  8. 8. Steam Distribution Diagram 10 ton/hr NG Boiler Main Steam Header 15 Kg/cm2 Soap Digesting Cosmetic Section Soap Manufacturing 6 ton/hr 2 ton/hr 2 ton/hr Condensate to Drain out
  9. 9. Schematic Diagram of Existing Boiler STEAM TO EXHAUST PROCESS GAS VENT Natural Circulation type water tube boiler STACK DEAERATOR 1983: Installation Rated capacity: 10 ton/hr Storage tank Rated pressure: 15 kg/cm2 Boiler Feed Water Pump BOILER PAKISTAN HMC BURNER WATER BLOW DOWN FROM MUD SOURCE DRUM FUEL BRINE CHEMICAL FEED SOFTENERS Deep well turbine pump
  10. 10. General Information About Existing Boiler  Existing Boiler Efficiency : 72% (Calculated)  Fuel Consumption rate : 906 Nm3/hr (NG)  Gas Consumption/ton of steam : 90.6 Nm3  Cost/ton of steam (Fuel) : BDT 530 : USD 7.6
  11. 11. Scope of Intervention STEAM TO EXHAUST GAS PROCESS VENT STACK Condensate DEAERATOR From Preheater Process Storage tank Boiler Feed Economizer Water Pump BOILER PAKISTAN HMC BURNER WATER SOURCE FUEL BLOW DOWN FROM MUD BRINE DRUM CHEMICAL FEED SOFTENERS Deep well turbine pump
  12. 12. Condition of Boiler after Intervention  Expected Boiler Efficiency : 81%  Expected Fuel Savings/year : 32,507 Nm3 (NG)  Annual equivalent cost savings : BDT 190462 : USD 2721 We observed that 9 ton/hr condensate is being drained  450000 kcal/hr heat can be recovered from the condensate recovery  Equivalent fuel savings : 478483 Nm3/year  Equivalent annual financial savings : BDT 2803912 : USD 40059
  13. 13. Recommendation  Maintain proper air-fuel ratio for combustion by controlling air damper.  Maintain regular tube cleaning and boiler feed water treatment.  Install air pre-heater and economizer.  Insulate all steam bare pipes and flanges.  Stop all steam leakages.  Ensure functioning of steam traps.
