is the paraffin pre-heater tube supposed to be used only once the meths has pre-heated ? There is no question of igniting teh paraffin pre-heater tube by itself ?
Paraffin has a reasonably high flash point, so even the preheat burner has to be hot enough to vaporize the finely atomised paraffin spray that otherwise would be at room temperature. Hence the initial preheat with methylated spirits/methylhydrate/Iso-Propanol-Alcohol. These three listed hydrocarbon liquids all have low Flashpoints, so light very readily at room temperature. Methylated spirits is methyl alcohol, with a blue colouring dye & bad smell added it, to deter individuals from trying to drink it.
@Thomas Lawry @Derry Tift. You obviously have no idea. There is no need what-so-ever to preheat the preheater. Either use spirit in the spirit cup which will take around 3 minutes OR, use the RAPID preheater which will take around 30 seconds, possibly nearer one minute if the temperature is around or below freezing. There is neither need nor point in using both. The principle of operation is quite simple, air and fuel are taken under presure from the tank, mixed together and ejected via an atomiser, the resultant very fine spray lights readily. See here for one example, there are others. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wbGQboXBXjc.html
@@yorksploughboy803 Thankyou. I was camping at -25C in alpine conditions.... at this temp, kero/parrafin doesn't atomize very well. Sorry I wasn't clearer. One doesn't always know the operating environment and or conditions, for the intended use of the lantern.
@@thomaslawry5238 -25C ? WOW, that's COLD ! Now that you've explained the circumstances, I can understand why preheating the flame tube of the rapid preheater would be necessary. I've only been at -20 (skiing in Romania) and never tried lighting a lantern at those temperatures. I apologise for jumping to conclusions and unwittingly insulting you by making a statement which questioned your knowledge about rapid preheaters when clearly you know more than me. Again, I apologise.
@@yorksploughboy803 No worries mate. It was -20C during the day, and dropped overnight. I have never been so cold. Campers who had propane lanterns were wondering why their lanterns and stoves burned with with a feeble dull yellow glow and had virtually no heat. Kero/paraffin while a little slow to start, was unaffected by those temperatures. It was this time of year too.
