Abstract

The invention relates to designs of furnaces, and in particular to the furnaces of furnaces for burning waste. The purpose of the development is the expansion of functional properties. The furnace device contains a vertical firebox, a loading hopper, grate, a burner for burning waste in the form of a liquid, located under the grate and made in the form of a box, the upper side of which has perforations for air supply, through a pipe connected to the heat exchanger located in the upper part vertical firebox; nozzles for supplying primary and secondary air to a vertical firebox are also connected to the nozzle. The burner is connected to a tank having double walls between which there is a molten salt.

Description

The invention relates to furnace devices for burning waste: oily rags, used oil filters, liquid oil-containing effluents in an environmentally flexible way.

Known furnace device containing a vertical firebox, hopper, fuel supply, grate vibrating gratings placed in a checkerboard pattern with the formation of gaps relative to one of the walls of the furnace, heat exchangers located between grate grates.

The disadvantages of the known furnace device are narrow functional properties.

The tasks to be solved by which the proposed solution is aimed are the expansion of functional properties, the possibility of burning liquid and solid wastes.

The aforementioned disadvantage is eliminated by the fact that a furnace device containing a vertical furnace, a fuel supply hopper, grate, a heat exchanger, while under the grate there is a burner for burning combustible waste in the form of a liquid, and above the grate and under the grate there are nozzles for supplying a secondary and primary air, respectively, by means of a pipe connected to a heat exchanger located in the upper part of the vertical furnace, and the burner for combustion is made in the form of an upper box whose side has perforations for supplying air to liquid fuel preheated in a heat exchanger, and the burner is also connected through a pipeline to a tank with double walls, between which there is a certain salt melt and in contact with the upper part of the heat exchanger, which is connected through

air duct with a blower fan, and in the exhaust system of the burner there is a device for cleaning combustion products.

The drawing shows a furnace device:

figure 1 - General view;

figure 2 - capacity with double walls.

The furnace device contains a vertical firebox 1, in the lower part of which there is a burner 2, for burning liquid waste, made in the form of a flat box, the upper side 3 of which has perforations 4 for supplying air from a pipe 5 connected to a heat exchanger 6 located in the upper part of the vertical furnace 1, which is also connected to the blower fan 7, the nozzle 5 is also connected to nozzles 8 for supplying primary air and to nozzles 9 for supplying secondary air located under and above the grate 10, respectively about, the burner 2 through a pipe 11 is connected to a tank 12 with double walls between which there is a molten salt 13, and in contact with the system of removal of combustion products 14 in which there is a device for cleaning combustion products 15.

In the side of the vertical firebox 1 above the grate 10 there is a hopper 16 for supplying solid fuel.

The principle of operation of the combustion device is as follows:

Through the hopper 16, the fuel, in the form of solid waste, is fed to the grate 10, and the liquid fuel (oily dirty drains) passing through the tank 12 and heated to a strictly defined temperature: (molten salt 13 provides a constant temperature for heating the liquid fuel at a certain flow rate) and through the pipe 11 it enters the burner 2, spreading over the surface of the duct with perforations 4, through which air heated in the heat exchanger 6 is supplied through the liquid fuel layer, the combustion products from the burner 2 come through grate 10 into the solid fuel layer, heat it and, together with the primary air coming from the nozzles 8, burn it.

The design of the fuel device allows heating liquid fuel to be burned to the optimum temperature with a strictly specified temperature of salt melt 13, excluding cases of overheating and self-ignition, as well as heating the air from the blower fan 7 for feeding into the burner through perforations 4 and nozzles 8 and 9, thereby providing high temperatures for burning liquid and solid wastes and decomposition of combustion products into environmentally friendly components that are further cleaned by a product cleaning device in burning 15.
