The utility model relates to energy, in particular to devices for burning wood waste in the forest industry.

Known furnace for burning wood waste, which contains a hopper, a heat exchanger, a smoke exhauster, a vertical shaft with a perforated bottom, equipped with one or more perforated cups and a device to prevent arching. The glasses are arranged vertically and are supported by the open part on the grate. The afterburning chamber is made of an annular cross-section, it is bounded inside by the wall of a vertical shaft, on the outside by a secondary air heater, made in the form of two vertical collectors with horizontal pipe rings between them. One of the collectors is equipped with nozzles for supplying heated secondary air to the combustion chamber (Patent No. 2133409 IPC F 23 G 5/24).

Also known is a device for burning solid fuel, comprising a cylindrical combustion chamber equipped with a tangentially located nozzle, a gas outlet window and a grate, a fuel hopper, a fuel supply device, a blower fan, characterized in that the combustion chamber is equipped with an outer air jacket and an inner one coaxially arranged with it a cylindrical screen mounted on the gas outlet window, and the fuel supply device is made in the form of an ejector mounted between the nozzle and the fuel hopper ohm, and connected through an air jacket to the blower fan (Utility Model No. 7470 IPC F 23 V 1/38) - prototype.

Heat generator

The disadvantage of the above devices is the low efficiency and rapid burnout of the grate.

The technical task of the claimed utility model is to increase the efficiency of the heat generator.

The technical problem is achieved by the fact that in the known installation containing a cylindrical combustion chamber, a fuel supply device and a blower fan, pipes with nozzles are located in the lower part of the chamber, which are connected to the blower outlet. A heat exchanger is installed in the upper part of the combustion chamber.

Comparison of the proposed solution with the prototype shows that it differs in the following features:

in the lower part of the chamber are pipes with nozzles; the pipes are connected to the discharge opening of the fan; - a heat exchanger is installed in the upper part of the chamber.

Therefore, the claimed solution meets the criterion of "novelty.

The inventive utility model can be manufactured on standard equipment using well-known processes, therefore, it meets the criterion of "industrial applicability.

The figure schematically shows a heat unit.

The device comprises a combustion chamber 1, in the lower part of which pipes 2 with nozzles are located, which are connected to the discharge opening of the fan 3.

fuel is supplied to combustion chamber 1. The air pumped by the fan is supplied through pipes 2 and breaks out through the nozzles through the fuel layer, activating the combustion process. The flue gases from the combustion chamber are fed to a heat exchanger.

Claims (2)

1. A heat unit containing a cylindrical combustion chamber, a fuel supply device and a blower fan, characterized in that in the lower part of the chamber are pipes with nozzles that are connected to the blower outlet. 2. The heat generator according to claim 1, characterized in that a heat exchanger is installed in the upper part of the combustion chamber.
