In my experience pressurized kero is not as dangerous as pressurized alcohol. A leaking system with alcohol could lead to real trouble but kero not so much so as it is not quite as volatile. Rather deal with kero flare-ups due to leaks
than alcohol ones.
Had an ancient kero for a long time that was perfectly fine but was also well maintained over it's life but they can develop leaks at the connections in the piping , the burners can sometimes need replacement (new ones go for about 75 usd each) and if burners are not self-cleaning can be a real pita.
Yes, you can get a burner warming pad made of fiberglass
that you soak with alcohol from a little squeeze bottle for burner priming. Works fine this way and you are not getting the alcohol all over the place.
Getting clean kerosene seems to be difficult but is kind of important. Kero and Alcohol are good cleaning
angents and kero is good for freeing seized turnbuckles etc. and can also be used to cut and extend good paraffin for lamps. Good stuff to have around anyway. Nigel Calders book on boat mechanical stuff has pretty thorough info on stove burner maintenance
Lacking a good safe propane
system I like them; reliable and reasonably safe.
pls excuse the sloppy grammer etc... quite lazy today
