Jindal Steel & Power Limited is deeply passionate about maintaining a clean and green environment in & around its plants. Air pollution is one of the major challenges that any company has to overcome in order to adhere to environmental norms. Keeping this in mind, JSPL follows a procedure of Total Productive Maintenance (TPM) for the prevention of Air Pollution. Every aspect of pollution generated due to plant activities is monitored in detail and adequate steps are taken to minimize it. The company has installed state-of-art pollution control devices suitable for the purpose of reducing atmospheric pollution. Real time check on performance of these devices is done through automated online analyzers such as Opacity Meters and Ambient Air Quality Monitoring Stations (AAQMS).
Some of the air pollution measures (unit wise) adopted by JSPL are as follows:
- In DRI Kilns, the dust Settling Chambers and ESPs (Electrostatic Precipitators) have been installed to control process emissions. Fugitive dust is controlled through multiple point suction hoods attached to bag filters. Dry fog dust suppression system is provided at required places.
- In Power plant, the flue gas from boilers is passed through ESP's where particulates are separated.
- In Coke Oven Plant, waste gases are burnt completely and the heat generated is used in Waste Heat Recovery Boilers (WHRB) for power generation.
- In Sinter Plant, a centralized de-dusting system with an Electrostatic Precipitator is installed for dust control in the raw material handling area. Additionally high capacity ESP also exists to control process emissions.
- In Blast Furnaces, the gases are cleaned through cyclone and two-stage venturi scrubber (Gas Cleaning Plant). Pulse jet and invertible bag filters have been installed to control emission from the stock house and cast house.
- In SAF, emission from the furnace is drawn in to high capacity dust extraction system, where particulates are trapped and treated gas is passed through chimney.
- In SMS (EAF & Ladle Furnace), the gases are sucked through the Fume Extraction System and taken to After Combustion Chamber for converting CO to CO2. Thereafter, the gases are passed through a cooling system, forced draft cooler, spark arrester to control coarse dust and subsequently through high efficiency bag filters to separate particulates.
- Other fugitive emissions: The fugitive emissions caused through non-process activities such as haul roads and stock yards are managed through good housekeeping practices and regular dust suppression through fixed and mobile sprinklers.
