now go live somewhere where that doesn’t exist. Urbanites on their roll it to the curb and watch it go away trash disposal. Posted in Misc Hacks Tagged barrel, burn barrel, fire Post navigation We’ve seen similar designs used to supply workshop heat, too. The output of the smokeless burn barrel looks far hotter and cleaner. The design involves a lot more work than just hacking some holes in an old drum, but the results are undeniably impressive.

This extra oxygen supply helps create secondary combustion at the outlet which burns up all the matter that would normally be passed out as smoke. Secondly, the barrel-in-barrel design, paired with some smart vents, helps provide fresh air to the fire just before it leaves the barrel. First of all, plentiful air is provided to the fire thanks to the intakes at the bottom of the barrel.

Through some clever cuts and folding of steel, a single burn barrel is created from the original two that helps eliminate smoke entirely, through two clever design features. However, this design from combines two drums into one to create a barrel that burns far more efficiently with less smoke! (Video, embedded below.) Note the vent holes feeding oxygen to the fire just before the barrel outlet. Generally, they’re fit enough for purpose but can have a very smoky output, particularly when overloaded. Old 55-gallon drums are often repurposed into fire barrels with the simple addition of a few holes cut into the walls.
