Description

The invention relates to heating devices, is used to heat garages, service stations and other technical premises. The fuel can be used oils of internal combustion engines and other types of petroleum products having fluidity.

Famous stoves operating on liquid fuel, described in the book Sosnina Yu.P. etc. “Household stoves, fireplaces and water heaters”, M .: Stroyizdat, 1984, consist of a fuel tank, a discharge pump, an ignition tray, a fuel line and two types of burners: open and closed type evaporative burners. There are furnaces of a more complex device, with automatic control units, electric-powered fans, float devices to maintain the fuel level in the burner, or dispensers that are not applicable for a viscous medium. The fuel in these furnaces is preheated in electric evaporators. The fuel used is light oil products: kerosene, winter-grade diesel fuel. There are liquid fuel furnaces in which fuel is atomized using compressed air, steam and nozzles. All of these devices are complex both in operation and in production. The use of nozzles involves additional fuel filtration.

The open type evaporative burners proposed for consideration have a number of significant drawbacks: dependence on the fuel level in them, a lot of narrow sinuses difficult to access; the use of straight and U-shaped steam pipes, in which during the combustion process a plaque from resinous deposits and soot carbon is formed. They need frequent cleaning or replacement.

Modern car oils are a mixture of mineral oils and synthetic additives, additives and components and have a high viscosity. When mixing different types of oils in the tank, clots often form, a precipitate mixed with antifreeze and antifreeze. Previously developed burner devices are not capable of burning such fuel. Due to the high cost of kerosene and diesel fuel, the use of such furnaces is economically disadvantageous.

The purpose of the invention is the creation of a continuous furnace for the disposal of waste oils of internal combustion engines. Spent motor oils are a source of environmental pollution and, at the same time, high-calorie fuel.

Achievable technical results - the creation of a heating device, convenient in operation and necessary for the disposal of used motor oils.

The objective of the invention is solved due to the fact that the continuous furnace for the disposal of waste oils of internal combustion engines includes a housing, in the lower part of which there is a fuel storage unit with a fuel supply fitting and a metering flap, and a chimney in the upper part of the housing, characterized in that it is made inside the housing the partition forming the furnace, the afterburner, the draft stabilization chamber, and the gas passage between the partition and the fuel storage device, the furnace being equipped with a door, the metering valve It has a blade made with the possibility of swirling the flow of air and flame during combustion and with the possibility of pressing it against the partition to stop the combustion process, a nozzle-hole located under the chimney, creating traction, and two rows of secondary air supply holes in the afterburner are made in the partition .

In addition, the furnace door is made with a petal dispenser. In addition, the metering valve has a control means - traction.

The recovery furnace is made of heat-resistant steel. Parts are connected by electric arc welding.

The invention is shown in the drawings, in Fig.1 is a General view of the waste heat recovery furnace, Fig.2 is a side section of the waste heat recovery furnace.

The recovery furnace consists of a chimney (1), a housing (2), a furnace (19), a nozzle hole (13), two rows of holes (14) on a partition (12) that deliver secondary air to the afterburner (15), traction stabilization chambers (11), firebox doors (4) with a handle (10) having a flap air meter (6) with a handle (3), turning which changes the cross section between the fire chamber door (4) and the flap air meter (6). The rivet (5) is the axis of rotation of the flap air meter (6). In the furnace (19), in the lower part, there is a fuel accumulator (8), which receives fuel through the nozzle (9) from the tank. The handle of the fuel metering flap (7) is attached to the rod (16). The rod is pivotally mounted on the dispenser flap (17). The metering flap has a blade (18).

When burning, the blade (18) creates turbulence of the air flow and does not allow the flame to break away from the fuel storage (8), creates turbulence of the flame to warm the walls of the fuel storage, in which oil boils.

To start the waste heat recovery furnace into operation, heating is required. They put fuel in the firebox (19): oiled rags, firewood, paper, etc. During kindling, the flow of hot gases passes through the nozzle-hole (13) and creates a thrust in the passage (1). Opening the shutter of the fuel metering unit, we allow the passage of flame between the partition (12) and the fuel storage (8). From fuel heating, the cracking process begins with the release of combustible vapors, during combustion of which the fuel storage device self-heats up (8). Moving the handle (7) forward, we increase the amount of fuel and air vapor in the channel between the fuel storage device (8) and the partition (12).

The fuel accumulator (8) is an open-type burner, by opening the metering valve (17) as much as possible, surface combustion of the fuel can be achieved.

The blade (18), located on the shutter of the dispenser (17), creates turbulence, promotes mixing of fuel vapor and air. Burning gases pass down the channel between the fuel accumulator (8) and the partition (12), then change direction and follow the channel between the partition and the furnace body.

The partition (12) of the complex profile has bending lines that distribute the gases in a flat stream. Gases, entering the afterburner, are enriched with secondary air through openings (14), form vortex flows, reducing the gas flow rate, and create the condition for maximum burning of carbon particles. The partition (12) is heated to critical temperatures and does not contribute to the formation of heavy hydrocarbons, since it does not participate in external heat transfer, all thermal energy is spent on heating the internal volume of the furnace (19) and the air involved in the combustion process. In normal operation, the nozzle (13) is another secondary air inlet.

For the correct ratio of fuel and air on the firebox door (4) there is a petal air dispenser (6), by turning the knob (3) which changes the cross-section of the air passing into the combustion chamber cavity (19). By the shutter of the dispenser (17), driven by a thrust (16), we adjust the clearance of the passage of fuel vapor from the fuel storage (8). The blade (18) simultaneously opens a gap for the passage of air. The formation of heavy hydrocarbons and carbon blacks in the housing (2) of the recovery furnace does not affect the combustion process and they do not enter the atmosphere, but exfoliate and fall off into the lower part of the housing without harming the environment. Wide ducts do not require frequent cleaning.

A continuous heat recovery furnace is called so because it does not require a stop of the combustion process for refueling. The fuel storage device (8) is connected to the fuel tank by means of a fitting (9) and a fuel line without level control means. The top edge of the fuel tank should be at the level of maximum filling of the fuel storage (8).

To stop the burning of the recovery furnace, push the handle (7) forward and open the lobe air meter as far as possible.

A purge during which the furnace body cools down and fuel vapor is removed takes place in 15 minutes.
