Oil burners need standard tank AND micron oil filters?

D107

from a pro:

"JMO, but you can't have enough filters if you don't have at least three. (LOL) Common sense says the more you change them the cleaner the oil, FACT!

A piece of steel will harbor bacteria and always has. Bob Tatnall did a presentation on this years ago at Brookhaven and it was startling. The only way not to create bacteria and algae is inert tanks (Roth, Dehoust), fiberglass tanks and aluminum tanks."

On another thread on this site, a wallie says: "...The quality of oil is basically out of our control, and is now the weak link in the chain. In 1986, 85% of no heat calls were electrical component related. In 2003, 75% of no heat calls were oil related."

So is it the quality of the incoming oil, the refining, the conditions in the HO's tanks, or poor maintenance/filtering? Or all the above?

Thanks,

Been reliably told that with today's dirtier oil and

narrow nozzles and high pump pressures, both standard and fine micron filters are recommended. From a maintenance standpoint, many companies don't like to deal with two filters. A very good installer has said that if the micron filter is NOT maintained properly the burner can be stressed. I would think that the burner might be stressed anyway if only the standard tank filter is used due to particles getting through.

I had thought that maybe a garber spin might be a compromise. But would it be advisable for a homeowner to stock some of the micron filters in case the servicing company finds them difficult to stock?

Seems like for optimum combustion good to replace filters twice, maybe October and Feb?

Thanks,

Filter

If the oil tank is properly installed .it would not "breed" sludge.

Filter changes..... A better method is installing vacuum gauges before and after the near burner spin on filter and only change if there is a difference in vacuums. Change the utility filter at the tank yearly and change
if both gauge are running high.

Sludge

Our biggest proplem is sludge which is produced when water is present.Through bad tank pitch or top feed tanks. A bug will live between the layer of water and oil, eat the oil and sh!t sludge which is also sulphuric(excuse spelling )acid ....


Dual filtration in "series"......the second filter should be of lower microns...The same is useless..If it passes the first it would pass the second..

I understand some of the spin on types are not all lower...

for burner mpo84 or Buderus G115 84K both firing rate 64 net

home is 47Kloss/100K gain.

filters: General 2A-17A filter at tank (variable mesh sizes available but comes with 60 micron. options for type of bowl gasket and epoxy lined or uncoated) and a Garber 10 micron with disposable spin-on filter and filter restriction indicator at burner. I think pipeline to burner is 3/8"; not sure.

I agree with Dave

note that unless you're on kero or burn 250gal yr an A25 is too small.

I put 2A-700 at the tank and a micron at the unit and have had no problems.

The large general gives you a coarse pre filter and good flow and then the micronic takes it from there and with vac gages or gae you can tell when to change, I can go 2 years.

Oil is now re cracked at the refinery and they are cracking asphalt and tar and coal to get more product and that is plugging your filters.

Good Set up

Sounds good......With running low input fires... If I remember the G115/21 uses a .60 gph nozzle...Would be my filter set up along with the braded flex oil line for swing out door..

D107

did you mean 2A-17A at the tank, since the 2A-700 is a 10 micron

which you'd put at burner, going from gross to fine. Oil usage at this house is over 1000 gallons annually.

mpo 84 nozzle is said to be .50

I guess nozzle size doesn't always correspond to firing rate gph. I guess the buderus nozzle being slightly larger is better? Less likely to clog?

nope

General 2A-700/A 25gph felt filter with screen core, then a 1A-25A micronic at the pump, Sid Harvery's # 265 & 264 respectively.

I have a spin on for the burner but I have a box of A25 micronic filters so I use those till they're gone.

I have a Beckett F-6 1.00 80* ES noz, 175 psi pump {clean-cut}. The 175 psi really cleans the fire up {suckin soot sucks}

how small is small

is filtering down to 10 micron small
that is the size on a plan 1A-25A

Pump Pressure

The nozzles stamped firing rate is measured with 100# behind it.Todays burners are running around 150#. which increases firing rate and thus BTU input...

Smaller nozzles (.50-.65)gph have a higher percentage of failing.... yes..
