Hello,
i am new to the forum.
I am currently running B100 in a Toyotomi OM-22 vented heater. It works fine for a few days. Then I get carbon clogging the nozzle (not really a nozzle per se but a tube that drips fueal into the chamber. I have to clean the nozzle with a wire, and then it works well. It works even longer if I take out the flame rod and burn off any stuff on it with a flame. I think my problem may be two-fold.
I can see the flame in the pot, but I don;t think it is powerful enough to register for the flame rod, and I think that fuel may not be getting burned and accumulating in the bottom of the pot causing carbon build-up on the nozzle.
Does anyone have any suggestions?
I am thinking maybe a wider nozzle or a longer flame rod.

well you going to think Im nuts but search in here for Pinapple. Not sure if you have one or not in your present heater. If not adding one might enhance your burn and reduce chance of your nozzle issue

have you tried reducing the amount of fuel with a smaller nozzle, (and maybe increasing the pressure a bit)?

How do I go about increasing the pressure? This unit works with a gravity-fed nozzle. I would think that a smaller nozzle would clog. This is not a jet per se and the fuel is not atmized.

Also, thank you both for the replies. For some reason this forum is not showing up in my email. I will check more often.

One more thing. If I inject some methanol down into the pot I get a nice blue flame. I have mixed some in with my fuel (as Kero Klean) to see if this helps abate the soot and carbon build-up. I have not yet taken out the burn pot because there is an inordinate amount of sheet metal that needs to be removed (pretty much take apart the whole damn thing).
I think I may look into some sort of "pineapple." One of my friends is a copper worker. Maybe this would be a good material?

Tread wisely. While Pinapple may help.... watch temps. Just wondering if it will bring higher heats to parts of the heater not intended to reach higher temps.

ideas on how to make a Pinapple are in this forum already. Certainly not a copper thing if I recall right.

Yeah, I am not too comfortable with retro-fitting a brand new oil burner.
