cold oil ine

jrc2905

any sugestions for dealing with a cold oil line, the oil coming in is 25 degrees. Is the use of heat tape a viable option. I have good oil flow but the burner loses oil flow after a miute or two. The oil company claims they treated the tank but I am no so sure after talking with them. I put two bottles of hot in the tank and 24 hrs later I still have the problem. This is a two pipe system. I am now running the system off a 5 gal bucket anf it works fine.

change

to a one pipe and a tigerloop! What shape are your filter and screen in. I would change the filter cartridge and at least clean the pump screen. At that temp there are a few waxy particles flowing thru the line and may be clogging the filter materials.

oil line heaters

i've seen them but never used a nozzle line heater that mounts to the burner noz assembly but has the oil co blew back and hand pumped your lines and has any one checked the vacume on the pump and the pump pressure also have they ran the burner with jet line un hooked to see if your getting constant fuel flow through the pump with no air or irregular oil flow also has someone changed the filter and pump sreen is your tank above grond and out doors or in a garage it may be time to burn kerosen that line heater is avable for carlins and becketts for surei've heard of promblems associated with cold oil but have never seen personaly i would make sure all those things i mentioned where checked good luck

everything is fine with the mechanics of this system, I even put a new pump on it. I think the cold oil hits the nozzle and stops flowing.

is the tank outdoors? are where is filter located? is tank protected from the cold ?

by the time the oil leaves the pump and passes thru th enozzle fee line to the hot nozzle it should be warm and fine. Earlier, in the tank, the line(s), the filter(s) etc. are another story.

That you (in addition to the oil co) have treated the oil and that it is only 25°F (or is that *minus* 25°F? -- a whole differant ballgame) says it probaply isn't the oil and that you have changed the pump says it probably isn't the pump, so that leaves the firematic and any other valves, the line(s) and the filter(s), or possibly even something else unrelated such as the primary control or the CAD cell or even the nozzle itself. Will it run fine from a can of warm oil instead of the tank? Have the filters been changed and how'd they look (tough w/ Gar-bur's unless you cut them open)? How much vacuum's on the suction line? Was the old pump screen clean?

Sounds like a restricition in your supply line. Could be due to any number of reasons. At 25° above, the oil shouldn't be waxing badly enough to cause the problem, but if there's any water in the line, it will be forming a blockage. If the filter element hasn't been changed recently, that's a good place to start.

As earthfire suggested, you could switch to a single line system. If you purge the air thoroughly, you could probably get by for a while without the Tiger Loop. With a single line, you'll be pulling far less fuel through the line, so the effect of any restriction will be minimized. And the fuel will have more time to warm up prior to hitting the nozzle. I wouldn't worry about the cold fuel getting through the nozzle, 100 psi is plenty to do the job. On the suction side, however, the maximum pressure forcing the oil through the line is atmospheric - approx. 15 psi.

have them put in a gallon of MELT DOWN your oil is jelling up with the freezing temps where having. Then if your oil tank is not full get a k-1 delivery for it does not jell up.I've been outstaight for two days for this same thing.

maine rick

sorry about that put the MELT DOWN in your oil tank

Yes this is an outside tank 2 pipe system and the oil lines run through the attic. Filters nozzles screens have been replaced. It runs fine of a 5 gallon bucket in the house. I am just confused as to why if I have good oil flow, I know the line is free, why does the cold oil, run through the pump no problem with the bleed valve open, but the oil stops flowing after a couple of minutes with the unit running?

pump

You mentioned a new pump........is the by-pass plug in the proper position for your application. (installed or removed per instructions)

rerun your oil lines using flare fittings do top take offs using snorkle gauge treat tank with chemicals to prevent gelling run oil lines in living space not attic test pump psi
