Thank you very much Balaji < You are welcome. We have lot of cocunut husk hsk here all wasted . we suerly need you help for this project development Can you give us some details about the low cost brick or ceramic gasificatio units for rural areas . <Coconut husk by itself has very low bulk density and high moisture. To meet dryness needs of the process (<10%), you need to firstly dry the biomass with <waste heat from the exhaust of the engine generators/combustor at zero thermal energy cost. To meet denstiy requirements, you can blend coconut husk with <other waste biomass such as wood, coconut shell and fronds. We had tried out equal measures of coconut husk, shell and fronds and this gasified very well. < Considering your social orientation with emphasis on employment and income generation in Braziil's rural areas, you can derive coir a value added product from <coconut husk. After rettting the biomass in water, the fibres are separated and twisted into hardy ropes which do not easily biodegrade even in the presence of <water, owing to high lignin content. Remember the coir ropes in our village wells, which last ages? <The residual powdery coir pith left from coir manufacture is very light weight and contains a lot of moisture. This will need to be binderless briquetted after <drying and can also be gasified. <We use a lot of insulation material both as themal and chemical barriers (not exactly ceramics) to protect the steel shell of the reactor core (~1600 deg C ) I <remember IISc had tried to develop a low cost ceramic model in the early nineties, but it was not rugged enough for long term operation. In fact, if you look for <extended and trouble free plant operation and life, low cost is at a discount. No pun intended :-) What about any new news from IIsc gasifaction adopted to rural areas. <The first gasifiers installed in Hosahalli and Hanumanthanagara villages in Karnataka are still functional. a 20 kWe duel fuel system is installed in your own <Univeristy of Sao Paulo. Another 25 kWe systems is installed in Butachaques island in Chile and services the need of the remote red Indian community there. < Only 44% of rural households in India are electrified. The Ministry of Power in India has an ambitious scheme of providing power for all the remaining 78 million <rural housholds in over 100, 000 villages in the next 5 years. We hope to contribute our mite to this effort. 100% gas engine generators in the 10. 20, 30, 40 kW <range are now under test <http://powermin.nic.in/whats_new/pdf/Rajiv_gandhi.pdf Thanking you yours sincerly P.V.Pannirselvam < Regards <balaji _______________________________________________ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/
