High Efficiency Rotary Incineration System A combination of a rotary kiln incinerator and subsequent stationary bed incinerator provides optimum energy efficiency for traditional rotary kiln incinerators. The moving paths of both gaseous and solid wastes change when directed at the end of the rotary kiln and into the stationary bed. Higher temperature gas is mixed with lower temperature solids traveling from the first incinerator to the second. Loose solid wastes then are piled up on the stationary bed incinerator for further combustion while gas with vapor enters the second combustion chamber. The rotary kiln loosens the waste packets, then preheats them, vaporize them, and partially burns them out, but, does not aim to achieve complete combustion of the solids. However, a stationary bed incinerator will burn through the waste packets very quickly owing to their being preheated and well mixed. Key disadvantages of rotary kiln incinerators are their inherently high initial investment and high operating costs, HERIS reduces both of these problems.
