Description

The invention relates to auxiliary burner devices designed to run long-acting autonomous burner devices, which are based on the technology of burning fuel in an atmosphere with a high content of superheated water vapor.

A burner device is known (RF Patent No. 2373458, F23C 99/00, F23L 7/00, 05/26/2008), comprising a housing, an integrated steam generator with steam nozzle and a gas generation chamber. In the housing, on the side, there is a nozzle for exiting the torch, and the steam nozzle is located in the gas generation chamber coaxially with the nozzle and is connected to the superheater. The built-in steam generator consists of three separate blocks, the superheater being made in the form of an annular chamber, and the steam separator is located inside the superheater. The evaporator tank is located on top of the steam separator and superheater. All three blocks of the steam generator and the steam nozzle are connected by pipes and do not have common walls.

The disadvantage of this device is that the resulting torch is directed horizontally. Such a direction of the flame is not acceptable for starting autonomous long-acting burner devices where a vertically located flame directed downwards is required.

The closest solution to the technical nature and combination of essential features is a burner device (RF patent No. 2523591, F23C 99/00, F23D 11/44, 04/09/2013), which contains a coaxially located housing, a steam generator installed in the housing and consisting of a vaporizer tank, a steam separator made in the form of annular chambers, a superheater made in the form of a tube with hollow walls installed inside a vaporizer tank, and a steam nozzle installed at the bottom of the superheater with the possibility of supplying steam and mix e him burning mixture through the superheater.

A disadvantage of the known device is the direction of the torch vertically upward.

The present invention is based on the task of creating a starting burner device with a torch pointing down, which will significantly reduce the startup time of a stand-alone burner device of long duration.

The problem is solved by the original location of the nodes used.

According to the invention, the starting burner device comprises a housing, a steam generator, consisting of coaxially mounted and connected tubes of the evaporator tank and the steam separator, made in the form of annular chambers, a superheater made in the form of a tube with hollow walls, and a steam nozzle, as well as a furnace made in the form of an annular chamber,

According to the invention, the superheater and the steam separator are installed inside the furnace, coaxially with it and so that the inner cylindrical wall of the steam separator is the outer cylindrical wall of the superheater.

According to the invention, the steam nozzle is mounted on top of the superheater coaxially with it in the inner cavity of the evaporator tank, with the outlet downward, and the evaporator tank mounted on top of the superheater. The steam nozzle is installed so that the steam flowing out of the steam nozzle penetrates the flame of the burning fuel, producing a torch directed downward through the superheater.

This configuration allows you to create a vertical torch pointing down.

The device itself is installed on top of a long-acting burner, the torch is sent to the inner space of the burner. Starting device with a volume of the tank-evaporator of 100 ml can work for 30 minutes. The starting device can not only boil water in the tank-evaporator of the long-acting burner device, but also bring the steam pressure to the required value, which greatly facilitates the launch of such a burner device.

Thus, the proposed technical solution due to the original location of the nodes, as well as due to the vertically directed torch, allows you to create an auxiliary starting burner device designed to run autonomous long-acting burner devices, which are based on the technology of burning fuel in an atmosphere with a high content of superheated water couple.

The essence of the technical solution is illustrated in the figure.

General view of the device - FIG. 1. The inventive device consists of a housing 1, a tank-evaporator 2 with a filler neck 3 for water, a steam separator 4, a superheater 5, connecting tubes 6 and 7, a steam nozzle 8. The housing of the device has a furnace 9 with a filler neck 10 for liquid fuel. The evaporator tank 2 and the steam separator 4 are made in the form of annular chambers. The furnace 9 is made in the form of a ring-shaped cup, inside which a superheater 5 with a steam separator 4 is placed, and the steam nozzle 8 is mounted on top of the superheater 5 coaxially with it in the inner cavity of the evaporator tank 2 and is directed downward by the outlet, and the evaporator tank 2 is mounted on top of the superheater 5.

The device operates as follows.

Distilled water is poured into the evaporator tank 2, and liquid fuel is fed into the furnace 9 through the neck 10. The fuel is ignited, the flue gases enter the gap between the inner surface of the housing 1 and the outer surface of the evaporator tank 2. The water in the evaporator tank 2 boils and the steam flows out of the steam nozzle 8, penetrates the flame of the burning fuel, thereby producing a torch directed downward.

There are experimental data.

When starting an autonomous long-acting burner device with a 1.5-liter tank capacity by starting the burner device, the start time is 5 minutes, instead of 30 minutes when starting with dry fuel in an amount of 200 g, placed in the furnace of the device.

Claims (1)

A starting burner device comprising a housing, a steam generator, consisting of coaxially mounted and connected tubes of the evaporator tank and the steam separator, made in the form of annular chambers, a superheater made in the form of a tube with hollow walls, and a steam nozzle, as well as a furnace, characterized in that the furnace is made in the form of an annular chamber, a superheater and a steam separator are placed inside the furnace and coaxially with it, and the superheater and steam separator are installed in such a way that the inner steam trap is of cylindrical wall of the outer cylindrical wall of the superheater and steam injector mounted in the internal cavity of the evaporation tank so that steam flowing from the steam nozzle, the flame of burning fuel permeated producing torch, directed down through the superheater.
