SHALOM!Given that most Turk Burners I see sorely lack explanation, there are a couple bits here with which I can help.
Inside the outer shell is a bucket shape layer of refractory cement, much like the "works" in a small foundry. Refractory cement is used because of the intense heat some of these things generate.
The blower pushes combustion air into the burn pot (like a turbo on an engine). Fan positioning forces a swirl around the inside of the refractory lining, which results in more complete combustion, typically well over 1,000 F.
Some Turks and foundries feed the fuel into the air inlet so they mix better enroute to the flame.
With a very small fan, they easily melt aluminum. With a bit more fan, steel melts. Unless photo perspective is off, or cfm output is lower than it appears, that fan is comparatively huge, more like a foundry I glimpsed that melts cast iron.
While exploring this stuff in search of a waste oil dripper that would output 30- to 50,000 BTU, I toyed with the idea of using one of these things with a tiny computer muffin fan to limit the heat to what I considered safe to use in my house.
That's about it, guys. I hope it helps.
