It is increasingly used due to its compact structure, low operating cost, and good exhaust emission effect. The main body of the vertical rotary pyrolysis gasification incinerator in the prior art is divided into two combustion chambers. The garbage enters the first combustion chamber in a continuous and quantitative manner, and undergoes a process of heating - drying - pyrolysis - gasification - solid combustible combustion. The flue gas generated in the first combustion chamber contains a large amount of combustible gas, which then enters the second combustion chamber and is fully mixed with the added excess air to implement oxygen combustion, so that the harmful gases generated by the garbage are completely decomposed.
