9)  GUIDELINES / CODE OF PRACTICE FOR POLLUTION PREVENTION FOR SPONGE IRON PLANTS (CPCB)

1. Air Pollution

Stack Emission from Kiln

       i. Adequately designed ESP or any other adequate air pollution control system/combination of system should be installed to achieve the prescribed stack emission standards.

 As installation and operation of Pollution Control Equipment for plants with less than 100 TPD capacity is not economically viable, therefore, it is recommended that plants with less than 100 TPD shall not be permitted in future.

Program for phasing out old plants having capacity less than 100 TPD shall be worked out by the State Pollution Control Board.

ii. All Pollution control equipment should be provided with separate electricity meter and totaliser for continuous recording of power consumption. The amperage of the ID fan should also be recorded continuously. Non-functioning of Pollution control equipment should be recorded in the same logbook along with reasons for not running the Pollution Control Equipment.

iii. The safety cap/emergency stack of rotary kiln type plant, which is generally installed above the After Burner Chamber (ABC) of feed end column should not be used for discharging untreated emission, bypassing the air pollution control device.

iv. In order to prevent bypassing of emissions through safety cap and non-operation of ESP or any other pollution control device, software controlled interlocking facility should be provided on the basis of real time data from the plant control system, to ensure stoppage of feed conveyor, so that, feed to the kiln would stop automatically, if safety cap of the rotary kiln is opened or ESP is not in operation. The system should be able to take care of multiple operating parameters and their inter relations to prevent any possibility of defeating the basic objective of the interlock. The system should be foolproof to prevent any kind of tempering. The software based interlocking system, proposed to be installed by industry should be get approved by the concerned State Pollution Control Board, for its adequacy, before installation by the industry.

v. Mechanical operated system for timely collection and removal of the flue dust generated in ESP or any other pollution control device shall be installed. /span>

Stack Emission from de-dusting units

All de-dusting units should be connected to a stack having a minimum stack height of 30 m. Sampling porthole and platform etc. shall be provided as per CPCB emission regulation to facilitate stack monitoring. De-dusting units can also be connected to ABC Chamber and finally emitted through common stack with kiln off-gas emissions.

Fugitive Emission

The measurement may be done, preferably on 8-hour basis with high volume sampler. However, depending upon the prevalent conditions at the site, the period of measurement can be reduced.

2. Effluent Discharge

  1. All efforts should be made to reuse and re-circulate the water and to maintain zero effluent discharge.

  2. Storm water / garland drain should be provided in the plant.

3. Noise Control

The industry should take measures to control the Noise Pollution so that the noise level standards already notified for Industrial area are complied.

4. Solid Waste Management

Char

Char should be mixed with coal or coal washery rejects and used as fuel in Fluidized Bed Combustion Boilers (FBC) for generation of power. The plants having capacity 200 TPD and above should install Fluidized Bed Combustion Boilers (FBC) for generation of power. Also the smaller capacity individual Sponge Iron Plants (Capacity upto 100 TPD) and operating in cluster can collectively install common Fluidized Bed Combustion Boilers (FBC) for power generation. The Sponge Iron Plant are free to explore other options / possibilities to use char for generation of power. Char can be sold to local entrepreneurs for making coal briquettes. It can also be mixed with coal fines, converted to briquettes and used in brick kilns.

Under no circumstances char should be disposed off in agricultural fields/other areas. Logbook for daily record, of Char production and usage must be maintained by the industry and the record shall be made available to officials of CPCB/SPCB/PCC during inspection.

Kiln Accretions

The kiln accretions are heavy solid lumps and can be used as sub- base material for road construction or landfill, after ascertaining the composition for its suitability and ensuring that it should not have any adverse environmental impact.

Gas Cleaning Plant (GCP)/Scrubber Sludge

The sludge should be compacted and suitably disposed off after ascertaining the composition for its suitability and ensuring that it should not have any adverse environmental impact.

Flue Dust / Fly ash

Flue dust is generated from air pollution control system i.e. ESP or any other air pollution control system installed with kiln. Secondary flue dust is also generated from Bag Filters or any other air pollution control equipment installed with Raw Material Handling, Coal Crusher, Cooler Discharge and Product house unit. The reuse/ recycling of the flue dust generated / collected may be explored and suitably implemented.

