I am working on a personal project that involves a balloon filled with liquefied petroleum gas (LPG) at a pressure of $\pu{4 - 5 bar}$, and I need some kind of a device/filter that would convert it to gas (instead of liquid) at a low pressure. I used an industrial vaporizer, but it gave me something stronger than I need, and "not clean."
Basically, what i need is to build a very big lighter, like this:
As you can see, just gas, and wick that turns to a "clean" fire, without all the side effects that the vaporizer creates.
Now, as I am missing a lot of knowledge here, I would like to know if someone could guide me through how I should do this, where I can find the things I will need, what the names and definitions for the stuff needed, etc.
EDIT:
When I used the phrase "home gas," which is common in my state, I meant liquefied petroleum gas (LPG).
Here is the vaporizer I use now (it belongs to someone who knows what he is doing, I do not plan on killing myself :) )
So, I will try to re-describe my problem:
I want to get a "clean, slow flame" such as a lighter has. What I am getting, regardless of the vaporizer pressure, is an unclean flame, as though some gas is not really burning and just comes out as well, or as if something in the process makes the flame burn dirtier.
