Description

Dry Distillation Membrane Wall Boiler

technical field

The utility model relates to a dry distillation membrane wall boiler.

Background technique

The current domestic boilers are all horizontal grates, without a coal storage room. After the fuel is put in, all of them will participate in the combustion. The fire is not easy to control. At the same time, the supply is insufficient and the combustion is not sufficient. At the same time, one feeding can only burn for 3-6 hours, and special personnel are needed. The guards ignite the fire every day to clean the ash. At the same time, the grate of the traditional boiler is cast iron grate, the heat at the bottom of the combustion chamber is wasted, and the grate is easily damaged.

Contents of the invention

The purpose of the utility model is to provide a dry distillation membrane wall boiler.

Above-mentioned purpose realizes by following technical scheme:

A dry distillation membrane wall boiler, which consists of a furnace body, the furnace body is divided into a coal storage chamber, a combustion chamber and a rear flue through a membrane wall and a partition plate, and the The lower end of the membrane wall is connected to the water-cooled grate as an integrated structure, and a plurality of heat exchange tubes are respectively fixed on the upper and lower sides of the smoke exhaust section of the furnace body;

The upper part of the coal storage chamber of the furnace body is provided with a coal feeding port.

In the dry distillation membrane wall boiler, a water return port and a water outlet are opened on the side of the furnace body.

In the dry distillation membrane wall boiler, the water-cooled fire grate forms an included angle of 20°-30° with the horizontal plane.

In the dry distillation membrane wall boiler, an air inlet is opened on the side wall of the furnace body.

In the dry distillation membrane wall boiler, the furnace body is located at the front end of the combustion chamber and is equipped with a damper.

Beneficial effect:

1. The utility model is equipped with a combustion chamber and a coal storage chamber. The flame enters the flue downward along the water-cooled grate in the combustion chamber. The running path is long, which is conducive to heat absorption. After the fuel is burnt, the fuel in the coal storage chamber will slide down to the combustion chamber by itself. With the front and rear dampers, the combustion speed can be controlled. One feeding can burn for 20-30 hours, which can save manpower.

2. The waiting area under the coal storage chamber of the utility model is in a state of high temperature and oxygen deficiency, and the coal is dry-distilled into coke, which burns more fully, releases more heat than coal, and is smoke-free, energy-saving and environmentally friendly.

3. The utility model adopts a water-cooled fire grate, the flame burns reversely and downwards, the fire grate absorbs heat, and has a long service life.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model;

In the figure: 1, chimney; 3, coal inlet; 4, coal storage room; 5, partition; 6, damper; 7, combustion chamber; 8, upper furnace door; 9, water-cooled grate; Door; 11. Water outlet; 12. Air inlet; 13. Heat exchange tube; 14. Membrane wall; 15. Furnace body; 16. Water return port; 17. Base.

Detailed ways:

Example 1:

A dry distillation membrane wall boiler, which consists of a furnace body 15, the furnace body is divided into a coal storage chamber 4, a combustion chamber 7 and a rear smoke chamber by a membrane wall 14 and a partition 5. Road, the lower end of the membrane wall is connected to the water-cooled grate 9 as an integrated structure, and the upper and lower sides of the smoke exhaust section of the furnace body are respectively fixed with a plurality of heat exchange tubes 13;

The upper part of the coal storage chamber of the furnace body is provided with a coal feeding port 3 .

The membrane wall structure is used to increase the heating area of the water pipe, which can absorb the residual heat of the flame more effectively. The air inlets on both sides of the middle of the boiler are used in conjunction with the damper at the front of the combustion chamber to adjust the air intake and combustion speed to control the outlet water temperature. Effect.

The upper part of the furnace body is the chimney 1 and the water outlet 11, the upper furnace door 8 and the damper are arranged at the front end of the combustion chamber, the lower part of the water-cooled grate is the ash chamber, and the air inlet 12 is arranged above the rear of the ash chamber and above the heat exchange tube. A dust-cleaning furnace door 10 is arranged in the front of the body of furnace.

Example 2:

Example 3:

According to the dry distillation membrane wall boiler described in embodiment 1 or 2, the water-cooled grate forms an included angle of 20°-30° with the horizontal plane.

Example 4:

According to the dry distillation membrane wall boiler described in embodiment 1, 2 or 3, an air inlet 12 is opened on the side wall of the furnace body.

Example 5:

According to the dry distillation membrane wall boiler described in embodiment 1 or 2 or 3 or 4, the furnace body is located at the front end of the combustion chamber and is equipped with a damper 6, which is a commonly used air regulating structure for boilers.

Working principle: The combustion chamber and coal storage chamber are set up, the coal is fed through the coal inlet, the flame enters the flue downward along the water-cooled grate in the combustion chamber, the running path is long, which is conducive to heat absorption, and the water-cooled grate is 20-30 ° included angle, after the fuel in the combustion chamber burns out, the fuel in the coal storage chamber will slide down to the combustion chamber by itself, and the combustion speed can be controlled by cooperating with the front and rear dampers. The heat generated by combustion heats the water.
