Description

A coal-fired energy-saving furnace

technical field

The utility model relates to a stove, in particular to a coal-fired energy-saving stove. the

Background technique

At present, most households in rural areas still use old-fashioned stoves for boiling water, cooking, and heating. This kind of stove can only burn lump coal, and the heat conversion rate is low, which wastes energy. the

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a coal-fired energy-saving furnace with a large heating and heating area, energy saving and environmental protection. the

The utility model is achieved in the following manner. A coal-fired energy-saving furnace is mainly composed of a furnace body, a furnace core, a hood, a water inlet, a water outlet, an air intake pipe, and a smoke exhaust port. The lower part of the furnace body is the ash box, which has an ash outlet, and the ash box communicates with the furnace core through the furnace bridge. The annular cavity formed between the furnace body and the furnace core is the lower water circle, and the lower water circle has a water inlet; there is a hood above the furnace body, and the middle water circle is placed between the upper water circle and the hood. There is a gap between the upper hydrosphere, the cover head and the cover plate, the lower hydrosphere and the upper hydrosphere are connected by a ten-day connecting pipe, and the upper hydrosphere and the middle hydrosphere are connected through an inner connecting pipe. The upper water circle has a water outlet, and the hood head is in the middle water circle. There are holes in the circumferential direction of the hood head. There is a cover plate above the hood head. The cover plate is ring-shaped, and the small cover can be placed on the hood head through the inner diameter of the ring-shaped cover plate. Above, the small cover is a round cover with four protrusions at the bottom. When the small cover is covered, there is a gap between the small cover and the middle water circle, and the furnace core and the hood head are respectively connected to each other by an air inlet pipe and a blower. the

Compared with the prior art, the utility model has three major technical characteristics:

1. There are three water circles around and above the furnace core, which can effectively improve the heat conversion efficiency;

2. The middle water circle is placed overhead between the upper water circle and the hood. There is a gap between the middle water circle and the upper water circle, the hood, and the cover, and there is also a gap between the small cover and the hood. When the small cover is covered When the flame is blocked by the small cover and the cover plate, it will move along the gap below the middle hydrosphere and between the middle hydrosphere and the upper hydrosphere, increasing the heating area of the upper hydrosphere and the middle hydrosphere;

3. The hood and the furnace core are respectively connected with the air inlet pipe and the blower, which is conducive to full combustion. the

The utility model has the beneficial effects of fast heating speed and high thermal efficiency. the

Detailed ways

Below in conjunction with accompanying drawing, the specific technical scheme of the utility model is further described. the

As shown in Figure 1, a coal-fired energy-saving furnace consists of a furnace body (1), a furnace core (2), a furnace bridge (3), a lower water circle (4), an upper water circle (5), a middle water circle ( 6), hood (7) cover plate (8), water inlet (9), water outlet (10), air inlet pipe (11), outer connecting pipe (12), inner connecting pipe (13) and small cover (14 ) and smoke outlet (15) composition. The body of heater (1) is a cylindrical shell welded by a steel plate, and a cavity in the bottom of the shell is an ash box, and the ash box has an ash outlet and an ash outlet cover. A furnace bridge (3) is arranged between the ash box and the furnace core (2), and the furnace core (2) is a conical shell with a large upper part and a smaller lower part. ) The annular cavity formed between the outer wall and the inner wall of the body of heater (1) is the lower water circle (4), and the lower water circle (4) has a water inlet (9). The top of the furnace body (1) is an annular upper water circle (5), the upper water circle (5) is connected with the lower water circle (4) by an external connection pipe (12), and the upper water circle (5) has a water outlet for external heating. The upper water circle (5) has a smoke outlet (15)) to be connected with the flue. On the top of the furnace core (2) there are middle water circle (6) and hood (7), the middle water circle (6) is placed between the upper water circle (5) and the hood (7), through the inner connecting pipe ( 13) and the intake pipe (11) are overhead fixed, so there is a gap between the middle hydrosphere (6) and the upper hydrosphere (5) and the hood (7), the middle hydrosphere (6) and the upper hydrosphere (5) Internal connecting pipe (13) is arranged to communicate, and cover head (7) is cylindrical shape, and circumferential direction is distributed with holes, and cover head (7) has air inlet pipe (11) to be connected with blower. Cover plate (8) is an annular iron plate, and internal diameter is greater than the outer diameter of small cover (14), and small cover (14) is placed on the top of cover head (7) by the endoporus of cover plate (8), and small cover (14 ) has four protrusions, and when covering the small cover, there is a gap between the small cover (14) and the cover head (7). the

Compared with the prior art, the utility model can not only burn lump coal, but also burn crushed coal, and can save coal by 40-50%. the
