    Re: WVO Upflow Design ok?

    Had a good chat with the guy in the filter place in Welshpool this week. Seemed to know his stuff. I was buying replacement elements for my Delphi filter. He told me they were 10 Ám which was...

    Re: washing with heat

    Luckily for you I am a Chemist, unlike anyone else on this forum.

    Just heating the brew to remove the MeOH won't work - it will probably form an azeotrope (most alcohols do), but in any case the...

    Re: How do I plumb in a heat exchanger?

    No those sizes should be OK, particularly taking into account the viscosity reduction the extra heat will supply. This will be upstream of the other HE. The thing I like about it is that's nice and...

    Re: How do I plumb in a heat exchanger?

    It's for VO, because the first one (on the car when I got it), is for hot water. So the oil never gets hotter than 55 degrees, which is kind of OK, but it's a bit smokey when driving around town. I...

    Re: How do I plumb in a heat exchanger?

    Gotcha! I've finally worked the plumbing out - I didn't realise the heater loop as a completely different circuit from the coolant circuit - and in fact that's what the current HE is running off....

    Re: How do I plumb in a heat exchanger?

    Yes that's what I like about them too. And the oil is already coming in at 55 degrees, which is running fine in the car, I just want to reduce the thermal inertia of the system by fitting it upstream...

    Re: How do I plumb in a heat exchanger?

    The Frantz is a necessary part of my setup. Although it is (apparently) prone to cavitation it pulls out very fine particles and is much more use than an inline filter (every one I have seen has...

    How do I plumb in a heat exchanger?

    Following on from the other thread, my SVO is running well in my 1HDT motor, but because the HE was installed by the previous owner for showers, it's not the right unit, or in the right place for...

    Re: Pre Heating WVO before injector pump

    Change of plan - I've decided I'm going to install a second HE, before the CAV filter. What's the story with the plumbing? The coolant ports on the Helton unit are smaller than the other heater hoses...
  13. Re: My Ambient/ Room temperature Biodiesel Production

    FYI the other advantage of my method is that because of the very high catalyst concentration, a stirrer is not required. An el cheapo pool pump from EBay (set to recirculate) provides sufficient...
  14. Re: My Ambient/ Room temperature Biodiesel Production

    There isn't? Then why this?



    Did you? You didn't mention that above - you were talking about 23-47 degrees.

    So now all the threads on this site that talk about heaters can be removed and...
  15. Re: My Ambient/ Room temperature Biodiesel Production

    FYI my method can be used in the middle of winter with the temp at 8 degrees. The biggest problem I have is with the recirculating pump that does the mixing - at that temp it struggles with the...

    Re: Pre Heating WVO before injector pump

    Yes I'm well aware of that (believe it or not) - the point I was making is that at 55 deg is down on the flat part of the curve, and is much less viscous than RT oil. The oil in mine ATM is...
  17. Re: Common Rail and Veggie oil - Report on presentation by Alexander Noack of Greasen

    Well, I put it down to too much pressure being generated by the higher viscosity of the oil. It was actually a double whammy - I'd been running it OK on 50% WVO for months, and I foolishly decided to...
  18. Re: Common Rail and Veggie oil - Report on presentation by Alexander Noack of Greasen

    There are more things to think about with WVO on a common rail than just coking. I just destroyed the IP on my BT50 with a 70% WVO blend. It couldn't handle the viscoisity. But my Merc (OM613) ran...

    Re: Pre Heating WVO before injector pump

    Thanks for the info. I belong to the "if it ain't broke don't fix it" school of thought, and I've decided that since it's running fine as it is I'm going to leave it. I may revisit the idea next...

    Helton have a HE made specifically for biofuel (as well as the ones for showers). Is that the one you rtested?

    Re: Pre Heating WVO before injector pump

    You're referring to the Helton Unit. I had a look at it - it's pretty impressive - nice and compact. The question is do I get the single coil or twin coil unit? I reckon the single coil will do if...

    Re: Pre Heating WVO before injector pump

    Right, it's sorted - the problem was the Toyo filter. For some reason, it gums up as soon as the VO hits it, even after going through the Frantz. I know the oil isn't dirty because I've been running...

    Re: Pre Heating WVO before injector pump

    Thanks for the info. The problem your friend probably had with the Frantz is the size of the inlet and outlet ports, which are just too small for VO. Mine have been reamed out to 7 or 8mm ID.
    And as...

    Re: Pre Heating WVO before injector pump

    No I think the Frantz is pretty small because most of the volume is taken up by the filter element. The heat exchanger definitely has a larger volume – I reckon about a litre. And it's compounded by...

    Re: Pre Heating WVO before injector pump

    That's probably a little impractical as it would invovle a substantial amount of replumbing - a better idea is to fit a pair of 3-way solenoid valves to isolate the heat exchanger, which is the...
