RE: [biofuel] Biodiesel conversion for boilers
Hi Myles, May I ask what is the cost of your Biodiesel/litre or gallon? Are you home brewing?

The seal leaking might not be a problem depending on the type of burner.

No problems over the past couple years so far---might be nozzle drip or seal leakage, but we haven't checked and haven't had any burning problems. In case this helps- -Myles Twete, Portland, Or.

Re: [biofuel] Biodiesel conversion for boilers
Kent, B-100 will run with no conversion in distillate fuel oil and waste motor oil fired boilers. Todd Swearingen - Original Message - From: essentialkent [EMAIL PROTECTED] To: biofuel@yahoogroups.com Sent: Monday, June 30, 2003 8:20 PM Subject: [biofuel] Biodiesel conversion for boilers Hello, Just joined the group. My name is Kent McKay, and I am a distiller of organic essential oils in Costa RIca and Canada. I also build stills for other eco based projects and have been asked to put a quote together for a Mayan community still in Guatemala. They are interested in using biodiesel for the boiler. Guatemala apparently has quite a movement in biodiesel. I have some exposure to the use of biodiesel as I work with permaculture projects and have seen different bus conversions, but no experience with boiler conversions. Have searched the archives a bit here, and have seen some discussions back in 2001 in the group. Searching the web has been somewhat frustrating on an info level for boilers. Does anyone have knowledge of a company I could contact for professional conversion, or any boiler manufactuers that are now able to provide this conversion with their equipment?? Any leads would be most helpful and appreciated to try and get this worthwile project of the ground.
