SMUDGEPOT

Smudge pot

A smudge pot is an oil-burning device used to prevent frost on fruit trees. Usually a smudge pot has a large round base with a chimney coming out of the middle of the base. The smudge pot is placed between trees in an orchard. The burning oil creates some heat, but more importantly, a large amount of smoke, particulates, carbon dioxide, and water vapor. This artificial smog forms a "blanket" that blocks infrared light, thereby preventing radiative cooling that would otherwise cause or worsen frost.
