  • the waste tires are mainly composited high polymer compounds, and their caloric value is about 34 MJ/kg which is higher than 29 MJ/kg of a standard caloric value.
  • the general composition of tires is 43.5wt % of styrene-butadiene copolymer, 32.6wt % of carbon black, 21.7wt % of oil, and 2.2wt % of additives such as sulfur and zinc oxide except for iron cores and nylon.
  • the Ministry of Environment prohibits the usage of the waste tires as fuel since they produce various environment pollutions such as sulfur oxides, non-burned hydrocarbon, and sooty smoke when burned.
  • waste tires are recycled as footpath blocks, recycled tires, recycled rubber, art fishing banks, and buffers of any structure, but their appliance is limited. Also, scrapped materials and pollutions are produced when the recycled products are manufactured, and environmental pollution will be caused when they are scrapped.
  • a method to produce fuel without recycling the waste tires is tried.
  • a pyrolyzing furnace is used to pyrolyze the waste tires, and the method is divided a direct heating method and an indirect heating method according to the heating method of the pyrolyzing furnace.
  • the direct heating method has a risk for explosion since a flame produced when the waste tires are heated is chemically reacted with the oxygen contained in air in the furnace. Also, the oil produced by the direct heating method contains moist and glass carbon, which causes the quality of the oil to be worse.
  • the indirect heating method has no risk for explosion different from the above the direct heating method, but it has lower thermal efficiency and uses most of the oil obtained as a by-product as fuel, which causes the recycling system of the waste tires to be lowered in economy aspect and causes difficulty to treat carbon obtained as a by-product.
