Re: Diesel fuel and Heating Fuel C&E tax\'s etc.

I agree that at moment I don't think anyone would care ... but IF the Red concession is lost - then I think a different story.

Seconbd if you are a household with Heating Oil and your consumption starts to increase .... in line with Red giving out etc. - it will look rather fishy ...

I don't know how C&E / Oil Suppliers work in UK - but out here all litres supplied in tax concession uses are regultaed hard and increase of consumption would be detected quickly. In fact out here - a household has apply for a Licence for x litres and then present that to the supplier ... without it - you have no chance.

I'm sorry that I cannot answer on UK C&E .... as its not my market or field - mine is Fuel quality and quantity.

Thought .... the lack of action by C&E is probably down to the small amount of abuse ? Should it increase or they were to get to know that eg TOME was using Heating oil in his twin Turbo Sabres at xxxx gals per hour - he would be in the poo faster than a rabbit gets .......... !

Cheers ........ at least we still have Red at the moment ....
 
Re: Diesel fuel ... Duncan ... not quite true ...

Ignore the mudslingers Nigel and please keep posting....to the non technical amongst us you are always illuminating and educational!!
 
Thanks for support ... more details ...Red Diesel

OK ... because another had Burner problems with using agri-diesel - I have looked into it and try to find out why the soot problem occurred ....
I am also looking to see what changes may be happening on Red market ... so far it is still BS 2869 and the EN equivalent. This makes max sulphur still allowed at 0.2% .....

Interesting though is the change of Viscosity between Summer and winter grades and the less stringent req'ts on winterising cold properties.

For those interested Red diesel lowest spec Cetane is 45, whereas road ULSD is 49 (UK only applies - as various other areas have different climate realted specs).

Comparison of various qualities are being made to see if we can find an answer to the soot problem ... my money is on the burner tips ..... as Red has an ashing value of 0.01%wt .... which although not fantastically low is not so bad ... in fact is same as ULSD ... UK spec again.

Please tell me when I get too techy and I will try and devise easier understandable text !!!!
 
Re: Diesel fuel ... OK .... Smoke ...

That is a different matter all together and actually red should not smoke more than ULSD ... ok it's density is higher etc. but that should help with injection.

Smoke is another issue .....

White can be due to two reasons .... not enough fuel and too much air - common at low revs. Second can be steam based on either water into exhaust too close to engine or fault in engine.

Black - common at higher revs when fuel is excessive and partly unburnt .....

Blue - usually oil related.

Other ?? Dunno must be cooking oil or Chip pan !!!!
 
Re: Different types of heating oil

The burner in question was an Esse "vapourising burner" .. quite a simple metal pot with air holes where the oil vapourises and burns. No wick or pressure jet.

This was over 20 years ago, but they still seem to use the same technology.

http://www.ouzledale.co.uk/pdfs/manuals/oil-vaporising-operate.pdf

The instruction quote two possible forms of heating oil ..

"Note: FUEL - Your cooker may have been installed for use on either Commercial Kerosene, 28 sec to BS 2869: 1983 Class C2 or 35 sec ‘Heating Oil’ (Diesel). You must use the correct grade of oil. Check the data plate on the inside of the Accessory box (Fig. 2)."

Needless to say we didn't read these instructions before trying the Red in the stove.

Re: Different types of heating oil

On of the problems with all these Classifucations is the spread of products they carry ...

BS2869 actually covers near all grades of "Heating Oil" and Concessionary Diesels ... (OK - to those in the know - I have used HO and Concessionary as lay-terms so that it is easier to understand ...)
You have to start delving into the Class #'s ... such as Class 2, Class A2 etc. etc. Then you start to see the different grades - but often they will have EN or other ID's that will not mean much to man in street .....

It sounds daft - but often we as Quality guys get asked to analyse cargo's and get given a EN / BS number to work to ... but not a Product name. So if you think its bad for you guys out there - imagine what it is like for us to match not only BS / EN guides but also the additives - given often only a very short time to come up with the solutions ! Another factor that tends top throw spanners in the works .... each company will have its own name for a product .... plus data such as 28 secs, 35 secs etc. is "old-hat" - rarely used nowadays .... most labs and traders are well past that sort of terminology now..... preferring generic names until they get it into their blend / storage tanks etc.
 
Re: Different types of heating oil .... oops !!

Now that's naughty ..... Gandy Goose !!

IMHO - if you use a different spec to that which manufacturer recc'ds - then of course there is no comeback for you if engine goes a over t .... Your warranty is void.

If you use a different spec on an older engine - you just may exceed the engines capabilities ....

I would not advocate swapping fuels / sources ... often it leads onto other problems or effects .... OK - using Road diesel instead of Red is no problem legally or physically in effect. But other way round is illegal. Use of Heating oil may also be illegal as the classification on it may not allow such use.

I have to back off from this sort of discussion of alternative uses as it can bring me to dangerous ground ..... I think you can appreciate that.

All I say is that beware that there are a myriad of grades and classifications of oil out there and "biting" at one may be an error that will not bode well. Please take care ....
