Reducing atmospheric emissions under unfavorable weather conditions

Abstract

The West Siberian Metallurgical Combine developed a measuring system to reduce emissions during unfavorable weather conditions. Three regimes were developed which include a sequence of actions for personnel to detect and correct malfunctions of the dust catcher and coke-oven-gas collecting mains. Other measures more strictly monitor vehicular exhaust toxicity and prohibit unloading railcars containing blast-furnace top dust. In the second regime, measures of the first regime are augmented by increasing the oxygen content of the flue gases to 4% in the steam plant boilers which reduce carbon monoxide emissions by 17% and nitrogen oxide emissions by 47%. In the third regime, emissions are further reduced by reducing production.
