.50 nozzles

I've yet to run into a heating or water heater that uses .50 nozzles. What units use such small nozzles????

How about

a Miller or Coleman or intertherm mobile home furnace. Or a very small unit heater. I was told there is some euro stuff fired at .40. You need real good filters for these.

lchmb

had one today

A very small thermopride...Running with a .50 with 120 on the pump..The unit is rated for 70,000 and the house is a 16x20 one room house with a loft on the back. They are out there just not alot...

Checkout Dunkirk EV

They have a 56K boiler that uses a .45

We've ,

Been installing a few Buderus units (115/21) that fire a .50 @150 psi equaling .61 gph. The CCT/Carlin EZ-1 burner specifically.

Make sure the filters you're using are the best you can get and the oil lines and tanks are new, and there should be very few problems.Like Bill Nye,NTSG, I saw a few on mobile home furnaces back in the day. When we finally see the fuel quality go to where it belongs, we will be able to fit a boiler of the PROPER size for some of the new homes being built. Even the smallest of boiler available today are too big for some of the places that they are going into.

I saw a burner last spring at Brookhaven National Labs that modulates between .35 and .5 gph. With the smallest equipment available to us in the field, we would be in the "condensing" mode way too often, and the equipment would pay the price for trying to "give us the right firing rate for the right heat load".

Wish I had the answer to the equipment equation of this puzzle. Low firing rates ARE achievable, but the equipment just isn't here yet. Chris

Tons of 'em

Mobile home units by the truck load use from .5 to .6
As others have said, you need a very good oil filter. Try a Garber spin on type with an empty General or Unifilter cup in front of it acting as a sediment trap. I have no extraordinary problems with small nozzle burners that are set up in this manner. Gotta keep 'em clean, that's all.

There are even smaller

on the way, 0.15 anyone???

ones you install a f-3 and know why and what and how

and when to do it .......i have a.60 in myF-3 on my pinner weil Mclain :)i also have a .35 80 that i have considered installing...:)) that Alan Mecurio really had my interest with his test of the herrmman modulating burner....now Fire Dragon comes along and ripps the lid off my brain cell with a .15 :)id have to do my home work dialing the weil mclain and theburner down that far...however with the stager for the riello 20 and a little bit of calculation....:) nah...i let some bolly else be the guinea pig on that one:)

Whayt's that used on?

The US Army's mobile units with the photo power generating cell?

Firedragon_4

Yup, that and oil-fired

stoves, clothes dryers and point-of-use water heaters. Some of this is already in development and the P-O-U DHW heater is in use in Japan and China.

Two-stage residential

has been in use in Europe and the Orient for over 20 years. I have a two-stage in my home and have since 1985. It is a Euro production model.

Watch for this, it's the next big thing: up to 15% savings over equivalent single-stage burner.

That means up to 18% lower NOX levels with interrupted ignition, lower fuel bills, happy customers. I bet that will save and get us some new accounts.

Oh yeah, and they run much quieter and put out virtually no CO on low fire, FACT!

All this and we're still screwing around with fanatasy concepts and visions, lets' get REAL!

Hey, you know when you've had a vision more than twice and it turns out not to be real, it's called a hallucination! But that's only according to a shrink! ;-)

Valiant boiler. European brand. Good luck.

Olsen

ECR International's forced air division Olsen has a complete line (lowboy, high boy, and counterflow/horizontal) that use a 0.50 gal @100 psi.

For more information, please visit www.ecrltd.com, selsct products then oil furnaces.

.50

Sure we install, clean and service .50 stuff all the time!!! why not?? Most houses can get by with much less btu than you guys think. My 1981sqft cape has a heat loss of 42,000 btu. what do ineed .75 for?? if Ihad Icynene insulation i could use even less. We use the Thermopride .50 furnace a fair amount. A 46 x 26 ranch is only 1126 sqft . Even if you figure 35 btu a foot that's only 42,000. I go in those houses and see guys putting in .85 furnaces, why? we don't have nozzle plug problems but we filter them right. Double or tripple with a low micron in the mix. You can fire almost any 3 section boiler at .50 if you want to. Well let me clarify that's .50 nozzle but we're running higher pump pressures so the rates higher than that. Take an old AFG put on imterupted duty 14k transformer, an oil delay valve, post/pre purge, down size the nozzle and up the pump pressure, you'd be amazed at how much cleaner your boiler is 6 months later. If your not hot rodding it your not having fun!!!!

Even better

Try a Riello in a small boiler with a .35 or .40 and spin your pump at 185psi with trippple filtration. You can pretty much throw your boiler brush and soot vac away.
