I read recently of someone having problems melting iron, and they describe their oil burner as the type that impinges flame on the burner tube and/or the fuel tube, to preheat the fuel.
There is sort of a cult following for this burner style, but the reality is that it is one of the worst designs you can build.
People try to build better mouse traps, but end up with designs that don't work well at all.
This is a really bad way to make an iron-melting burner, is totally unnecessary, and causes all sorts of burner tube degredation.
The best way to melt gray iron is to use a siphon or pressure nozzle style burner, or a correctly designed drip-style burner.
No flame impingement is required for either of these burners.
The siphon nozzle burner is the burner of choice for me, and performs very consistently.
