A nonflammable burner, comprising:

• a can having an open top, sidewalls, and a bottom, said can including holes in said sidewalls and said bottom;
• a plurality of hollow legs coupled to said bottom of said can, each of said hollow legs having an open end in fluid communication with an interior of said can, each of said hollow legs including perforations for providing fluid communication with an interior of said hollow legs and adapted for providing fluid communication with an ambient environment, wherein a portion of said hollow legs have a first length and a remainder of said hollow legs have a second length wherein said first length is greater than said second length;
• a tray adapted to be positioned on a ground surface, said tray engaged with said plurality of hollow legs wherein said portion of said hollow legs pass through said tray and said remainder of said hollow legs rest on said tray wherein said bottom of said can is spaced apart from said tray by a distance equal to said second length;
• and
• a plurality of open-ended conduits extending between said sidewalls of said can and providing a fluid flow path there through, each of said conduits adapted to admit the ambient environment therein, each of said conduits having perforations for providing fluid communication between said fluid flow path and said interior of said can.

A nonflammable burner, comprising:

• a can having an open top, sidewalls, and a bottom, said can including holes in said sidewalls of a lower half of said can and said bottom;
• a plurality of hollow legs coupled to said bottom of said can, each of said hollow legs having an open end in fluid communication with an interior of said can, each of said hollow legs including perforations for providing fluid communication with an interior of said hollow legs and adapted for providing fluid communication with an ambient environment;
• a tray adapted to be positioned on a ground surface, said tray engaged with said plurality of hollow legs wherein said bottom of said can is spaced apart from said tray;
• and
• a plurality of conduits extending between a portion of said holes in said sidewalls of said can, each of said conduits including two open ends adapted to be in fluid communication with the ambient environment wherein a flow path extends through each of said conduits, each of said conduits positioned at a unique height in said can, each of said conduits including perforations for providing fluid communication between said fluid flow path and said interior of said can.
