In terms of material flow:  Through kiln body rotation, hazardous waste is evenly mixed and moved to the lower end along the inclination angle in boiling status. In order to achieve complete incineration of waste, a secondary combustion chamber is always provided. Its special structure enables several heat transfer forms to complete the process of garbage drying, volatilization analysis, garbage ignition until burning out. Complete incineration is finished in  secondary combustion chamber.

  In terms of heat conduction: most of the waste materials in Zhengzhou Taida hazardous waste rotary kiln are heated by high temperature gas generated in the fuel process and the heat transmitted by the kiln wall. Meanwhile, spontaneous combustion of  hazardous waste will also generate a certain amount of heat. After entering incinerator, solid waste materials will be heated first by auxliary burner's flame and heat radiation kiln wall to complete the process of heating, moisture evaporation, combustion and thermal desorption.
