Cover 12 is fixed to container 2 with three locks. Then, one of the buttons of the control unit 11 (FIG. 2) is turned on - the “Start” button located at the top of the supply chamber 3. Through the inspection window 18 on the cover 12, it is necessary to make sure that the waste laid in the container 2 (FIG. L) has started to burn. Then you need to close the viewing window 18 (figure 2) and turn on another button of the control unit 11 - the button "Fast and the Furious. The design of the cover 12 allows you to create in the upper part of the device a centrifugal funnel-shaped flow of combustible gases that burn the waste placed in the container 2 - the primary combustion chamber, from top to bottom. Thus, the combusted waste remains in the device for a long time, while the combustion temperature reaches 1100 ° C, which ensures their almost complete combustion. The secondary combustion chamber 13 is intended for afterburning waste particles not burnt in the primary combustion chamber. At the entrance to the secondary combustion chamber 13, an air deflector 21 is installed (FIG. 3Z). The deflector 21 deflects the flow of unburned particles rising through the center of the gas funnel to the perimeter of the secondary combustion chamber 13, where they are captured by the incoming air having a high speed of movement, thereby achieving more complete combustion. Gaseous products of combustion exit through an opening 23 in the plate 22, above which a spark-extinguishing grid 20 is installed. The spark-extinguishing grid 20 prevents small unburned particles from escaping from the device. In the combustion process, it is necessary to periodically mix the burning waste through the inspection window 18 with metal

rod for stirring. The installation should be operated no closer than fifteen meters from various buildings. The operator servicing the installation must be equipped with goggles and canvas gloves.
