RE: [Biofuel] Mother Earth News burners and biofuels
You've been here? That sounds good. Japan leaves you with good memories to cherish, doesn't it? Yes, I lived in Tsukuba city for a year between 1993 -94 and I was during the end of that year in Tokio during 2 weeks. I was granted with a scholarship by JICA for chemical technology in biotechnology and I worked extracting lipids from fungal mycelia that I brewed checking for bioactive compounds in the extracts (looking for anticancer drugs). I have really good menories I keep them in my heart, that period changed my way to appreciate the other cultures of many countries. I lived in a building with more than 200 people from many other differnt developing countries (we were called kenshuim). I visited Kyoto twice, a sight seen trip to many temples and religious gardens there and the second time I went there for a chemical symposium then I visited the crisantemun festival (the imperial flower of the japanese throne) at the old Kyoto Imperial Palace were I have seen the most loveliest sceneries made with Bonsay trees with small flowers and fruits!( totemo kiree desu :-) Here there is very few dust particles and artificial light is scarce that at night I can enjoy to watch a brilliant Milky Way with the naked eye sometimes looking for the famoust Southern Cross, I can see many more stars than in the heavily polluted japanese sky that only is clear after a snow storm. I remember I have seen the Mount Fuji from Tsukuba more than 100 Km away only after those storms. Best Regards.

And I finally figured out how to keep our house warm in the winter. LOL! Well, we get there in the end. With similar wonderful timing, last year at just this time I finished building our first MEN burner, the original design: http://journeytoforever.org/biofuel_library/ethanol_motherearth/me4.html Mother Earth: Waste Oil Heater Our one is here: http://journeytoforever.org/biofuel_library/ethanol_motherearth/me7.html Journey to Forever's Waste Oil Heater It worked really well with kerosene and with biodiesel, but it wouldn't burn biodiesel glycerine by-product, it quickly coked up. It did burn WVO, producing plenty of heat, but again it coked up quite quickly. Feasible, but too much cleaning involved. So I turned to Bruce Woodford's adaptation, which uses a forced air supply via a squirrel cage fan and a different burner design. Bruce says it reaches about 600-700 deg C at the stovetop, a lot hotter than the original design, which seemed hopeful. That's here: http://journeytoforever.org/biofuel_library/ethanol_motherearth/me6.html #mods Waste Oil Heater modifications Actually Bruce has produced a simpler design than this, I'll upload it soon with other new stuff. Great for waste motor oil, apparently - Bruce and his friends were unconcerned by the warnings last year from Richard Freudenberger, the original designer, that additives had raised the burning temperature of motor oil since the heater was designed and as a result it was no longer suitable for burning used motor oil. I did have some doubts, especially about the glycerine by-product - Michael Allen told me he thought it needed a burning temp of about 1,000 deg C and a residence time of 5 seconds. And perhaps pre-heating and atomisation as well, I thought. Only one way to find out... Nope. Strange - it didn't even like biodiesel, and just went out when I tried WVO, let alone glyc by-product. I stared at the thing resentfully and decided the burner was all wrong, no matter how well it might work with fossil fuels. So I substituted the burner from the original design, made out of a couple of frying pans and a perforated steel plate, fashioned a hood for the 2 air supply pipe to fit over it, and tried again. This worked very well with biodiesel, and much less well with WVO. So I made a 50-50 blend of WVO and biodiesel, and that worked just fine. I was testing the thing in the open backyard between the kitchen and the shed (workshop), it had been snowing and it was cold, but it warmed the whole yard up, amazing! I had to take my coat off. BUT, while we always have more WVO than we can use, plenty for winter heating fuel, I don't want to be making high-quality biodiesel all the time just to feed this thing. For one thing, the cost works out at not that much less than kerosene, which is about half the price of diesel fuel here, add the time and labour and it's not worth it. The main biodiesel cost component is of course the methanol. We get a good deal on it but it's still not cheap, and we can't get it any cheaper because there are restrictions here on how much you can store onsite. Anyway, at 20% methanol, a 50-50 mix uses 10% methanol, too much. So I made some 5% methanol biodiesel - single stage, the titration amount of KOH but only 5% meth. It dropped the glyc/FFA, but not as much as usual and it was sludgier than the usual by-product. It worked though - not something you want to put in your car, but it burned very well in the new burner. I burned it for a few hours, amazing amount of heat output, the lower half of the thing was red-hot. And no ash or sludge buildup in the burner. Right, good! At last. Maybe I can get that even lower, down to 4% meth or maybe less, but this is feasible anyway. We've been using a small woodstove in the kitchen, which works well, it made all the difference (and we have plenty of wood here), and we'd planned to put the WVO burner there, but it burns much too hot to have inside the house. Instead I'll have it outside, mounted inside a 200-litre oildrum (insulated
