PD-3 Fuel conditioner

Notice that Boiler Juice are selling this on the basis that it seriously cuts oil use

I am always cynical about such additives and at £18 for 250ml
:eek:

I can find nothing on google at all

So anyone used it, recommend it, think it a waste of time and money?

I've just had the same email from Boilerjuice.

Doing a quick sum, with oil now a 34p at 10% reduction it would save £34 with one bottle at a cost of £18.............£16 saved.

I too am sceptical. It would be nice if Boilerjuice could publish here their independent testing.

Still no luck with google so I am going to pass

I've seen these additives, but never any convincing evidence that they work.

As most oil boilers are pressure jet, the oil will be fed in at a constant pressure, and rate, by the pump. I would imagine that the only improvement that could be made would be more complete combustion - with a hotter flame. If that was the case, i would worry about the long term effects on the soot box and blast tube...

Boiler Juice is a domestic oil supplier who supplies a product called GFC which facilitates a faster rise to operational temperature, increases heat exchange performances, prolongs cool down time, extends the service interval times and greatly reduces emissions and as a result saves a lot of oil as well. We know all this because we just tested the GFC products in the lab in a very controlled environment. 250ml treats 1000 litres of fuel

Just as an aside they have a fuel additive for petrol and diesel that does the same job for all vehicles. Our own tests conducted on older cars showed a fuel savings of between 12% and 18%!:j

M_test, I presume you have a commercial interest in the product then? You should have permission to post in that case.

But nonetheless, can you show the results of these tests? I've worked with oil fired boilers small (household) and large (tens of megawatts), and I've yet to see a product such as this work. How does it work? Faster rise to operational temperature means it must either burn hotter (which could damage the boiler) or quicker (which is generally limited by the pump which will be fixed displacement, so you can't pump any faster). Or is it supposed to precipitate impurities out of the oil, keeping the heat exchange surfaces cleaner? If so, where do the impurities end up?

Hi this might sound a bit tekky but stay with us as this stuff is awesome!
The fuel conditioner forms a colloidal sol within the fuel. It physically combines with the fuel to create miniscule droplets less than 1 micron that forms a very stable and homogenous mix. This microscopic sized mix is small enough and stable enough to pass through any fuel filter or other purification device. During combustion a fuel droplet burns from the outside to its nucleus. The GfC process accelerates combustion because the modified fuel droplet burns from its nucleus turning it to gas which, as the temperature gets greater the pressure caused by the modified vapour is greater than the surface tension of the fuel around it and causes a micro explosion that fragments the fuel droplet. This fragmentation of the fuel droplet leads to a greater surface area for the fuel to burn and hence the fuel burns more quickley. This accelerated combustion leads to more energy from the combustion being available. No higher burn is experienced, but a far more effient combustion gives massive savings on fuel, a cleaner boiler and almost zero emissions. This research is from Cranford University and with some luck will soon be available in a reader offer in the NOTW through Martins page. It works on all fuels and is currently being used in tankers, buses and logistics companies. Anybody who uses fuel is going to love this stuff........ no company details supplied as per T's & C's:j

Why not just make the report widely available on the internet though?

The only positive reports I can find are P&O tugs seeing a reduction in smoke with conjecture that there will be an increase in fuel efficiency, and a letter from someone who works at Cranfield Uni about another totally unscientific test. The other report says they saw no advantage at all.

It doesn't sound the slightest bit 'tekky' it is the biggest load of pseudo-scientific codswallop since snake oil was invented.

Anyway you are behind the times as a simple magnet strapped to the fuel lines of cars, CH boilers cause the molecules to line up and is shown(in authentic scientific tests) to improve consumption by - let me think of a figure - how does 42.77% sound?

Complete and utter rubbish! I wonder what Martin will think about his name being used as an endorsement!!!!!

m_test - go on, post a link to the report here so that people can read it and make up their own minds.

The Queens University Belfast report doesn't seem to have a name or department on the report they have produced... who was it that did the study?
