Description

U j Uiivi IIwi.iJllI / 1 / i Illu-iiljLi ilUj.Ijji.

The utility model relates to heat power engineering, in particular to small heat power engineering facilities, and more specifically, it is not enough to design hot-water boilers:. and average power intended for heating residential premises and buildings, as well as for receiving hot water for domestic needs.

/ is known for heating water heaters: a boiler, containing: a di-cabinet, a firebox with gerelko / g, a heat exchanger, inlet and outlet pipelines and a gas duct / see A.S. // bo, publ. J. 4 C.G.).

The design of this boiler makes it possible to increase the specificity of the installation by increasing the heat exchange surface of the boiler due to the special connection of the heat exchanger section.

However, the name :; and complicates to a large extent the design of this boiler, making it moreover quite difficult-- to maintain.

the heater is known --.- ng water-heating boiler, selected as a close-up ana ..; aha, containing a housing with pipes for supplying cold and exhaust hot water and exhaust gases, equipped with the following: cutting; about a combustion chamber with a burner mounted on the bottom - its parts, the heat exchanger and, installed from the flues, turbulizers in its upper part

/cm. patent iu, class.all II i / 14, publ. 2C.II.9dr. / r, the same design, despite its advantages / increased economic n: indicator: /, versatility / availability of a cooker with a cooking table for cooking / and the ability to work on various fuel fuels, it remains quite difficult and material-intensive due to the presence of, in particular, a decorative casing and additional: structural elements, ensuring that the boiler operates on different types of fuel - grate, evenly. doors, .itka, boot shaft covers to the like, which is the result. maintenance and operation of this boiler.

1 In addition, the design of the turbulator and its installation in the inter-turn spaces of the gas duct contributes to the intensive wear of their products: burned down and reduced the efficiency of the apparatus.

hakim way, those: n: the result that is not right for the solution: a useful model is to simplify co-production and, as a result, increase its reliability, as well as reduce the material consumption of the boiler and increase the efficiency of its operation.

In addition, d ps.: The tangible technical result achieved with the help of the applicants is claimed to be useful, the model is the expansion of the assortment of produced heating water heaters.

“The indicated technical results are achieved by the fact that in a known heating water heater. Mr. boiler, we will contain the case with branch pipes of a supply of cold and removal of hot water and exhaust gases, equipped with a water jacket 1 about -

the combustion measure with the burner is limited to: its parts, the heat exchanger installed in the flues, turbulators in the upper part, according to the utility model, the combustion chamber is additionally equipped with a baffle made on its rear wall opposite the burner and non-stationary installation: g fireproof a partition located with a gap above the divider and forming the upper part of its rear wall, the heat exchanger is made in the form of sections arranged with gaps forming gas ducts, interconnected, and turbulators are installed on Nome on each side of each duct and represent esboP flat sheets vyshtampovki provided with a plurality of bent flakes staggered, with each subsequent cheschuek bent towards predkduscheG on the opposite side of the sheet.

The supply of the combustion chamber with a divider made on its rear wall opposite the burner provides not only a change in the direction of the flow of hot gases, which improves heat transfer and, consequently, increases the efficiency of the installation, but also eliminates overheating of the rear wall of the combustion chamber and its burn through, which ensures an increase reliability of the boiler design.

At the same time, the design of the divider is so simple that it does not complicate the design of the boiler as a whole.

The supply of the combustion chamber of a non-stationary mounted refractory partition, located: with a gap above the divider and forming the upper part of its rear wall, significantly simplifies the design of the boiler. This is achieved due to the fact that this partition during repair

or brushing is freely removed, providing a good access to the combustion chamber, and is also easily installed in place.

In addition, such an arrangement of the partition, namely, its installation with a gap ll above the divider and the fact that it forms the upper part of the rear wall of the combustion chamber,

contributes to increased efficiency of the boiler. This is due to the fact that this partition: aUsgormiruet wall

the combustion chamber, but also one of its flues, and the step formed by the thickness of this partition also contributes to a change in the direction of the gas flow, reinforcing the role of the divider.

All these design features contribute to the improvement of heat transfer and, as a result, increase the installation efficiency, while not only not complicating the design of the boiler, but rather simplifying it, which significantly increases its reliability.

The implementation of the heat exchanger in the form of sections interconnected with gaps forming gas ducts also helps to increase the efficiency of the device by increasing heat transfer.

The installation of turbulators on each side of each gas duct and their implementation in the form of flat sheets with a lot of vyshtumuvok - bent flakes arranged in a checkerboard pattern, with the bending of each subsequent cauldron relative to the previous on the opposite side of the sheet, increases the heat transfer coefficient, which is achieved due to more significant mixing of the flow of hot gas.

Moreover, this embodiment and arrangement of turbulators provides a significant reduction in the temperature of the exhaust gases.

not just.

In addition, their implementation and location, simplifies both their manufacture and maintenance, and also helps to retain particles of combustion products, which positively affects the environment.

The set of essential features of the claimed object of the device is different from the closest analogue, therefore, meets the criterion of novelty.

semolina coin design is widely used in mechanical engineering, in particular in boiler building, which testifies to its industrial applicability.

The essence of the useful model is illustrated by drawings.

The gas-fired heating water boiler includes a housing 1, a cold water supply pipe гер, and a hot water outlet. water 3 and exhaust gas 4, a combustion chamber b, equipped with a water jacket G, a burner /, a heat exchanger and turbulators b.

The heat exchanger is made in the form of interconnected sections 9 located with gaps that normalize the flues 10. In each of these flues 10, one turbulator is installed on each of its sides, each of which is flat. sheet with stampings in the form of bent flakes II.

Section 9 of the heat exchanger is connected between itself and a water-1 jacket / o from pipelines 12.

On the rear wall 13 of the combustion chamber, a divider .14 is made. Freck divider: / A at a distance of approximately tvj mm there is a non-stationary mounted refractory partition 1L made of vermiculite, which feeds the upper part of the rear1 / wall 13.

The device operates as follows.

Fuel (gas or diesel) is burned / in the combustion chamber o. the flow of hot gases moving along the combustion chamber reaches the rear wall 13, where the divider 14 is disconnected into two streams and dramatically changes its direction. By the gas ducts 16 and 17 formed in the combustion chamber L, and then by the gas ducts 10 formed by the gaps between the heat exchanger sections 9, hot gases, giving off heat to the water jacket t and the heat exchanger sections 9, are discharged through the exhaust gas outlet 4.

Punching in the form of cases Ii, II, made on turbulators b not only gives the exhaust gas flow a direction, but also improves the heat transfer conditions by increasing the heat transfer coefficient, while significantly reducing the temperature of the exhaust gases.

Cold water enters the boiler through pipe 2, and hot water is discharged from the boiler through pipe 3.
