Through burning, not only the volume reduces greatly, still can utilize the heat electricity generation, the heat supply that burn the production, reaches the purpose of energy reuse. Therefore, the incineration technology has become a garbage disposal technology which is generally adopted at home and abroad at present. However, direct incineration of waste has many problems, such as: (1) secondary pollution problem; acidic gases (HCl, HF, NOx and the like) generated by burning organic matters in the garbage components, highly toxic chlorine-containing high molecular compounds (generally called dioxin-like substances) and fly ash containing Hg and Pb can cause environmental pollution. (2) The problem of damage of incineration equipment; the chlorine-containing compounds in the garbage form corrosive gases such as HCl in the furnace, and metal parts in the furnace are seriously corroded at the temperature of more than 300 ℃. In order to overcome the above-mentioned disadvantages of the waste incineration technique, a waste pyrolysis technique, which is an alternative technique to the waste incineration, has been developed and applied.
