Water boiler (options). The technical field to which the utility model relates.

The utility model relates to a power system and can be used in devices for heating water.

State of the art

A well-known hot water boiler (see patent No. 2032858, IPC. F24H 1/26, publ. 04/10/1995, bull. No. 10), containing a body equipped with a water jacket with an exhaust pipe, a furnace with doors and a blower chamber, transverse and longitudinal screens, connected by water to the jacket, the latter being connected by water to the jacket of the body in its ceiling part with the formation, together with the transverse screen, of a system of convective flues located in one vertical transverse plane The disadvantage of this boiler is the design of the duct, in which The natural draft of hot gases is very small, which does not allow to maximize heat transfer and reduces the reliability of the boiler.

The closest constructive solution to the claimed utility model selected for the prototype is a hot water boiler placed in the volume of the heating furnace (see copyright certificate No. 370418, IPC: P24C 13/00, publ. 15.11.1973, bull. No. 11), and comprising a housing provided with a water jacket, in which a furnace with doors and a blower chamber are located, and vertical screens forming a U-shaped duct, screens connected by water to the side walls of the housing jacket. However, there is no water jacket in the ceiling of the casing of such a boiler, which results in low efficiency of such a device.

Utility Model Essence

The claimed utility model solves the problem of increasing the efficiency of the boiler by increasing the heating surface.

The problem is solved in that in a heating boiler containing a casing provided with a water jacket, including a firebox with doors and a blower chamber and transverse screens connected by water to the side walls of the casing jacket and forming a U-shaped duct, communicated at the outlet with an exhaust pipe, according to the first embodiment of the utility water model

the shirt is made covering the ceiling of the housing and one of the screens is connected with the jacket of the housing in the ceiling. According to the second embodiment of the utility model, the ceiling part of the case is made in the form of a set of pipes parallel to each other located in the same horizontal plane close to each other, with end parts connected through water to the side walls of the jacket of the case.

Both versions of the inventive hot water boiler solve the same problem of increasing efficiency, including efficiency and reliability of the device, essentially the same way - by maximizing the heating surface.

The claimed technical solutions differ from the prototype by the presence of a water jacket in the ceiling of the housing, which allows us to conclude that the technical solutions meet the criterion of "novelty.

In special cases of the execution of the second embodiment of the utility model, an additional technical result can be obtained, namely: coating the ceiling of the boiler body with heat-insulating lining can reduce heat loss to the atmosphere, which leads to a decrease in specific fuel and energy costs.

In order to prevent deformation of the boiler body, both in the first and second versions, the inner and outer walls of the jacket are interconnected by arbitrary stiffeners.

Information confirming the feasibility of implementing a utility model

Kyu JO & SG &

equipped with two transverse screens 8 and 9, connected by water to the side walls of the jacket 1 of the housing and forming a U-shaped duct 10, communicated at the outlet with the exhaust pipe 11. In the ceiling part of the housing according to the first embodiment (see Fig. 1-3) is made cooking hole 12. According to the second option (see Fig. 46), the ceiling part of the body is made in the form of a set of pipes 13, with end parts connected by water to the side walls of the shirt 1 of the body. The casing is covered with a heat-insulating lining at the top 14. A hole with a door 15 is provided in the casing for the preventive cleaning of the duct 10.

The inventive hot water boiler operates as follows.

After ignition of solid fuel, pre-loaded through the door 3 to the grate 7, the gases from the furnace 5 through the duct 10 and exhaust pipe 11 go into the atmosphere. In this case, hot gases from the furnace 5 wash the ceiling part of the body and the transverse screens 8.9 associated with the jacket 1 of the body and give off thermal energy to the water in the water jacket 1 of the boiler. The execution of the ceiling part of the boiler in the form of a combination of pipes 13 located parallel to each other in the same horizontal plane 13 increases the heating surface even more, and the heat-insulating lining 14 reduces heat loss. The door 4 is intended for cleaning the blower chamber 6 of ash.

The implementation of the water jacket covering the ceiling of the housing allows you to maximize the convective heating surface, which leads to increased efficiency and reliability of the boiler.
