[biofuel] solar colector ( was Re: price of methanol )
My idea on a solar collector for BD involves running a heat eschanger. (disclaimer: I've been thinking about this for two years and haven't built it yet, so it's all in my head and needs to get taken with a greain of salt) The reason for the heat exchanger idea is that there are a few different points in the process which could benefit from heat and it seems to me that flexibility would be useful in what you can heat from your solar collector. (preheating before dewatering, then possibly preheating before making fuel (if you dewater on a different day) , heating wash water for less emulsion formation, or heating a wash tank to break an emulsion if it formed), or... all from one set of collecors. It of course means either having a heat exhchanger that you move in and out of a tank (I don' tlike this idea), or it means having a manifold with valves that can direct the heat eschang medium to different applications (more expensive parts-wise) which is what I want to do. The simplest system however is something like a batch water heater- ie a large solar box cooker, with a barrrel of water or a domestic water heater painted black encased in it. the water doesn't circulate in the simplest scenario, the whole batch gets heated all at once and used up all at once . This setup gets water quite hot, and it should work well for water or for oil. Do a search on the internet and you should be able to find a few deigns for this kind of solar batch water heater... mark --- In biofuel@yahoogroups.com, "Brent S" <[EMAIL PROTECTED]> wrote: > No pics or drawings of it, and I plan on changing the design a bit too.

No pics or drawings of it, and I plan on changing the design a bit too. And haven't figured out if I'll run the oil through it or run a heat exchanger off of it to the oil. Ill post what I can when I get it finished.

Re: [biofuel] solar colector ( was Re: price of methanol )
All great ideas. The simple one I made has a manifold at the top and bottom, with only 4 4 foot long abs pipes conecting them. I tested it one day just coverd with plastic and nothing attached. The result I got was encouraging, 70 deg in the bottom and 140 deg out the top. This can very easily be tweeked to get over 150 deg.

Re: [biofuel] solar colector ( was Re: price of methanol )
I used 3/4" CPVC washed it with plain rubbing alcohol and painted it flat black, mounted on a painted flat black sheet of OSB. I have a total of 175' of linear length. When the wind is not blowing, I am getting temperature of 160+, so I am in the process of adding a plexiglass [high temp] top on it. The bottom has R11 insulation in a 2"x4" frame, set so I can adjust the angle to the sun depending on the time of year. This is my hot water for my green house, but you are really giving me some ideas. Bright Blessings, Kim At 04:42 AM 5/21/2003 +, you wrote: >All great ideas.
