Briefly, the invention provides an incinerator comprising a housing suspended above the ground. The housing is without a top or bottom, but includes an elongated member supporting the housing and a grate intermediate of the housing and the elongated member. Also provided is a device for aiding combustion reactions. The device includes a vertically disposed stanchion, a housing, a first open end and a second open end. The housing is supported at the second open end by the stanchion. The device also include a grid with a cross section identical to the cross section of the housing. The diameter of the cross section of the grid is less than the diameter of the cross section of the housing and the grid in rotates around the stanchion.

Disclosed is a fire pit including a fire grate formed of sheet metal and disposed in a fire pit cavity and configured to support a combustible fuel thereon. The fire grate may include a perimeter edge, a center portion disposed substantially at the central axis, an array of grate ventilation holes through the sheet metal between the perimeter edge and the center portion. The grate ventilation holes may be configured to permit airflow into the cavity and to permit ash from burned fuel to pass from the cavity to a space below the fire grate. The grate may include a plurality of stiffening portions of the sheet metal, each stiffening portion being a portion of the sheet metal devoid of grate ventilation holes. The plurality of stiffening portions may extend in a direction between the center portion and the perimeter edge and may separate the array of grate ventilation holes into distinct segments.
