We, in the Marine industry, are always enclosing our generators. In fact, most of the commercially available Marine Diesel generators come with enclosures. Obviously, if you are using a cooling method other than air-flow, this is possible. Rather than me re-design what we do here on e-mail might I suggest you go visit a marine (boating) supply store and ask them about sound-proofing material. Basically, build a box out of your desired material, make sure you have access panels where you need them, and line the box with a good heat resistant, sound deadening material and you're in business. It will help the noise level. However, some of the noise is going to be coming from your exhaust so make sure you have a good quality silencer installed as well. Keep in mind, back-pressure on the exhaust is critical (or should be taken into consideration). I don't know how your going to get that spec. from the Chinese for your application!
Good Luck and let us know how you make out. Dan P.S. Don't forget to run your air intake and exhaust outside of the enclosure! You will need to install you thermal transfer system (cooling system) outside of the enclosure as well. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, April 27, 2005 8:35 AM To: [EMAIL PROTECTED] Subject: Biofuel Digest, Vol 8, Issue 87 Send Biofuel mailing list submissions to [EMAIL PROTECTED] To subscribe or unsubscribe via the World Wide Web, visit http://wwia.org/mailman/listinfo/biofuel or, via email, send a message with subject or body 'help' to [EMAIL PROTECTED] You can reach the person managing the list at [EMAIL PROTECTED] When replying, please edit your Subject line so it is more specific than "Re: Contents of Biofuel digest..."

Clarity can take a little time (with biodiesel and in all human affairs, LOL!). If it's taking really a long time maybe there's a problem. Try heating it to 45-50 deg C and let it cool in a vented container. If it clouds up again on cooling, do it again. But you shouldn't have to do that, unless you're in a big hurry. We think good quality biodiesel is a golden yellow colour, and all our work confirms that, but there's quite a lot of controversy over it and I won't argue, to each his own. Using more catalyst might not be the answer if the reaction is not going to completion (or rather near enough to completion, it never reaches completion). Best to stick to your titration results, but do anything you can to try to improve the accuracy of your titration. More likely, if the reaction isn't going far enough it's because your mixing time is too short. I don't know what sort of agitation you're using, but 20 minutes is probably not long enough. A blender is that quick, but for single-stage base with our test-batch mini-processor, which uses an electric drill running at half-speed, we process one-litre test batches for an hour, and 130-135 deg F is a better processing temperature than 110-120 deg F. Check what Prof. Michael Allen has to say about how the process works: http://journeytoforever.org/biodiesel_processor8.html The Deepthort 100B - Batch Reactor for Making Methyl Esters as a Petro-diesel Substitute See "The Design of 'Deepthort'": "The third stage of the reaction is the slowest of the three and takes up to 40 minutes at 60 deg C (140 deg F)." Well worth a thorough read. More information here: Kinetics of Transesterification of Soybean Oil, H. Noureddini and D. Zhu, Journal of the American Oil Chemists' Society, Vol. 74, no. 11 (1997). This study investigates what actually happens during the transesterifcation process to produce biodiesel. The effect of variations in mixing intensity and temperature on the rate of reaction were studied at a constant ratio of alcohol to triglycerol and concentration of catalyst.

By the way, is it working at 1" or did you plumb it down to 3/4"? >(Maybe 4 hours total of run time with this new pump) Note: I need >a pump to outlet WVO lift to reactor intake is 5 feet. I don't know, but I think it had be able to do that too. These pumps were recommended by the people who who promote these reactors, and I've see quite a few photographs of them fitted and in use, so if they weren't even lifting it to the top I guess they'd have noticed. We pointed out some time ago that these pumps are not powerful enough to mix that volume of oil effectively in the given time (one hour), among other problems with those reactors, and hence the poor results, but it was half a year later before the Appleseed people starting hinting that maybe the pump wasn't strong enough. I'd say 25 gallons is the limit for the 1" clear water pump, unless you want to live with much longer processing times. But it should surely be able to lift the oil five feet. >Clearly I need to upgrade to pump the wvo to the reactor and also to >provide better circulating mixing and need to simply upgrade this >pump.

