Re: [biofuels-biz] SVO versus BD
Hello Roger, I don't have personal experience with the oil in the burner of heating systems. I am occupied with the use of plant oil in a small family stove for cooking purposes. During the preparation of the burner project it was clear, that SVO can be used without any problems in heating systems, because it is well distributed by the injection system and the air stream. You should try it with a bucket and a steadily growing percentage of SVO. Up to 100 %. With our svo cooking stoves, we have more problems. We cannot use external energy to produce an air stream. The only help is to give some pressure into the oil reservoir (Petromax system). If you use the petromax system with plant oil, you get a cracking of the molecules within the pipes, which block them in a short time. This man from Hohenheim university found a method to get around this problem, and he shows a very nice plant oil burner (approx. 3 kW), which gives a blue, smokeless flame (like LPG). Perhaps you can contact Carl Bielenberg. He lives in your area (Vermont) and is very familiar with plant oil. His phone number is: 001 802 456 89 93.

Re: [biofuels-biz] SVO versus BD
Reinhard, you make a persuasive argument and have me rethinking my current biodiesel efforts. do you or others have experience with burning SVO in a home heating oil burner,for domestic heat and hot water? my other observation is that here in the USA our winters are usually much more severe that in Europe. (at least in the northeast states ,where i live) this would seem to complicate cold weather vehicle operation.thank you for sharing you insights regards, roger kurz ([EMAIL PROTECTED]) Yahoo!

[biofuels-biz] SVO versus BD
Albert Einstein often said: "Use the simplest thing that works, as long as it's the best thing." This in mind one should compare the two actual possibilities to use plant oil as fuel: 1) adaptation of the oil to the engine (bio-diesel, BD) 2) modification of the engine to run on pure plant oil (straight vegetable oil, svo) Plant oil is pure stored solar energy in its densiest form (9,2 kg /l). It contains only the elements carbon C, hydrogen H and oxygen O. In the simplest way it is produced only by grinding of seeds and pressing (ram presses, expellers) it. Purification by sedimentation and / or filtration: Can somebody imagine a simpler method of producing highly concentrated, environmentally friendly energy. In a short term planning, it is interesting to use biodiesel, because you can use the already existing car engines. But in a longer perspective, it is more interesting to adapt the engines to run on pure plant oil (SVO). And you have all the advantages of an decentralized fuekl production. And you dont need a chemical workshop to produce your own fuele at home. A ram press for about 200 $ and some plastc barrel is all you need. For the mean time, you can convert your diesel engines into plant oil engines (the still run on diesel). The conversion kits are not expensive, but they are a bit different for one engine or the other. (The Mercedes 123 engine doesn't have to be modified at all. You just run it with SVO. If its cold, you add some diesel. In Germany, the producer of the tractors for agriculture are already very interested to offer SVO-versions of their diersel engines to the farmers (Deutz, John Deere). So in a short future, probably the truck engine producers will do the same and later the car engine producers. Another important argument for the use of SVO instead of BD is the energy input for its production. With BD it is about 1/3, i.e. you need about 30% of the energy of 1 litre of BD to produce 1 litre of BD (in form of Merthanol or aethanol, chemicals, destillation/purification). For the production of SVO you need only about 15 % (12 % for agriculture, 3 % for oil extraction). If you use ecological advanced production methods, you can reduce these 12 % considerably. Ernst Schrimpff of the Tecnical College of Weihenstephan, Germany, listed 8 parameters to compare SVO with BD. Here his list (partly): see also the attachment or: http://jatropha.org/p-o-engines/svo-bd-characteristics.htm Plant oil (SVO) biodiesel (BD) 1) Physical characteristics: physical density0,90 - 0,92 0,88 viscosity 60 - 80 7 - 8 ignition point > 220 135 2) Chemical characteristics: phosphate mg/kg < 15< 15 sulphur mg/kg < 10< 10 Chem. reaction neutral, very low hygroscopic, solvent, fast reaction 3) Production: principle decentralized small central, big industrial units oil expellers chemical compounds needed - methanol, potassium hydroxyd energy input12 %29 % 5) Transport / storage no risk small risk 6) Environment biol. degradation very fast delayed danger to water no small human toxicity regularly notoxic (or small) material circuitcomplete difficult to realize 7) Social acceptability strategysmall, decentralizedbig, central logistics simple komplex transportation short distances long distances vulnerability small higher regional income highlow generation 8) Costs fuel production 0,25 - 0,40 0,45 - 0,60 US$ fuel prices 0,45 - 0,55 0,70 - 0,85 US$ Interesting links to this SVO - DB - discussion are: http://www.vegburner.co.uk http://www.pflanzenoel-motor.de (German) http://jatropha.org/p-o-engines/conversion-cars.htm http://elsbett.com/emotanfr.htm http://journeytoforever.org/biodiesel_svo.html Kind regards Reinhard Henning -- bagani GbR, Reinhard Henning, Rothkreuz 11, D-88138 Weissensberg, Germany Tel: ++49 8389 984129, Fax: 984128, e-mail: [EMAIL PROTECTED] internet: www.bagani.de [Non-text portions of this message have been removed] Yahoo!
