Combustion characteristics of the balsa chips were experimentally studied as the fundamental investigation of the thermal recycle system of the urban dust. The urban dust contains plastics, vegetables and lot of wood materials. Then, a balsa wood was chosen as an example of the one of the components of urban dust. A small balsa chip was burned in an electric furnace and mass reduction rate during volatile and char combustion states were recorded by the micro-electric balance. Ignition delay and the period of volatile combustion was greatly affected by the mass of the balsa chips and ambient temperature in the furnace. When the mass of the balsa chips was larger than 0.5 g, the combustion similarity was found on the normalized mass reduction rate.
