Looks like a clone of a Trangia burner, without the simmer ring (as such, it'll be more suited to boiling water than controlled cooking).
Normally, that would fit into the Trangia windshield/pot stand arrangement, to position it in the optimum place under your pot. In the absence of that, I'd suggest obtaining or molishing something like the Trangia Triangle to serve as a stand. Either way, you want to shield it from the wind as much as possible. These burners are very efficient, but don't burn anywhere near as hot as gas.
A fire steel is a surprisingly effective way of lighting these burners. Cigarette lighters work well, too, of course, but you need a bit of a knack when using matches. To extinguish, you simply drop the lid into place (though allow it to cool properly before screwing it on tight, otherwise you'll have a vacuum to fight when you next come to use it).
I recommend the Trangia fuel bottle, with its special push-button dispensing lid - makes it really easy to avoid spillages. But practically, there's no reason you can't use the bottle meths is supplied in (or smaller nail varnish remover bottles are good for small quantities). You should also be able to store a good ~20 mins worth of fuel in the burner. Avoid Sigg-style aluminium bottles designed for water rather than fuel - alcohols can strip the oxide layer from the inside.
