7. 7 Main Energy Forms used Electricity Fuels  Natural gas,  Coal,  Lignite and  Biomass fuels

8. 8 Major Energy Consuming Process Equipments Jet machines Drum machines Stenters Printing machines Loop machines Winding Machines Reeling Machines

9. 9 Major Energy Consuming Equipments Utilities Boiler Thermopac Pumps Air compressors Blowers Air conditioners Lighting etc.

10. 10 Energy Scenario Energy cost: 15 to 20% of the total production cost and varies as per the products manufactured. CMD: The connected load is less than or around 800 KVA in the majority of these textile mills, Steam demand: About 3 - 6 TPH depending on the production capacity of the plant. Electricity Consumption: The average electricity consumption for a single plant ranges from 12.00 to 24.00 lakh units per annum Fuel Consumption: (coal, lignite or biomass) is 5000 to 7000 tons per annum. The natural gas consumption is about 10 to 15 lakh SCM. Energy Bill: The annual energy bill varies from Rs.250 to 400 lakhs for a single plant.

11. 11 Fuel Cost  Electricity Rs. 5 per kWh  Bio mass Materials Rs.2500 per ton  Coal Rs.2500 per ton  Natural Gas Rs. 11.5 per SCM

12. 12 Possible Areas of EC and EE Energy Conservation Installing variable frequency drives for Jet machine pumps, ID and FD fans, Drum washers, oil circulation pumps, printing machines, air compressors will reduce energy consumption by about 20 to 25% Replace inefficient and local make pumps with new optimum sized and efficient pumps of KSB or Grundfos Recover sensible heat in drained hot water of Jet Machines and drum washers Install temperature control valves for all process equipments – Jet Machines, Drum machines, Stenters, Jigger machines etc Reduce hot air leaks from printing, stenter and loop machines Improve boiler efficiency, replace faulty and mismatch traps, avoid bypass of steam taps etc

13. 13 Energy Efficiency Replace new and energy efficient gas stenter machines and loop machines Install u tube jet machines with heat exchangers Co- generation for heat and power generation The monetary benefit is estimated as about Rs.25.00 to 40.00 lakhs per annum and the investment required for implementing the energy conservation measures is Rs.35.00 to 60.00 lakhs in various typical size of industries.

14. 14 Though there is potential for replacing inefficient equipments like stenters and loop machines, the investment is high. Energy Efficiency

15. 15 Issues and concerns for Implementation Involves high investment for technology change of various equipments and low returns Doesn’t have clarity on the savings achievable for the industry owners Interested in investment in low/medium cost energy efficiency measures, which have low payback periods of less than one year Financial Issues

16. 16 Technical Issues Lack of awareness on technologies available in the market Rely on local equipment suppliers Unskilled manpower and doesn’t have consciousness on energy and its control mechanism and equipments

17. 17 Other Issues Lack of space for implementing the measures Interested in implementation of successful technologies of the cluster Shortage of gas for adopting fuel switch measures Production loss may be evident during implementation

18. 18 Case Study Akashganga Processors Pvt. Ltd. Products Manufactured Synthetic Sarees Synthetic Dress Materials

19. 19 Main Energy Forms used Electricity Natural Gas Coal

20. 20 Annual Energy Bill Total: Rs. 289.67 lakhs

21. 21 Measures Identified  Heat Recovery from drained hot water of Jet Machines The monetary benefits are estimated as Rs. 12.23 lakhs per annum Reduces the fuel Consumption by 306 tons per annum The investment required for the insulated tank and heat exchanger is Rs. 6.00 lakhs Simple Pay back period is 6 months

22. 22  Replace Boiler Feed water pump Reduces the electricity consumption by 9300 kWh per annum Monetary savings is Rs.0.46 lakhs The investment required is Rs.0.50 lakhs Simple Payback period is 13 months

23. 23  Replace jet machine water circulation pumps Reduces the electricity consumption by 59,700 kWh Monetary savings is Rs.2.98 lakhs per annum The investment required for new pumps is Rs.5.00 lakhs Simple Payback period works out at 15 months

24. 24  Install Variable Frequency Drives for the Jet Machines Energy savings by implementing the measure is 53,200 kWh per annum Monetary savings is Rs. 2.7 lakhs per annum. The investment required for the VFD’s is Rs. 2.70 lakhs Simple Payback period works out at 12 months.

25. 25 Summary

26. 26 Tentative Schedule for Completion Dissemination Program : February 2010 Energy use and Technology Audit will be completed by March 2010 Cluster manual preparation by March 2010 DPR Preparations from April 2010 Local Service Providers Workshop June 2010 Other programs as decided by BEE