We've used a 1" Harbor Freight clear water pump for 72-litre batches (19 gal) for 18 months now, it's done hundreds of batches without any problems at all. Nice pump, hot oil no problem. I managed to drop the whole thing, pump down, when we moved house and the plastic casing on top broke. I patched it up with epoxy and it's fine, no damage to the pump itself.

My pleasure, I do hope it helps. Ethanol production is widespread in most rural areas, whether legal or not, so it's an existing knowledge base that can be added to for local fuel production needs. I'm looking forward to doing more work on this, and really looking forward to getting into ethanol production here this summer. As well as biogas production, as we discussed previously, hoping among other things to find out how best to utilise raw by-product from biodiesel production for methane production. A pressing problem for us, as our work with burning it as a winter heating fuel wasn't successful (though we solved the heating fuel problem another way, with low-conversion 5% methanol "biodiesel"). Progress isn't fast, but it's steady, we'll get there I'm sure. All of us. > Solid biofuel is poor rural man need , even India lack >research in this field, eventhough India has the simple and >solid biofuel social technology making use of cowdung , any >dried leaves , solar drying , amk possible removing animal waste from >big cites by self employed poor social enterprenuers, reusing the >wastes solids, instead of incinerating and land fill dumping , selling >this one as good poor man fuel of the low cost .But this simple >social self employed best technology is excluded by the >conventional technology of urbanization using gaseous biofuel is >pushed nowadays. Composting was put on a firm scientific footing in the 1920s by Sir Albert Howard in India, working with Indian peasants. (He said they were his professors. Pests and weeds were also his professors.) One of his aims was to extend the use of cowdung, because its use as solid fuel didn't leave enough for fertilising the soil. He found that properly made compost with only 20% cowdung content and the rest plant material was more effective than 100% cowdung (that's definitely true), so there was enough for both needs. Very good work! > Jelled biofuel with clean burning using novel products and >process can be as important project as that of BioD that appear >to have impact as social technology as the cow dung based solid >fuel technology. I agree. It has had very good results in some areas. I think it's different from BioD, they can fill different needs, different niches. They can be complementary, especially with your idea of integrated local biofuels projects. A missing piece in this puzzle is replacing kerosene for cooking stove fuel. Biodiesel works very well in pressure stoves (roarers), but not in wick stoves, unless they're specially designed. What would be more useful would be a wick stove, or any simple stove, that burns SVO, which will always be more easily available than biodiesel in rural areas. There are some ideas and some designs, but it's not there yet, needs more work. Another missing piece is what Robert was saying about Tom Reed's woodgas camp stoves - they work very well, but only because there's a battery to drive a fan for the primary air supply. I've been part of several intensive discussions with the stoves people on how to achieve this level of efficiency and control without a power source, and it's got nowhere, so far. I sort of gave up our work with woodgas stoves for the time being, hoping to find better answers for cooking with liquid biofuels rather than biomass. I have found some answers, much more to be done still. Not all the work with improved woodstoves is convincing. Often the target communities also aren't convinced. Some comparisons have found that the old three-stone woodfire can be as efficient or more efficient if it's done well. It might be a better idea to find the best fire builder in the valley and get him to give everyone else lessons on how to do it properly. There might also be a bigger need for good chimneys to take the smoke out than for improved woodstoves. Or ethanol gel, eh? Or a good vegoil stove design that a village blacksmith can produce. > Thanking once again on behalf all the developing countries , >students and teacher can do better social work with this new >products and good hope to have the great green future for the >needful based on the biomass fuel.

Presumably, because it's such a big engine. It's not, currently, sound proofed in any way but there is a baffle on the exhaust. It looks exactly like the picture on the first page of www.utterpower.com . I've seen baffles for the exhaust advertised on ebay. Would these make any significant difference to the noise? I could quite easily build a box around it with wood and line that with high temperature something or other to act as a sound proof. Do you know if this would work? What would be the best material to sound proof it with? I'm here in Oxfordshire in the UK. Slap bang in the middle of town. There is a cellar, however, part of which reaches under the pavement! If I can get the generator into this part of the cellar all aprox 200 KG of it or more and it cannot be heard on the street outside, when I run it, then I'll be quids in but if it can be heard then I've got to start thinking of ways to sound proof it so that I can sell it.
