COAL VALUE-ADDITION INDUSTRIES For N.E.INDIA:Coal Pelletizing for FOR UTILIZATION OF COAL DUST & FINES �www.rade.co.in

1. FOR UTILIZATION OF COAL DUST & FINES

2. COAL OF N.E.INDIA
 Coal Mining Started in Assam in 1870.
 N.E. Region constitutes only 0.37% share of Indian
coal reserves.
 Coal is located in the States of Assam, Arunachal
Pradesh, Meghalaya & Nagaland.
 Is mostly sub-bituminous, semi anthracite Coal with
high calorific value between 6500-7500 k.cal/kg.
 Except for Coking units there are no Coal - Value
Addition based Industries in N.E.India.
 Coal is extensively used as Fuel by the Cement
Sector, Tea Gardens, Steel Rolling Mills.

3. SOME PROBLEMS OF N.E.INDIA COAL
 Diverse qualities from different locations & strata.
 Most Coals are very High in Sulphur.
 Other Coals are high in Caking index.
 Most are unsuitable for Metallurgical applications.
 Poor Mining practices generates high volume of Coal
Dust, Fines & Slurry.
 Inconsistent quality and sizes provides poor economy to
consumers.
 Consumers are located far from the mining areas.

4. PROBLEMS OF FINE COALS OR COAL DUST
 Difficulty in utilization.
 High loss as unburned particles or in stack emission.
 Prone to caking.
 Poor thermal yield.
 High loss during transportation.
 Contain high moisture / Difficult to dry.
 Fetch lower price than Lump Coal.
 Major cause of water and atmospheric pollution.

5. INTRODUCING COAL PELLETIZATION
The cost effective solution to myriad problems of Coal Dust.

6. BASIC FEATURES OF COAL PELLETS.
 Coal Dust is converted into hard solid lumps.
 Higher energy density & thermal yield.
 Easy to transport.
 Very low moisture < 2%.
 Market price at par or higher than Coal Lumps.
 Better combustion efficiency.
 Can be made from 3-60mm Coal Dust .
 Can utilize Coal Slurry in mixture.

7. Additional Features of Coal Pellets
 Pellet size can be changed as per requirement.
 Chemistry of the Pellets can be controlled.
 High Sulphur Coal can be Pelletized with sorbent.
 Higher Calorific Value if blended with Plastic waste.
 Coal can also be blended with Biomass like sawdust
to improve energy density.
 Coal pellets are resistant to rain & water.
 Not prone to spontaneous combustion.

8. BENEFITS OF COAL PELLETS
 Miners: Get better price for Coal Dust.
 Boiler Users: Complete Burnout of Coal without un-
burnt lumps or fines falling through the grating.
 Tea Gardens: No Coal caking on the Stoker grate.
 Sponge Iron Industry: Where Coal fines caking and
pollution is a major problem.
 Environment: Reduces Coal Dust, Slurry and Black
Smoke.

9. MANUFACTURING OF COAL PELLETS
 Low Investment in Machinery.
 Low Cost of Production.
 Low Manpower requirement.
 Flexible rate of Production from 5-35 Tons/Hr.
 Low Energy Requirement.
 Low Conversion Cost.
 Electricity can be generated by diesel Generator
running on Coal Gas.
