It’s janky looking but it should work. In case it isn’t intuitive what this is, this is a device to evaporate liquid propane and accumulate it for burning. Sadly it isn’t going to look pretty while doing it.
The problem with prototyping is that you don’t just make mistakes you hit upon fundamental design flaws. I made a frame for this coil out of luon it is a bit flimsy but it will hold. The problem is that the coil doesn’t let the luon sit flat. I should have raised the holes slightly on each post. Now it won’t fit in the frame I cut for it. Oops.
Well it’s just a prototype anyway, it’s allowed to have duct tape. More importantly here is how it should work. A full propane tank is attached upside down. There is a 1/4 safety valve and a fine control valve on this end. You need to slowly feed the liquid propane out of the tank so that there is negative pressure, allowing it to boil and giving it time to evaporate.
On the top side, the gas accumulates in another small tank. Because there is pressure here another valve is in place for flow control. Finally a stop flow quick connect let’s you hook up the device and disconnect it without venting the whole system.
I’ll take it for a test run next week!
