its a Wallas 85 DP - edit !

the suppliers told me it uses parafin by mistake, they have just confirmed diesel.
a web search clearly says 'diesel'

has a wound element that heats up, sits around a wick for the fuel.
and has a clicking pump.
i have had to replace to wick, was probably 20 yrs old full of wax, works ok on paraffin.
on a separate tank, would just be easier of it took the same as the engine and eber.

so how does the 35 second fuel differ from 28, hotter / easier to light ?


this came up in another thread just now:
'35 second heating oil is also known (quite well by most of us I assume) as red diesel
28 second heating oil is kerosene, and was formerly referred to as paraffin'

Paraffin has a lower flash point than diesel It will therefore be easier to ignite and probably cleaner burning.

Are you sure you have the model number right? I used to have a Wallas 90 something combined Hob and Cooker, and they were available to run on both fuels, but they were different model numbers.

Speak to Kuranda UK who are the UK importers, extremely helpful and VERY knowledgeable

The Wallis website has it as diesel. There is a manual on the website for the 85 DP, assuming you've got the right model. Or even call the Finns. English was widely spoken whereever I went over there.
 
Tnx Guys,
Yes there has been some confusion on the model number, but i have sent Kuranda a mail, see below
And here is a link to the old hob without a mask, showing the poor install

According to the internet flashpoint of paraffin is around 200C and diesel much lower 90C
So it’d be easier to light using diesel ??




Hi Simon,

You can plumb the hob to your diesel tank. You would need a dip pipe to do this.

Darren will be able to give you more information but he is on holiday today and back in the office on Monday February 12th.

Kind regards
Sarah

Doesn't seem right. I've just looked up Cetane (135 deg C) and Tridecane (94 deg C). Are you sure you haven't mixed up Centigrade and Farenheit. Anyway VicS is the man to ask and curiously enough he answered several hours ago.

Ok, so whas looking at the flash point rather than the auto ignition temperature.
Tnx, understood.
Guess auto ignition temperature is at sea level ? Not inside a combustion chamber ?

The document you are quoting for paraffin is not about the fuel we know as paraffin or kerosene.

The flash point of kerosene is between 37 and 65 °C .

Diesel fuel flash points vary between 52 and 96 °C

The flashpoint is the temperature above which the liquid must be heated, in standard test conditions, in order to ignite the vapour.
