Biodiesel...Need to Heat Biodiesel?
914327
A fired heater will probably be the cheapest way.  You could try electric heaters (you can buy the elements from water heaters at appliance repair shops - they use 240V), but the electricity cost will probably be more than for the fuel (if you were thinking gas/petrol, maybe propane or natural gas will be cheaper).  I also don't know if I'd be comfortable putting electric elements in 3500 gallons of biodiesel - I've seen a few kitchen fires, and burning oil is never pleasant.\n\nYou could also consider solar heating - it would be cheaper in the long run, but any efficient installation would have to involve heating panels, piping, pumps, and a lot of water.  You could try painting your tank black, but that probably won't work very well unless you live in the desert or high plains.

just saying a heat absorber is not enough , for what purpose , this is science and accurate answer , cooper , aluminium , water , oil. ..etc , pls define more

>water evaporated at 100 degree Celsius.\n>oil remain for longer hour evaporated  (i.e) why people use oil to fry.

I would like to say yes but at this point I would have to say no. I worked at an ethanol pilot plant and anyone in the industry can tell you to break down starch in the corn you need what they call a jet cooker. This uses high pressure steam at appx 400-600F. There is no way in hell solar panels could heat water to this temperature effeciently and consistently. Plus a lot of ethanol plants run 24 hours a day and that right there pretty much shoots that plan in the ass. A good thought though. Ethanol will become more effecient once the enzyme industry catches up and can CHEAPLY use switchgrass as a fuel source.

Organic matter does not have to be heated to form petroleum.  Petroleum forms from compression AND heat.

To saponify with lye and water produces soap, with the glycerin still in it.\n\nTo saponify with lye water and ethanol produces pure glycerin, water and biodiesel fuel.

You can make your own diesel from used cooking oil.  Most fast food restaurants are glad to give it away because they would otherwise have to pay to have it halled off.  The set-up to convert it will cost between $200-$1000 depending on the method used and how much you want to be able to make at a time.  You can learn more about it here:

Make Magazine Online gives directions for doing a small batch at home; from there you can scale up.\n  \nhttp://www.makezine.com/03/biodiesel/      more at:\n \nhttp://www.google.com/custom?domains=makezine.com&sitesearch=makezine.com&q=makezine.com+biodiesel&cof=GALT%3A%23008000%3BGL%3A1%3BDIV%3A%23336699%3BVLC%3A663399%3BAH%3Acenter%3BBGC%3AFFFFFF%3BLBGC%3A336699%3BALC%3A0000FF%3BLC%3A0000FF%3BT%3A000000%3BGFNT%3A0000FF%3BGIMP%3A0000FF%3BFORID%3A1%3B&client=pub-1711976718738240&forid=1&ie=ISO-8859-1&oe=ISO-8859-1&hl=en&sa.x=11&sa.y=7

A synthetic gasoline product that we already have. Etyhenol (Spelling). I would also say that we could use some type of GeoThermal energy solution (like steam etc...)

Make a small scale ethanol still.  Lots of instructions on the net.  Kind of a hot topic with all the discussion of alternative fuels.

nope, just use alot of olive oil when frying! enjoy!!

Biodiesel is a vegetable (soy, rape seed, palm) or animal oil (lard or tallow) that has been chemically treated with alcohol (ethyl or methyl) to form an ester. \nA ton of biodiesel would need about 960 kg of oil. The rest of the mass would come from the alcohol.

Depending on the model most spas/hot-tubs will not heat without the water circulating.  The exception would be if the tub is equipped with a seperate circulation pump to move water through the heater.  Most spas have two-speed pumps- low speed to heat & filter and high speed for stronger jet action. Hot-spings does have a seperate circ pump to heat tub

Use Good Engine oil for the Best Speed for your PC. HA HA HA dont mind.

What type of oil fired plant are you refering to steam boiler/turbine or combustion turbine used in either the simple cycle or combined cycle mode. For a steam cycle, and without considering the practicality, one can add feedwater heaters, replace the turbine or install more efficient internals, increase steam pressure/temperature, better burners, more efficient motors, install variable speed drives on the bigger fan (forced draft, induced draft) motors, better insulation.\n\nNot sure how to do this.\n\nSome additional thoughts.\n\n>How clean do you keep the condenser?\n>Ditto for FW heaters. Do you calculate LMTD for the heaters?\n>Do your operators maintain all the parameters, e.g., SH temperature that affect heat rate? Do they have a HR parameter display, HR goals?\n>How clean is your turbine? When was it last opened? Washed?\n>Have you tested for seal leakage HP to IP?\n>Don't know your mode of operation, i.e., base, peaking, but do you use full arc or partial arc admission?\n>If your a peaker, and assuming you're not a UP, have you looked at variable pressure operation?\n>Peaking or cycling - have you optimized your start ups? Do you bottle up the boiler?\n>How clean is the boiler, especially, SH and RH passes?\nAdded:\n>GE and W used to offer high efficiency L-0 blades. How old is your unit? Do you have these blades installed?\n>Have you looked for hard particle erosion on your nozzle block and 1st stage blades?\n>Do you chemically clean the boiler? Do you have chordal thermocouples installed?\n>What condition is your air preheater in?

I believe the oil will burn before it boils.  I wouldn't try it.   Because nothing is quite so entertaining as a pot of boiling flaming olive oil!
