  15. 2. Natural Draft Wood gas stove

  16. Main features • Operation type - batch • Operating time - 50 - 60 min. • Capacity - 600g • Can cook - 01KG of rice 300g sprats 250g of darl Mallum

  17. Biomass Product for the • Industry Industrial stove

  18. Features • Fuel : Fire wood • Capacity : 20 litre • Fire wood consumption rate : 04 kg/hr • No ash added to food • Portable • NO heat and smoke exposure to the operator • Heat controllable

  19. Applications Large scale cooking • Hotels • Canteens • Refugee Camps • Army Camps, etc. • Small & Medium Scale Industries • Milk industry • Kithul industry • Confectionary industry • Ayurvedic industry Existing Licensees 3 Nos

  20. 03 Technologies for domestic and cottage level industries • Need more New Licensees • Present License Charge - Rs.7500/- (Wood Gas Stove and Rice Cooker) , Rs.10,000 (Industrial Stove) • Annual Renewal Fee - Rs.1500 (Wood Gas Stove and Rice Cooker) , Rs.1000 (Industrial Stove)

  21. Chip wood feeding combustion chamber • As against log wood or Jungle wood burning • Can eventually feed Grilicidia pieces • Support sustainability • Even combustion • Field trials very encouraging Why Chip Wood

  22. End of Oil is already here. Coal is not far behind

  23. How is Sri Lanka Affected in a Scenario of Depleting Fuels? • Over dependence on fossil fuels • Drain on foreign exchange • We have no proven fossil fuel reserves • Exploration in progress, promises natural gas - commercially viability yet to be assess • Exploration and commercially viability of oil ? • Fuel Imports $ 3.0 Billion per Year and rising • Should we not think of Bio Mass

  24. Energy Options for Industry In a scenario of Depleting fossil fuels

  25. LOCAL ENERGY SCENARIO • Overall Scenario by Sector / Source Energy Consumption by Sector in 2007 (Total 8,233.0 TOE) Energy Consumption in Household, Commercial & others by Source in 2007 (Total 3,987.8 TOE) 25

  26. Energy Consumption in Industry by Source in 2007 (Total 2,111.0 TOE)

  27. We have Emphasized on Biomass • To maximize the use of indigenous resources • Reduce over dependence on fossil fuels • Reduce drain on foreign exchange • Adoption of eco friendly and sustainable practices • Encourage growing grilicidia & use for combustion • Carbon Neutral

  28. Why did we select Tea Sector • 524000 MT of annual Consumption of fuel wood • 70% of the total fuel wood consumption in Agro-Industrial sector is used by Tea Industry • Wood Logs are the main form of fuel wood • Logs from Rubber plantations • Logs from jungle fuel wood Hence Improving Efficiency of Combustion is a dire need

  29. Use of Biomass Energy in Tea Industry • Main Use • Generating hot air for drying tea • Other Uses • Withering Estimated total fuel wood consumed by Tea industry– 326,000 MT Rubber – 294,000 MT + Other 32,000 MT

  30. Switching from wood logs to wood chips

  31. How wood chips can improve the efficiency? 25 units - EXCESS 50 units - EXCESS Wood chips Wood log 100 units 100 units Combustion air Combustion air • Wood chips dries faster • With wood chips mechanized feeding possible

  32. Conventional system of manual feeding of Wood logs Improved mechanized system for feeding of wood chips at Deenside Tea Factory, Gampola

  33. ANIMATED IMPROVED SYSTEM MOTOR CONTROLLER FURNACE GRATE TEMPERATURE SENSOR TEA DRYER HEATEXCHANGER

  34. Wood logs Rubber wood chips Glricidia pieces

  35. CONTINOUS CHARGING OF FUEL WOOD CHIPS USING SCREW TYPE FEEDING SYSTEM Advantages 1). Could be retrofitted to existing system without any modifications. 2). At any time the system could be reverted back to conventional system 3). Charging of wood chips is required at 20 – 30 minutes intervals. 4). Controlled feeding of fuel wood can be achieved. 5). Specific fuel wood consumption can be maintained 0.7 0 1 kg of fuel wood chips per kg of dried tea. Cost of the equipment LKR. 800,000.00 Simple payback period < 1 yr

  36. FLEXIBLE TYPE SCREW FEEDING SYSTEM WITH ATWIN-SCREW DISTRIBUTION SYSTEM FOR FUEL WOOD CHIPS The new wood chips feeding system developed.

  37. Specific consumption of fuel wood in tea manufacturing Specific consumption of fuel wood (Fuel wood/Made Tea) is in the range of 1 – 2.3 kg fuel wood / kg Made tea Performance of pilot plant of wood chips feeding system in tea drying

  38. Improved biomass combustion system for Tea Industry • The second largest black tea producer in the world • Total employment for over one million people. • As a GHG, carbon dioxide (CO2) is the single largest contributor to climate change. • Fuel consumption by the tea sectors in India, Sri Lanka and Vietnam contribute to CO2 emissions annually by 1.352 millions, 0.708 and 0.085 million tons respectively. • Thus a need has arisen to promote and adopt Energy Efficient and Environmentally Sound Technologies (E3ST) in the tea sector. Hence the need for adaptation of this new technology by factory owners using either diesel or logwood for combustion

  39. The Next Step • 550 factories (approx.) uses logwood for combustion • 50 factories (approx.) uses diesel for combustion • 5 Nos. of licensees given the technology developed previously. Drier capacity 130 Kg/hr. • NERDC has now developed the technology to suit even higher capacity factories (270 Kg/hr. and above). • Need new/existing licensees to undertake conversion • From a national point of view this conversion is very necessary (very soon there will not be adequate quantities of logwood for tea drying)

  40. Existing Licensees • In 2006 given to 4 Nos. of licensees (Rs.25,000 initial payment and Rs.5000/- annual renewal fee ) M/s Puritas, Colombo M/s Metropolitan, Colombo M/s Helix, Colombo M/s Mavusta, Panadura • In 2010 given to M/S Glide, Boralasgamuwa (Rs.25,000 initial payment and Rs.5000/- annual renewal fee ) No records of conversions carried out

  41. Constraints Preventing Wide Spread Adoption Biomass Energy Technologies • Lack of awareness of the advantages and availability of technologies • Fear of shortage of biomass supplies • Lack of capital for conversion • Cost of energy not being a major component of the cost of production and thus not being considered a priority. • Lack of awareness on the requirement of sustainability.

  42. World Energy Outlook for Bio Mass 43 • Renewable Energy in focus • Green production attracting premium prices • Buyers demanding low carbon footprints for products

  43. As it is the Sri Lanka Situation If Gliricidia is grown can even reduce the Importation of Urea Fertilizer Saving on Fertilizer Subsidy
