The invention relates to the power industry, is intended for burning solid organic fuel and waste of different fractional composition and is an improvement of the known device according to the basic author. No. 985656.

The aim of the invention is to improve the economics by increasing the efficiency when incinerating different fractional wastes.

1 shows a heat generator longitudinal section; FIG. 2 is a section A-A in FIG. 1.

The heat generator includes a housing 1 with a displacement chamber 2 coaxially positioned, equipped with 15 "air nozzles 3 connected to it at the entrance through pinch 4 by a cyclone furnace 5 having tangentially mounted burners 6 and secondary blowing nozzles 7, and chamber 8 adjacent to the cyclone furnace 5 afterbirth with a fluidized bed, equipped with a rotary air distribution grille 9 and two grunts of air nozzles 1O and 11. Mixing chamber 2, furnace 5 and afterburning chamber 8 are installed with a gap relative to the walls of housing 1 and form with the latter hlazhdayuschuyu jacket 12 provided by the air from the pinch 4 and air nozzles 3, 7, 10i11. The mixing chamber 2 is provided with an outlet 13, and the afterburning chamber 8 is equipped with an outlet 14, In the furnace 5, a nozzle 15 is installed to ignite and heat, and the housing 1 is equipped with a pipe 16 for blowing air. The furnace 5 is connected to. camera 8 with tape 17. Under device 8, a device 18 is placed for slag output. Air nozzles 10 located above the grille

roar flow, organized by supplying secondary air through the nozzles 10. Slag when the grate is rotated enters device 18, Liquid slag formed not in the bottom section, the stack is down, granulated in a fluidized bed, 2 sludge.

9, set tangentially to the conditional circle with a diameter equal to the diameter of the notch 17,

The heat generator works as follows.

Through the pipe 14, air is supplied to the cooling jacket 12, which cools the furnace 5, the mixing chamber 2 and the 8-afterburning chamber, entering simultaneously the clamp 4 and the nozzles 3, 7, 10 and 11. At the same time, fuel is fed into the furnace 5 through the nozzle 15 and Ignition and heating of the firebox 5,

After the heating of the furnace 5, the multi-fractional combustible waste is supplied to the burner 6. The flow of the air mixture descends along the wall and carries away the waste, which partially burns out along the way.

When the flow is turned upwards, the unburned coarse fractions and ashes are separated and, through the tapping line 17, enter the afterburning chamber 8 into the rotary grate 9. Separation is facilitated by the suction of part of the gases from the furnace 5 and their removal through the nozzle 14. in the mixing chamber 2 (due to the addition of cold air), passes through the outlet 13 and enters the drying unit.

Unburned fractions and ash are fed to the rotary grid 9, on which due to the air supply under the grid 9, a fluidized bed is arranged from the nozzles 11. Incomplete combustion products in the layer are burned in a vortex flow, organized by means of secondary air through nozzles 10, whose axes are tangential to a circle, with a diameter equal to the diameter of the notch 17,

Shpak when turning the grate 9 enters the device 18, Liquid slag, if it is formed on the fly-wheel 17, stack down, granulated in the fluidized bed

Formula invented by the generator St. No. 985656, characterized in that, in order to increase efficiency in the incineration of multi-fractional waste, in

The body is additionally equipped with a afterburner with a fluidized bed adjacent to a cyclical furnace and equipped with a rotary air distribution grille with two groups of air jets located respectively above and below the grille, and the nozzle in the group located above the grille is tangentially to the conditional circle with diameter equal to the dia-, meter years.
