WASTE DISPOSAL METHOD Russian patent published in 2023 - IPC F23G5/02 

FIELD: waste disposal.

SUBSTANCE: invention is related to a method for waste disposal and can be used for the disposal of household, agricultural and industrial waste. The method is carried out in a thermoreactor containing three functional zones. The first functional zone is a zone of pyrolysis gases located above the grate. The second functional zone is a fluidized bed zone located near the grate. The third functional zone is a combustion chamber located under the grate. The amount of heat generated by the reactor is determined in advance, and the waste pyrolysis gases are supplied to the zone with a flow rate of up to 12 kg/sec, ensuring combustion of the waste with the heat generated by the reactor. At the same time, a tangential supply of steam with a temperature of not lower than 400°C is provided in the fluidized bed zone and tangential supply of oxidizer to the fluidized bed zone and/or to the combustion chamber. In the fluidized bed zone between the inner surface of the thermoreactor and the grate, an electric field with a voltage of 1 kV to 10 kV is created. Moreover, the electric field is organized with varying intensity in the range (1.0÷2.0)×10⁴ V/cm.

EFFECT: increase of completeness of waste disposal, including wet waste, and increase of efficiency of the method.
