radiate fire

Smokeless models use a dual‑wall design with secondary combustion. Cold air enters through bottom vents, is heated as it moves between the walls, and is released through upper vents where it helps ignite unburned gases. That secondary combustion greatly reduces visible smoke while producing near‑360° radial heat distribution.

Typical diameters are about 26–29 inches with heights around 15–19 inches; at least one model specifies it accepts logs up to 18 inches long.

Some units ship fully assembled, while others require adult assembly (tools are provided for those models). Portability features vary by model but commonly include integrated handles, foldable parts or legs, and lighter weights intended for travel.

Several outdoor fire pits include removable ash pans or slide‑out ash pans—some models even supply a scoop—to simplify emptying and cleaning after use.

The results show smokeless wood‑burning fire pits, propane gas fire tables, and electric freestanding fireplaces, using wood, propane, and electricity respectively.

Smokeless wood‑burning pits advertise heat up to about 100,000 BTU; propane fire tables list roughly 40,000–50,000 BTU; electric freestanding fireplaces are listed at about 5,100 BTU.

Outdoor units are commonly constructed from 304 stainless steel or other steel/metal frames; some propane tables use PE rattan for exterior styling.

Propane fire tables produce high heat (around 40,000–50,000 BTU), often include a removable lid or top to convert the fire area into a coffee/tabletop, and use a simple knob for ignition and flame control. They typically come with decorative media (lava rock or glass) and a protective cover for storage.

Common features include detachable stands to elevate pits above decks, non‑slip feet, optional spark‑resistant mesh lids, removable ash pans, all‑weather or rustproof finishes, and PVC protective covers for tables.
