Kinda like using smudge pots to heat the local air within a grove. Florida citrus growers will do that until temps get too low or winds are too high to retain the heat and they are forced to ice everything down.
That was my chore when I was a teen :lol:. Light the smudge pots at various locations around the portable concrete plant in the mornings. Had to get the one in the operator's shack first, that's where the old man's coffee pot resided :lol:. The water pumps and critical plumbing would wait. "Coffee First!" :rofl:
