The design relates to tettoenergy and can be used in devices with direct action of combustion products on heated water.5

Izvebten steam generator, containing a combustion chamber, in which are located. water nozzles and burner 1,

The disadvantage of a steam generator is a lump of reliability due to the lack of external combustion chamber devices.

The closest to the proposed entity is a steam generator comprising a housing with feedwater supply and steam exhaust connections, installed in the housing housing forming an annular channel 20 for feeding water supply fitted with SCREW fins to the housing wall and mounted in the casing supply pipe and an oxidizer, with an annular channel 25 for feedwater injection 2}

The lack of a steam generator is the B low reliability due to non-intensive cooling of the hull in the area of the steam outlet pipe.30

The purpose of the invention is to increase reliability.

To achieve the goal in the steam generator, which contains a housing with feedwater inlet pipes and steam outlet pipes, a casing installed in the housing, an annular channel for feeding water supply, equipped with vintonl-di fins, and an inlet pipe in the upper part of the housing fuel and oxidant, the lower part of the casing is made conical with central and peripheral rows of injection holes for the stitching species, with the axes of the holes of the peripheral mountain located 45 parallel to the axis of the housing and the price axes ral- Foot row - with a slope to the last,

FIG. 1 shows a steam generator; FIG. 2 is a sectional view of FIG. t,

The llaiDoreHepaTop comprises a housing 1c 50 with patches 2 and 3 for supplying feed water and steam removal, respectively, a casing 4 forming with wall I

an annular channel 5, equipped with screw ribs 6. In the upper part of the housing 1 there are nozzles 7 and 8 for the supply of fuel and oxidizer, respectively. The lower part 9 of the casing 4 is made conical with central and peripheral rows of openings 10 and 11, respectively, for the injection water. The axes of the holes in the peripheral radius are parallel to the axis of the steam generator, and the central ones are inclined to the latter. A spark plug 12 is installed in the upper part of the housing 4.

The steam generator works as follows

Through the nozzles 7 and 8 of the fuel supply and the oxidizer, hydrogen and oxygen gases flow into the steam generator, forming an explosive mixture ignited by the ignition plug 12. The feed water is supplied through the feed-water supply pipe 2 and moves down the annular channel 5, cooling the steam generator (the flame temperature at the center of the torch reaches 3000 ° C). Through the openings 1O and 11, the feed water is injected into the inside of the casing 4. The openings 11 are directed oppositely to the fuel nozzles 7 and 8 and are close to the inner surface of the casing 4, therefore the water coming out of the openings 11 is trickled down and cools the inner surface flame torch.

Holes 1O directed under the axis of the steam generator. This arrangement of the holes forms a cooling zone directly at the nozzle 3 for the removal of steam, which will ensure its protection from temperature destruction, and thus increase the reliability of the device as a whole.

At the same time, the steam generator will work (steadily, if the temperature of the feed water before injection is 20100 ° C below the vaporization temperature

The presence of the conical part. 9 housing with a central and peripheral rows of holes 10 and. 11 allows to increase the reliability of the steam generator as a result of the organization of effective cooling of its elements.
