Description

The utility model relates to heating equipment and can be used in the manufacture of heating gas boilers for domestic and industrial purposes.

Known gas heating boilers are made both with a horizontal arrangement of the chimney outlet (or otherwise - the chimney) (see, for example, a patent for a useful model UA 75567, M.cl. F24H 1/00, publ. 10.12.2012), and with vertical arrangement of the chimney outlet (see, for example, patent for a useful model RU 98548, M. class F24H 1/00, publ. 20.10.2010).

Boilers with a vertical chimney outlet are most often used in houses with a vertical chimney passing through the ceiling of the house. Such boilers make it possible to equip boiler rooms both in the basement and in the basement.

Boilers with a horizontal position of the chimney outlet (chimney) make it most easy to bring the chimney out through the wall of the house using a horizontally located chimney.

In residential and other buildings, heating boilers can be used both with a horizontal arrangement of the chimney outlet, and with a vertical arrangement of the chimney outlet.

If it is necessary to replace a gas heating boiler with a new boiler, as a rule, use a boiler with a similar location of the chimney outlet, that is, horizontal or vertical, respectively. This allows the new boiler to be quickly connected to the existing chimney at the lowest cost.

The closest analogue to the claimed boiler is "Floor-standing gas boiler ATEM ZHITOMIR 3 KS-G-20 SN" (see https://nash-dim.net/p582446920-gazovyj-kotel-napolnyj.html). The known boiler contains a metal body, a combustion chamber, a fire-tube heat exchanger with convective heating surfaces, a draft interrupter with a chimney branch pipe, which is inseparable from it. The boiler is produced in two modifications: with a vertical chimney branch pipe and with a horizontal branch pipe. For each modification of the boiler, use its own draft breaker, respectively, with a vertical or horizontal chimney branch pipe. Therefore, the production of boilers of two modifications requires the manufacture and use of two different design traction breakers.

The general essential features of the closest analogue and the claimed utility model are "A gas heating boiler, which consists of a metal body, a combustion chamber, a fire-tube heat exchanger with convective heating surfaces, a draft interrupter with a chimney outlet."

The disadvantage of this boiler, like all other known boilers, is that in the manufactured boiler its chimney outlet is inherently fixed to the draft interrupter and can only take one position: vertical or horizontal. Therefore, these boilers are produced in two versions (modifications) of execution: with a vertical chimney branch pipe and a horizontal chimney branch pipe.

The technical task of this utility model is the unification of the design of the gas heating boiler, due to which a boiler with a vertical position of the chimney outlet can be quickly and easily converted into a boiler with a horizontal position of the chimney outlet and vice versa.

The solution to the technical problem posed is achieved with the help of a gas heating boiler, which consists of a metal body, a combustion chamber, a fire-tube heat exchanger with convective heating surfaces, a draft interrupter with a chimney outlet pipe, in which, according to the utility model, the boiler draft interrupter contains a removable equal-shelf angular insert that covers on the outside there is a draft breaker in its upper and rear parts, on one shelf of which a chimney outlet is fixed on the outside, connected through an opening made in this shelf, with a draft interrupter, while a removable equal-angle corner insert is made with the possibility of its mounting and dismantling on the draft interrupter in any of the two working positions of the chimney outlet: both vertical and horizontal, depending on the need, in addition, the boiler contains an equal angle cover with a through hole for placing the chimney outlet, which can be closed from the outside t is a removable equal-flange corner insert and is made with the possibility of its mounting and dismounting on the boiler in any of the two working positions of the flue outlet in accordance with the location of the equal-flange corner insert.

The claimed set of essential features of the claimed boiler is not known from the existing state of the art, which confirms the novelty of the utility model.

Thanks to the specified set of features of the claimed utility model, both the possibility of using the same set of boiler components is achieved, both for the manufacture of a boiler with the required location of its chimney outlet (vertical or horizontal), and the possibility of a quick and fairly simple conversion of a boiler with a vertical position the chimney outlet to the boiler with the horizontal position of the flue outlet and vice versa.

The device of the proposed gas heating boiler is explained by the description below with links to the attached drawings, which show:

FIG. 9 shows a removable corner insert for the draft breaker of FIG. 6 in another spatial arrangement, in which the chimney outlet fixed on the insert is located vertically, side view;

FIG. 10 is a boiler draft interrupter with a horizontal chimney outlet, which corresponds to the position of the corner insert shown in FIG. 6;

FIG. 11 is a boiler draft interrupter with a vertically arranged chimney outlet, which corresponds to the position of the corner insert shown in FIG. nine.

FIG. 1 and FIG. 2 shows the inventive gas heating boiler 1 in two different variants of the location of its outlet chimney 2.

FIG. 3 shows a longitudinal section along A-A of the boiler shown in FIG. 1, which differs from the boiler 1 shown in FIG. 2 vertical arrangement of the chimney 2.

The inventive gas heating boiler 1 (Fig. 2) consists of a metal body 3, a gas burner device 4, a combustion chamber 5, a fire-tube heat exchanger 6 with convective heating surfaces, which contains inside ribbed vertical gas ducts 7 connected to the cavity of the thrust breaker 8.

The boiler 1 also contains a removable equal-flange corner insert 9 that closes the draft breaker 8 from the outside in its upper and rear parts. The shelves 10 and 11 of the corner insert 9 are located at right angles to each other and are made of the same size and with the same places for fastening to the draft breaker 8. On the shelf 10 of the corner insert 9, a chimney outlet 2 is fixed from the outside 2. A through hole is made in the shelf 10 of the corner insert 12, through which the chimney outlet 2 is connected to the draft breaker 8 when the corner insert 9 is mounted on the draft breaker.

Due to the specified design of the corner insert 9, it has the ability to mount and dismantle it on the draft breaker 8 in two working positions of the chimney outlet 2, both vertical and horizontal, depending on the need, as explained in FIG. 4 and FIG. 5 as well as FIG. 10 and FIG. eleven).

The boiler also contains an equal-flange corner cover 13 with a through hole 14 to accommodate the flue outlet 2, which closes from the outside a removable equal-flange corner insert 9, and, like the corner insert, made with the possibility of its mounting and dismounting on the boiler 1 in two working positions chimney outlet 2. (Fig. 1, Fig. 2, Fig. 4, Fig. 5).

For connection to the water heating system, the boiler 1 contains an inlet 15 and an outlet 16 for supplying cold water and removing hot water, respectively.

Due to the above implementation of the proposed boiler, it can be easily converted from the boiler 1 with a vertical arrangement of the chimney outlet 2 shown in FIG. 1 into a boiler with a horizontal chimney, which is shown in FIG. 2.

To do this, it is enough to remove from the boiler the equal-flange corner cover 13 and the equal-flange corner insert 9, as shown in Fig. 4, and then changing their position in space, as shown in FIG. 5, fix in this position the corner insert on the draft breaker 8, and put the corner cover 13 on top of the corner insert 9 and fix it in this position on the boiler 1. As a result, the boiler, which is shown in FIG. 1 will be converted into a boiler as shown in FIG. 2.

To operate the proposed boiler, its outlet chimney 2, which is mounted in an appropriate spatial position, is connected to the chimney of a building or structure, and its inlet and outlet pipes 15 and 16 are connected to the water heating system, and also connected to the gas supply network.

During the operation of the boiler 1, natural gas is fed into the atmospheric-type gas burner 4 with partial admixture of primary air. The combustion process of the gas-air mixture occurs in the gas burner device 4 and in the combustion chamber 5 with secondary air. The combustion products enter the ribbed vertical gas ducts 7 and, passing through them, give off heat to the fire-tube heat exchanger 6, and then through the draft breaker 8 and the exhaust chimney 2 and the chimney of the house are evacuated into the atmosphere.

The applicant made a prototype of a gas heating boiler and tested its operation in two variants of mounting its exhaust chimney. The results of the tests carried out confirmed the possibility of its industrial application. Both variants of installation on the boiler of the flue gas outlet 2 (Fig. 1 and Fig. 2) have shown the reliable operation of the boiler. In this case, the retrofitting of the boiler embodiment shown in FIG. 1 to the embodiment of the boiler shown in FIG. 2, and vice versa, it is carried out quite easily and quickly without using any additional parts of the boiler. Thanks to this, the unification of the declared gas heating boiler is achieved.
