PROBLEM TO BE SOLVED: To provide a natural ventilation system of incinerator made of recycled drum cans, which suppresses incomplete combustion, and allows combustible litter (mainly a variety of paper) discharged from general homes to burn well, and is excellent in durability. SOLUTION: Two pieces of recycled drum cans are made into one unit of incinerator. One piece is made into an outer drum, and the other is narrowed down to reduce the diameter into an inner incinerator, thus they are made put in double structure. Cooling air enters it from below and passes the space in the double part, thus this incinerator supplies a required quantity of air at all times to the refuse upper combustion part by natural ventilation.
