re: Natural Gas Crawfish Burner - Info and Build

Yes. You would want to cut a hole in the pot and weld the heat sink into the hole so that you don't have a gab between the flat surface of the heat sink and the pot. I bought a heat sink for this but never tried it out. My thought was that I would probably melt the fins off the heat sink if it didn't cunduct the heat quickly enough into the water. Heat sinks are usually made to be pretty thick. They might work really well though, especially for lower btu burners that won't melt the long fins.

Another concept is the rocket pot that puts nubs on the bottom of the pot to increase the surface area. What I've seen stated about them leads me to believe that the increase in efficiency range only gets the pot into the low 20% efficiency range.

The following is a pot on the market that claims to boil 15 gallons of water in 7 minutes using 375,000 BTU/hr's worth of jet burners. I'm doubtful that they get the efficiency that they imply but they don't really post enough information to know what their efficiency is.

I make crawfish boilers as a hobby. I'll try that heat sink out one of these days.
