Paraffin is the same as kerosene and this is what jet aircraft use so you may be able to persuade the refuellers at the airport to supply you, I have a 'Taylors' paraffin heater, I havent tried it yet but I'm down to my last 5 litre bottle so I thought I'd give it a try, I'll post later to let you know how I get on.
