Monitoring And Control Of Air Pollution In Steel Manufacturing Industries

Abstract

Sponge iron is an intermediate product used for the manufacture of steel. Also referred to as Direct Reduced Iron (DRI) or Hot Briquetted Iron (HBI) in its compacted form, sponge iron is not a new route to steel production. For the production of primary iron, this route is recognized as an alternate route to blast furnace. Sponge iron is fed into the electric furnace for steel production or into foundries for the

manufacture of wrought iron.Sponge iron plants emit oxides of sulphur and nitrogen and hydrocarbons. These air pollutants are likely to increase the incidence of respiratory tract ailments, e.g., cough, phlegm, chronic bronchitis and also exacerbate asthmatic conditions.
