  3. 3. Energy Crisis and Pakistan
  4. 4. Energy Crisis and Pakistan Energy is considered to be life line of any economy Energy is pivotal in running machinery in factories and industrial units In Pakistan During 2009-10, Energy supply witnessed a decline of 0.64 %. Pakistan needs around 15,000 to 20000 MW electricity per day and there is a shortfall of about 4000 to 9000 MW per day
  5. 5. Energy Crisis and Pakistan Resources of EnergyPetroleum products• In 2009-11, consumption of petroleum products was 35% of total share of energy.Natural Gas• Average production of natural gas is 4,048.76 million cubic feet per day and there is an increase of 1.56 percent.Coal• Coal is primarily being used in brick kiln and cement industries• Approximately 67 percent coal is imported because indigenous coal is not considered of good quality.
  6. 6. PAKISTAN “A DUMPING GROUND”
  7. 7. PAKISTAN “A DUMPING GROUND”• There is no proper waste collection system.• Waste is dumped on the streets.• There are no controlled sanitary landfill sites.• Citizens are not aware of the relationship between ways of disposing off waste and the resulting environmental and public health problems.Effects of Waste• Health Hazards• Ground water pollution• Air pollution
  8. 8. Typical Composition of Solid Waste in Pakistani Cities (%)
  9. 9. What is RDF?Refuse-derived fuel (RDF) is a fuel produced by shredding anddehydrating Solid waste (MSW) with a Waste Convertertechnology.Why RDF?RDF fuel pellets ranges from 75% to 85% of Coal used forelectric power generation.The emissions of RDF are less harmful than Coal.Coal contains approx. 70% carbon while RDF contains 52%carbon.Sulphur contents of RDF are lower than Coal.RDF typically produces 1 kWh for 15460 Btu (2.6 pounds ofRDF).
  10. 10. PROCESS FLOW DIAGRAM
  11. 11. PRODUCTION OF REFUSE DERIVED FUELSRDF can be produced by processing: MSW (Municipal Solid Waste) Industrial WasteEnd Markets of RDFRDF can be used: To produce electricity Alongside coal in Power Plants In Cement Kiln Industry

  13. 13. Primary Shredder
  14. 14. Primary Shredder Design of Shredder Motor Frame • Power = 3hp • Material = Mild steel • Rpm = 1400 • Grade = Astm 36 • Volts = 440Belt Shaft• Type = v-belt (B Type) • No. of shaft = 1• No. of belts = 2 • Material = mild steel• Length = 1524 mm • Length = 609.6 mm• Grove angle = 40 • Dia = 40mm • Rpm = 560
  15. 15. Pulley• No. of pulleys = 2• Material = Cast Iron Bearing• Type = B • No of bearings = 2• Dia of larger pulley = 254 mm • Type = ucp 208• RPM of larger pulley = 560 • Company = NTN• Dia of smaller pulley = 101.6 mm• RPM of smaller pulley = 1400 Blade • No. of blades = 8 • Material = Tool steel
