction in PM emissions observed in the steel furnace findings. There was no discernible change in CO2 levels, and emissions of SOx and NOx were reduced by 15% and 16%, respectively, but CO emissions only dropped by 3.31%. With a reduction of 70.22% in SOx emissions, the wet scrubber proved to be the most efficient in lowering emissions of NOx (30.79%) and PM (27.75%) in the context of boilers. CO2 levels marginally increased while CO emissions declined by 17.75%. In general, the wet scrubber demonstrated significant efficacy in mitigating pollutants, including PM and SOx; however, its influence on CO and CO2 was restricted.
