Stove

Abstract

A low cost stove which is conformed essentially by three metallic cans, wherein the first can which has the function of serving as support structure, comprises a first plurality of holes along its entire periphery which serve as inlet ports of air and oxygen therein. The second can, which is integrally attached to the interior of the first can, has the function of serving as a container and alcohol burner. Said second can or burner comprises a second plurality of holes on its lateral wall extending along its entire periphery and which are spaced equidistantly from each other, wherein said second plurality of holes in the second can or burner, are in fluid communication with the first plurality of holes of the first can. The burner further comprises on its upper wall a central hole, which has the function of serving as inlet means for the alcohol to the interior thereof. Likewise, said central hole, in use, is covered by a coin to cause that the combustion gases and flame are deviated towards the second plurality of holes for carrying out the heating of the vessel containing food or water, which is disposed on the upper edges of the first and second cans. The third can is simple and without holes and has the function of extinguishing the fire and serving as an advertising space.