Fly ash brick manufacturing plant should be install for fly ash utilization. Fly ash can be utilized in cement making by Cement industry also.

Bottom Ash

Bottom ash may have objectionable metallic compounds, therefore should be stored in properly designed landfills as per CPCB guidelines to prevent leaching to the sub-soil and underground aquifer.

General

  1. Solid waste management program should be prepared with thrust on reuse and recycling. Solid waste disposal site should be earmarked within the plant premises. The storage site of solid waste should be scientifically designed keeping in view that the storage of solid waste should not have any adverse impact on the air quality or water regime, in any way.

  2. The various types of solid wastes generated should be stored separately as per CPCB guidelines so that it should not adversely affect the air quality, becoming air borne by wind or water regime during rainy season by flowing along with the storm water.

5. Raw Material handling and Preparation

  1. Unloading of coal by trucks or wagons should be carried out with proper care avoiding dropping of the materials from height. It is advisable to moist the material by sprinkling water while unloading.

  2. Crushing and screening operation should be carried out in enclosed area. Centralized de- dusting facility (collection hood and suction arrangements followed by de-dusting unit like bag filter or ESP or equally effective method or wet scrubber and finally discharge of emission through a stack) should be provided to control Fugitive Particulate Matter Emissions. The stack should confirm to the emission standards notified for de-dusting units. Water sprinkling arrangement should be provided at raw material heaps and on land around the crushing and screening units.

  3. Work area including the roads surrounding the plant shall be asphalted or concreted.

  1. Enclosure should be provided for belt conveyors and transfer points of belt conveyors.

The above enclosures shall be rigid and permanent (and not of flexible/ cloth type enclosures) and fitted with self- closing doors and close fitting entrances and exits, where conveyors pass through the enclosures. Flexible covers shall be installed at entry and exit of the conveyor to the enclosures, minimizing the gaps around the conveyors.

In the wet system, water sprays/ sprinklers shall be provided at the following strategic locations for dust suppression during raw material transfer:

    • Belt conveyor discharge/ transfer point

    • Crusher/screen discharge locations

6. Waste Heat Recovery Boiler (WHRB)

Sponge Iron Plants of capacity more than 100 TPD kilns shall use Waste Heat Recovery Boiler (WHRB) for generation of power.

7. Cooler Discharge and Product Separation Unit

Permanent and rigid enclosures shall be provided for belt conveyors and transfer points of belt conveyors. Dust extraction cum control system preferably bag filters or ESP to arrest product loss in cooler discharge and product separation area shall be installed.

8. Char based Power Plant

For plant having capacity of 200 TPD of cumulative kiln capacity, the power production through FBC boiler using char as a part of fuel, is a viable option. Power generation through FBC boiler using char as a part of fuel be implemented in a phased manner within 4 years of commissioning and targeting for 100% utilization of char.

Individual Sponge Iron Plants of capacity upto 100 TPD and located in cluster can install a common char based power plant collectively.

New Sponge Iron Plants

  1. No New Sponge Iron Plant will be commissioned without installation of Pollution control systems as stipulated in the Standards. The concerned State Pollution Control Board will accord consent to operate only after Physical verification of the adequacy of the Installed pollution control systems for meeting the standards and stipulated conditions in the consent to establish.

  1. All new kilns shall have the independent stack with the kiln or multi-flue stacks in case two or more kilns are joining the same stack for better dispersion of pollutants.

  2. Any entrepreneur having more than 2x100 TPD kiln may install WHRB for power generation, as it's a techno-economic viable option. For plants having capacity of 200 TPD or more, power generation using char in FBC Boiler as part of fuel is techno-economic viable option, therefore, new plants must install FBC boiler for power generation at the time of installation of the industry.

  3. Any new sponge iron plant being installed along with the other downstream facilities of converting the sponge iron into steel with/without further processing the steel should meet the target of 100% utilization of sensible heat of DR (Direct Reduction) Gas and Char for power generation. Wet scrubbing system for kiln off-gas treatment for such plants should not be opted.

10. General Guidelines
