Description

WATER BOILER

The utility model relates to a power system and can be used in boiler building.

The closest in technical essence to the proposed device is a hot water boiler containing a grate for fuel, a device for supplying fuel to the furnace, side screens, an intermediate gas-tight wall, a convective beam, and windows for the passage of gases formed by bending part of the pipes of the gas-tight wall in the plane parallel to the screens, as well as an ash bin. (see .. A.S. USSR, No. 305312, class F24H 1 / 00.1971).

As a result of the analysis of the design of the well-known hot water boiler, it should be noted that a large number of expensive lining materials are used for its manufacture, which increases the cost of boilers, and in addition, excessively increases the mass of boilers. The bead-blowing system used on these boilers for cleaning convective surfaces can lead to damage and does not provide effective cleaning of convective surfaces.

The objective of this utility model is to develop a design of a relatively small mass hot water boiler with a reduced content of expensive lining materials and with an effective system for cleaning convective surfaces.

IPC F24H1 / 00 block, separated from each other by a dividing element with a window in

the upper part, the device for supplying fuel to the combustion chamber, and the ash hopper mounted at the bottom of the convection unit, new is that the device for supplying fuel is made in the form of a gas-oil burner installed on the front wall of the boiler, the dividing element and the rear wall of the boiler are made shielded, moreover, the boiler is equipped with a gas-pulse system for cleaning convective surfaces, which consists of exhaust pipes connecting pulse chambers to the boiler, which are connected through air gates ki, ignition system assembly and valve control unit with an electromagnetic drive.

The utility model is also characterized by the fact that the separation

the element is gas tight.

This allows you to refuse to install the wall of the lining materials between the combustion chamber and the convection unit, which means to save the lining materials ..

When conducting patent research, no solutions were found that are identical to the declared one, and therefore, the claimed utility model meets the criterion of “novelty.

We believe that the information presented in the application materials is sufficient for the practical implementation of the utility model.

The essence of the utility model is illustrated by graphic materials, where

In Fig.1 shows a boiler in a section;

Figure 2 presents a diagram of a gas-pulse system for cleaning convective surfaces

The hot water boiler is made in the form of a single unit that combines the combustion chamber 1 and the convection unit 2.

A gas-oil burner 3 is mounted on the front wall of the boiler, to which the fuel and gas supply lines are connected (not indicated by positions).

The separation element 4 between the combustion chamber 1 and the convective part 2 is made shielded, and in the upper part has a window 5, closed by a gas-permeable wall 6.

The separation element 4 can be made gas tight.

The rear wall 7 of the boiler, as well as element 4, is shielded.

In the lower part of the convection unit 2, an ash bin 8 is made.

The output of the combustion products is carried out through the window 9 in the lower part of the rear wall 7.

To clean convective surfaces from external deposits formed during combustion in a fuel boiler, a gas-pulse cleaning system is used, made in the form of exhaust pipes 10 connecting pulse chambers 11 to the boiler, which are connected through air valves 12, the ignition unit 13 to the system control unit 14, and valves 5 with an electromagnetic actuator (to hell not showing.).

The collectors (to hell, not shown) that are part of the system are designed to distribute the gas-air mixture to the pulse chambers using valves 15 with an electromagnetic actuator and a control unit for the system 14.

At the same time, the system control can be either automatic or manual.

The hot water boiler operates as follows.

To ensure the operation of the boiler, ignite the fuel (a mixture of gas and fuel oil) supplied by the burner 3 to the combustion chamber 1. The fuel burns in the combustion chamber 1. Under the influence of the draft, the flue gases rise upward and pass through the window 5 into the convection unit 2, by which make a downward movement and are removed from the boiler through the window 9 of the rear wall 7. When moving, the flue gases heat the pipes with

water in them.

Unburned fuel particles fall into the ash bin 8.

If necessary, cleaning convective surfaces put in place a gas-pulse cleaning system.

Before switching on gas-pulse cleaning, the air supply pipelines and impulse chambers And are blown with air by opening the air valves 12. Open the shut-off valves 16 for supplying gas to the line, turn on the control unit 14, and set the necessary pulse frequency. Open the solenoid valve 15. On the manometer 17 set the minimum gas pressure at which explosive combustion of the resulting air-gas mixture occurs.

The necessary air pressure is maintained by a pressure gauge

Using the spark plug / $ installed on the ignition unit, they ignite the gas-air mixture, and a flame is formed, which propagates through the mixture line to the pulse chamber 11 and the nozzle block (to hell, not showing.) Then the mixture explodes. Then, through the exhaust pipes 10, the products of explosive combustion and the shock waves created thereby are transmitted to the surface to be treated.

Pulse chambers 11 are installed either on the service site or on the convective part of the boiler.
