Description

WATER HEATING BOILER

The utility model relates to heat engineering and can be used for water heating and heating various liquids.

A water heating boiler is known that contains a casing in the form of a vertical water jacket, a firebox with a grate, an ash-pan and a furnace door located opposite the corresponding openings made on the front side of the casing, a chimney pipe, a pipe for supplying air to the ash-pan zone and pipes for water discharge and supply ( RF patent No. 2068158, IPC F 24 H 1/26, publication October 20, 1996).

A disadvantage of the known boiler can be seen in the fact that the boiler has a complex structure and is not economical enough, because there is no way to control the process of burning fuel.

The task to which the utility model is directed is to create a water heating boiler with a simple design, capable of operating on various types of fuel and having high efficiency.

The problem is solved due to the fact that in the well-known boiler, containing a casing in the form of a vertical water jacket, a firebox with a grate, an ash-pan and a furnace door located opposite the corresponding openings made on the front side of the casing, a chimney, a pipe for supplying air to ash zone and pipes for water drainage and supply according to the task to be solved, the water jacket consists of two coaxial pipes of rectangular cross section, with the height of the inner pipe of a smaller height of the outer, pr the lower ends of the pipes are connected by a rectangular sheet made with a rectangular cut matching the inner rectangular pipe, and the upper ends of the pipes are closed with the corresponding rectangular sheets made with coaxial holes for the chimney, and the pipe for supplying air into the ash zone is connected to the opening made on back of the case.

In particular cases of implementing a utility model, a water boiler can be equipped with a fan, a valve with an electromagnet for opening this valve, mounted on a pipe for supplying air to the ash zone, and the first sensor F 24 N 1/26

temperature switch, the control output of which is connected to an electromagnet. In addition, the water boiler can be equipped with electric heaters located inside the water jacket, an electromagnetic starter to start the electric heaters, and a second temperature switch-sensor, the control output of which is connected to the electromagnetic starter, while the electric heaters are attached to the inner surface of the rectangular sheet covering the outer pipe.

A utility model is illustrated in the drawing, where in FIG. 1 is a view of the rear panel of the boiler.

In the drawing are indicated:

1- Water heating boiler;

2- Temperature sensors;

3- Pump-action relay;

4- Electromagnet;

5- Distribution block;

6- Transformer;

7- Electromagnetic starter;

8- Electrical panel;

9- Air supply valve; 10,11,12 - Spare fittings; 13 - circulation pumps;

14, 15 - Outlet and inlet pipes of hot water circulation.

The water heating boiler is made in the form of a rectangular cabinet 1. On the front side of the boiler there are ash and fire doors (not shown in the drawing). On the rear side behind the removable panel there is a pipe with a valve 9 for supplying air to the ash zone with a fan and valve installed on it, as well as an electromagnet 4 for opening these valves, temperature sensors 2, distribution block 5, electromagnetic starter 7 for starting electric heaters, two pipes 14 and 15 with a pipe thread for supplying and discharging water, a plug for draining water and an earthing bolt. On the upper side of the boiler there is a chimney of square cross section, four eye bolts, as well as a filler neck.

The boiler includes the following components: base, body 1, two doors (ash and fire), grate, removable rear panel, cladding and thermal insulation.

The welded body is made of carbon steel. It is a vertical water jacket formed by two coaxial pipes of rectangular cross section, with the inner pipe shorter than the outer one. The lower ends of the pipes are connected by a rectangular sheet having a rectangular cutout coinciding with the inner rectangular pipe. The upper end of the inner rectangular pipe is closed by a sheet with a square window into which a chimney is welded. Inside this rectangular pipe there is an ash-pan space and a firebox. The upper ends of the rectangular pipes are closed with rectangular sheets (roofs) having coaxial windows through which a chimney welded to both sheets passes. In addition, in the outer roof there are holes in which the filler neck is welded and 3 electric heaters are inserted. Outside, bent channels are welded to the body for fastening the cladding. All welds of the body are available for inspection and repair. From the side of the water jacket, the body walls have stiffeners.

Ash-pan doors and furnaces are double, in addition, they are equipped with a reflective screen to reduce the temperature of their outer surface. Tight locking of the doors is ensured by wedge closure. In addition, the cut of the doorway and the door itself form a labyrinth seal.

The housing is installed through the gasket on the base. The base is a frame welded from channels. The bottom and top frame is closed with sheets and filled with insulation. Three racks are welded from above to the frame, on which the grates are mounted. The body is covered with mineral wool insulation.

Outside, the boiler is covered with a decorative cladding of thin steel sheet. Facing has a color protective and decorative coating. The lining can also be made of galvanized sheet. Doors are covered with heat-resistant enamel.

On the back side of the boiler lining there is a quick-detachable hatch through which access to temperature sensors-relays 2 and to executive equipment is provided. Temperature sensors-relays 2 are used to maintain a given temperature of the water leaving the boiler.

The set of essential features of the proposed water boiler allows you to implement its work in a controlled smoldering mode. Stuffed fuel is in a state of decay, i.e. minimum (economical) fuel consumption is provided. If necessary (for example, when the ambient air temperature drops below a predetermined one), the blower fan is turned on and the smoldering process goes into intensive combustion mode, which leads to a sharp increase in heat transfer. When the solid fuel boiler is operating, the principle of its operation is as follows:

-with the help of a temperature sensor-relay, the value of the temperature of the water leaving the boiler is set, while another temperature sensor-relay controlling the electromagnetic starter of electric heaters is in the off position.

- if the actual water temperature is lower than that set on the temperature sensor relay, then an electromagnet is triggered, which opens the valve of the pipe supplying air to the ash zone, and the fan, which turns on.

-thanks to the natural draft and air pressure created by the fan, in the ash zone, the flame flames up and heat generation increases sharply;

- after the water temperature at the outlet of the boiler reaches the value set by the temperature controller, the electromagnet and the fan are turned off and the valves are closed;

- the air supply to the ash zone stops and the flame extinguishes, while the heat generation decreases;

-After the water temperature drops below a predetermined cycle repeats.

At the same time, solid wood can be used, including wood chips, bark, sawdust and other waste from woodworking production. In many cases, this solves the problem of the disposal of such waste.

When the boiler is operating from the mains, the principle of its operation is similar, with the exception that the electromagnet and fan are not triggered, but the electromagnetic starter 7, which includes the electric heating elements.

The possibility of the boiler operating on solid fuel and / or electricity allows the consumer to choose the most favorable conditions for the operation of the boiler.
