Drip System / New Guy / Switch to Waste Motor Oil Topic
« on: October 21, 2011, 08:51:51 am »
Good Morining,
I'm new here but I notice there are very few posts in the "Drip" section, and the majority of discussion takes place under the topic of "Waste Motor Oil".
I know forums tend to have their own protocol, and I don't want to rock the boat but should I just post in the waste oil section? Seems the discussion there covers all different delivery systems.

That aside, I notice with coverting a fuel oil burner, the combustion air is generly preheated.
Is this necessary with a forced air drip system?
I was going to use outside air for combustion to avoid having  heated air from the room, going up the exhaust stack.
Is this a bad idea?
thanks,
rob jones

Drip System / Placement of Drip Valve
« on: October 21, 2011, 12:30:35 am »
Hi all
I'm building Bruce Woodfords modification of the MEN drip waste oil heater. I like the ease with which it appears the burner assembly can be cleaned.

I can only find a few photos and the drawn diagram of his air pipe and drip tube sizing. Does anyone know where add'l information can be found on his burner?

Also, I have a needle valve with a sight glass, [from McMaster-Carr] and was wondering if it would work better to have the metering valve before the oil is preheated or after.

My tank will be outside with a 3/4" pipe running into the bldg.  It "seems" the metering would be more consistant if it were after preheating as [after start up] the viscosity of the oil would be more constant and less affected by the [hopefully] rising temp.inside the building.

Thanks,
rob jones
