WATER BOILER

The proposed utility model relates to a power system and heat engineering, in particular, can be used in boilers operating in heating systems and hot water supply.

Known water tube boiler (see patent No. 2126937, IPC 6, F24H 1/00, publ. BI No. 6 02/27/1999), containing, the furnace, lower and upper screens, convective heating surface, and a partition between the furnace and convective surface, which located vertically and connects the ends of the pipes of the lower and upper screens, and the partition is fixed in the pipes of the lower screen.

However, such a boiler has a high energy intensity and cost, inconvenient to maintain.

This disadvantage is due to the complex layout of the known boiler.

Closest to the claimed one is the prototype of a hot water boiler (see patent No. 2130047, IPC 6 F24H 1/00, publ. BI No. 25 09/10/1999), containing a sealed enclosure filled with water, inside which there is a fire chamber and smoke tubes equipped with heating elements installed with a gap, one end of the pipe of which is connected to the water volume of the boiler, and each heating element is wound from a smooth pipe

F24H 1/00 screw coil inserted into the smoke pipe to form

spiral channel, while the second end of the pipe of the heating elements is connected to the feed pipe.

A disadvantage of the known hot water boiler is low reliability and heat utilization of burnt fuel and high energy intensity.

This disadvantage is due to the design features of the known boiler, which entail low intensification of heat transfer and the absence of an explosive valve.

The technical result provided by the utility model is to increase the reliability and use of heat of burnt fuel and reduce energy intensity and cost.

This result is achieved by the fact that in a known hot water boiler containing a sealed enclosure including a fire chamber and smoke tubes, front and rear tube boards, cavities for the passage of flue gases, according to a utility model, equipped with nozzles for supplying and discharging heated water, the boiler body is made in the form a heat-insulated cylinder placed in a rectangular frame made of a metal profile closed by a decorative casing, mounted on a frame base, the heat chamber is equipped

explosive valve, and smoke tubes installed in tube tubes fixed in the housing are equipped with swirls and are connected by outlet sections to the front and rear cavities for the passage of flue gases,

formed, respectively, by the front and rear covers and the front and rear tube plates, the rear cavity for the passage of flue gases connected to the gas duct for exhaust gases, which is mounted on the rear cover of the boiler, the decorative casing is made of panels, and the heat chamber is equipped with an inspection hole while the housing additionally contains a drain pipe, the water supply pipe is equipped with a diffusion plate, and mineral wool is used as a heat insulator

Between the distinguishing features and the achieved technical result, there is the following causal relationship.

In contrast to the known analogues and prototype, the use of a boiler in the proposed utility model, which is made in the form of a thermally insulated cylinder, placed in a rectangular-shaped frame made of a metal profile, closed on a frame, mounted on a frame base, makes it possible to rationally use the place of its installation and transportation, because . it becomes possible to stack the boilers on the side surfaces, in addition, equipping the fire chamber with an explosive valve increases the reliability and durability of the boiler, and supplying smoke tubes with swirlers and a water supply pipe with a diffusion plate ensures a rational

use of heat of burnt fuel.

technology, which allows us to conclude that the claimed object meets the criterion of novelty.

The set of essential features characterizing the essence of the utility model can be repeatedly used in the production of various modifications of hot water boilers to obtain a technical result consisting in increasing the reliability and use of heat of burnt fuel and reducing energy intensity and cost, which allows us to conclude that the claimed utility model meets the criterion " industrial applicability.

The essence of the utility model is illustrated by an example of a specific implementation:

- General view of the boiler - Fig. 1;

the flue gas movement diagram - figure 2;

The hot water boiler contains a sealed housing 1, which is made in the form of a thermally insulated cylinder placed in a rectangular frame made of a metal profile closed by a decorative casing. The boiler body 1 contains a fire chamber 3 and smoke tubes 4, mounted on the front 5 and rear 6 tube boards. The front and rear tube boards 5, 6 form with the front 7 and rear 8 housing covers, respectively, front 9 and rear 10 cavities for the passage of flue gases. The boiler body is equipped with nozzles for supply 11 and drain 12 of heated water. The boiler body is installed on a frame base 13. The heat chamber 3, the body is equipped with an explosive valve 14 and an inspection

hole 15. In the tube boards 5 and 6 fixed in the housing, are installed

smoke tubes 4, which are equipped with swirls 16. The rear cavity 10 for the passage of flue gases is connected to the flue gas duct 18, which is mounted on the back cover of the boiler 8. The decorative casing is made of panels 19. Mineral wool is used as a heat insulator 20 in the boiler body. The housing further comprises a drain pipe 21 located in the lower part of the housing. The inlet water pipe 11 is equipped with a diffusion plate 22. A heat source, such as a burner (not shown in the drawing) provides due to the powerful torch 23 the normal operation of the boiler.

The boiler operates as follows.

The torch torch 23 is located horizontally in the center of the flame chamber 3. The flue gases, reaching the end bottom of the flame chamber 3, swirl and rotate 180 ° and enter the front cavity 9 for the passage of flue gases, and from there they enter the smoke tubes 4 with swirls 16, through which pass into the rear flue cavity 10, and then into the flue gas duct 18 for exhausting gases from the boiler and enter the boiler chimney (not shown in the drawing). In parallel, cold water is supplied through the inlet of the heated water 11 and is mixed with the hot water in the boiler using a scattering plate 22. Hot water from the boiler is discharged through the outlet pipe of the heated water 12.
