Description

The utility model relates to heating devices intended for heating water for household and/or domestic needs and use in heating systems, namely to long-burning solid fuel hot water boilers, and can be used in space heating systems.

The closest to the claimed utility model is a long-burning hot-water solid fuel boiler (RU Patent No. 153177, IPC F23B 60/00, published on 10.07.2015, Bulletin 19), which contains an outer casing, a vortex-type combustion chamber connected to the casing, a chimney connected to the combustion chamber, an ash pan with a grate, and pipes made in the outer casing with the ability to pass water inside and from the cavity filled with water. This boiler is selected as a prototype of the claimed utility model.

The disadvantages of the prototype boiler are as follows. The absence of an ash pan as a separate removable element, but the presence of a grate, which complicates the operation of the boiler: to clean the boiler from fuel residues, it is necessary to dismantle the grate through the side door and only then remove the ash. The presence of a complex system for supplying and effectively distributing air inside the combustion chamber, made in the form of a telescopic pipe, the lifting and lowering of which is carried out using a cable through a block of rollers with a diffuser at the end. This air supply system is difficult to automate, which makes the process of controlling boiler combustion "manual". The presence of thermal insulation of the boiler bottom, made of fireclay or red brick, which increases the weight of the boiler. The absence of an additional ash removal system on the flue gas outlet tract, which generally reduces the environmental performance of the boiler.

The technical result of the utility model is the creation of a hot-water solid fuel boiler with long burning and improved fuel combustion efficiency, due to the presence of a diffuser made in the form of a water-filled pipe located inside the combustion chamber, under the neck, with the possibility of dosing the fuel flow coming from the fuel bunker under the action of gravity into two cones (left and right).

The stated technical result is achieved by creating a long-burning hot-water solid fuel boiler containing:

outer casing 1, made in the form of a vertical cylinder, with the possibility of ensuring external tightness of the water jacket;

a vortex-type combustion chamber 2, which is connected to the outer housing 1 and to the air duct pipe 3, configured to connect an air turbocharger 14, which is connected to the electronic control unit 15 and configured to supply air to the combustion chamber 2 through the air duct pipe 3;

a chimney 5, which is connected to the combustion chamber 2 and is designed with the possibility of connecting a smoke pipe 12;

fuel bunker 7, which is connected at the bottom to the neck 6 of the combustion chamber 2, and at the top has a hatch 19 for loading fuel;

a diffuser 11, made in the form of a water-filled pipe located inside the combustion chamber 2, under the neck 6, with the possibility of dosing the fuel flow coming from the fuel bunker 7 under the action of gravity into two cones (left and right);

inlet and outlet pipes 9 and 10, made in the outer casing 1 with the possibility of passing water into and from the inside of the cavity filled with water, located between the outer casing 1 and the combustion chamber 2, the chimney 5, the fuel bunker 7, the diffuser 11.

In a preferred embodiment of the boiler, the combustion chamber 2 of the vortex type is made in the form of a horizontal cylinder, on the bases of which at least one door 4 is made with the possibility of igniting the fuel through it, as well as with the possibility of removing the remains of unburned fuel through it, in the absence of an ash pan.

In a preferred embodiment of the boiler, the chimney 5 is reinforced with transverse water-filled pipes 8 connected to the outer casing 1.

In a preferred embodiment of the boiler, the smoke stack 12 is designed with the possibility of installing on it an axial cyclone filter 13, designed with the possibility of cleaning the flue gases from ash.

In a preferred embodiment of the boiler, the fuel bunker 7 is made in the form of a vertical cylinder, the lower conical part of which is connected to the combustion chamber 2 by a neck 6, and the upper part has a hatch 19 for loading fuel.

In a preferred embodiment of the boiler, the outer casing 1 is covered along a cylindrical generatrix with thermal insulation 16, made in the form of stitched mats of mineral wool with a foil coating, as well as under the bottom and on the top cover, and the remaining parts are covered with thermal insulation paint, while the outer casing 1 is covered with an easily removable decorative casing 17, and has mounting legs 18 at the bottom.

Let us consider the embodiment of the declared long-burning hot-water solid fuel boiler (Fig. 1-3). The hot-water (steam) long-burning solid fuel boiler consists of

outer casing 1 – a cylindrical shell that ensures external tightness of the water jacket;

combustion chambers 2 of the vortex type (horizontal or vertical design), air supply to which is carried out tangentially through the air duct pipe 3, combustion chamber 2 is locked by two doors (or one door) 4;

ash pan (optional, depends on modification);

a chimney 5, reinforced with transverse water-cooled pipes 8, with a smoke pipe 12, on which an axial cyclone filter 13 for cleaning flue gases from ash is installed;

fuel bunker 7, which is connected to the firebox by a neck 6;

inlet and outlet pipes 9 and 10, through which the flow of water through the boiler is organized.

An air turbocharger 14 is installed on the air duct 3, connected to the electronic control unit 15, and is made removable, for the possibility of its maintenance and replacement. Fuel is loaded into the fuel hopper 7 manually through the fuel loading hatch 19. Fuel is ignited through the door 4 of the combustion chamber with a portable gas burner. Residues of unburned fuel (in case of a sudden stop of the boiler) are also removed through the door 19 of the combustion chamber 2. An option is possible when an ash pan with its own tank for accumulating residues of unburned fuel is connected to the combustion chamber 2. The outer casing is covered with thermal insulation 16 (stitched mineral wool mats with a foil coating) along the cylindrical generatrix, as well as under the bottom and on the upper wall to reduce heat losses to the external environment, on the remaining surfaces, which it is not technologically feasible and practical to cover with thermal insulation material, thermal insulation paint is applied to prevent contact with heated surfaces. The thermal insulation is covered with a protective, easily removable decorative casing 17. The outer casing 1 of the boiler is installed on adjustable legs 18 with an anti-slip coating that allow the boiler to be installed at floor level.

The declared hot water solid fuel boiler of long burning has a simpler design, including a simpler design of the air supply and distribution system, and less weight, due to the absence of an ash pan with a grate.

Although the above-described embodiment of the claimed utility model was set out for the purpose of illustrating the claimed utility model, it is clear to specialists that various modifications, additions and substitutions are possible that do not depart from the scope and meaning of the claimed utility model, disclosed in the attached formula of the utility model.
