1. Direct combustion furnace: one of the most common garbage incinerators. The direct combustion of garbage produces high temperature flue gas, and the pyrolysis of garbage can achieve the effect of harmless treatment and resource utilization.

2. Fixed-bed incinerator: it is a kind of garbage treatment equipment with a fixed chemical reaction bed in the device, which makes the garbage react physically and chemically on the reaction bed. The pretreated solid waste is put into a fixed bed furnace, heated to a high temperature outside the furnace, decomposed by combustion, discharged after treatment, and the solid residue is extinguished to produce harmless substances.

3. Fluidized bed incinerator: It is a kind of waste treatment equipment that suspends and burns waste in the bed under the action of high-speed airflow and through constant eddy friction in the bed.

4. Rotary kiln incinerator: it is a kind of waste treatment equipment that puts waste into rotary kiln for pyrolysis and combustion. Through the inclination and rotation of the furnace body, the garbage is heated continuously, and the efficiency of garbage combustion and the effect of waste gas treatment are improved.

5. Microwave radiation furnace: it is a waste treatment equipment that makes waste produce heating, pyrolysis, combustion and other reactions through microwave radiation, so as to achieve the purpose of harmless treatment and resource utilization of waste.

The above-mentioned garbage incinerators have their own characteristics and limitations in application, so it is necessary to choose the corresponding models according to the types of garbage and the treatment scale. At the same time, it should be noted that the waste incinerator will also produce a certain amount and kind of waste gas and waste residue, which needs to be treated later to reduce the environmental pollution.
