Abstract

The utility model discloses a domestic coal stove hearth, comprising an upper stove hearth body (1) and a lower stove hearth body (2). An upper edge of the upper stove hearth body (1) is provided with three rims (3) for supporting a heat receiver, and the rims (3) are evenly distributed along the circumference. Shoulders (4) for placing grates are arranged on an inner wall of the lower stove hearth body (2). The upper and the lower stove hearths (1), (2) form a bird-caging stove chamber (5). As a bird-caging stove chamber structure is adopted, fuel can be fully combusted in the bird-caging stove chamber. Flame temperature at a stove mouth is higher that of an old coal stove with a cylindrical stove chamber. Thereby, the heat efficiency of the coal stove, and the utility model has good energy-saving effect.

Description

A kind of civil combustion chamber

The utility model belongs to domestic stove, is specifically related to a kind of civil combustion chamber that can burn charcoal and coal.

As the saying goes, " bread is the staff of life ", diet is human conditions on which persons or things depend for existence, since the mankind found fire, fire had just become the main means of people's processed foods.Along with the progress in epoch, development of science and technology, and the continuous development and use of the new energy, people have had progressive significantly and raising on fiery kind and method.Yet coal and coke remain one of main energy, particularly also are in the status that can not be substituted as domestic fuel.For this energy of better utilization, people have particularly carried out exploring untiringly, studying and improve to its combustibility aspect to coal stove, have formed to differ from one another the civil stove and accessory that series is numerous.But what people generally used in the daily life still is the old-fashioned coal furnace of cylindrical burner hearth.Though this coal furnace is simple in structure, it is difficult to there is igniting, incomplete combustion, and ignition temperature is low, and drawback the such as promptly thermal efficiency is low has caused the serious waste of the energy thus.As seen, in today of human energy growing tension, transform, eliminate the inevitable requirement that this old-fashioned coal furnace has become energy-conservation and even era development.

It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, and igniting is quick, and burning is complete, thermal efficiency height, effectively the civil combustion chamber of energy savings.

The utility model is achieved in that this fire coal combustion chamber includes upper and lower furnace core body, and there is the flange of the support heated body that is uniformly distributed along the circumference last furnace core body upper edge, and in the following furnace core body convex shoulder of shelving fire grate is arranged, bird-caging in the burner hearth that upper and lower furnace core body constitutes.

Because the utility model has adopted the chamber structure of bird-caging, make igniting easier, fuel can be burnt in burner hearth fully, and the flame temperature at fire door place is greatly improved than old-fashioned coal furnace, thereby improved the thermal efficiency of coal furnace effectively, reached the purpose of energy savings.

Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.

Fig. 1 is the vertical view of the utility model one embodiment:

Fig. 2 be the AA of Fig. 1 to cutaway view:

As shown in the figure, civil combustion chamber of the present utility model, comprise furnace core body 1 and following furnace core body 2, there are three flanges 3 that are used to support heated body that are uniformly distributed along the circumference on the edge on the last furnace core body 1, the convex shoulder 4 of shelving fire grate is arranged on the inwall of following furnace core body 2, upper and lower furnace core body 1,2 constitutes bird-caging burner hearth 5, and the radius ratio of upper and lower fire door 6,7 and burner hearth 5 is 1: 1.2.

The utility model has adopted the chamber structure of bird-caging, the inherent characteristic of this structure, burner hearth increases from the exhausting ability when making burning, air/fuel ratio when promptly having improved burning in the burner hearth, improved combustibility, not only igniting is more quick, and the old-fashioned coal furnace of the more cylindrical burner hearth of flame temperature greatly improves, can reach more than 1000 ℃, thereby reach the purpose of energy savings.Through Preliminary Determination, use the combustion chamber 20--30% capable of saving fuel of the utility model.

The sidewall of the bird-caging burner hearth of the combustion chamber of the utility model can be different shapes such as circular arc, straight shape, preferably circular arc.The radius ratio of upper and lower fire door 6,7 and burner hearth 5 can be 1: 1.1-1: 1.3.

The upper and lower furnace core body the 1, the 2nd of the combustion chamber of the utility model forms with fire clay is integral sintered, therefore, has advantages such as fire-resistant, long service life.This combustion chamber also can be processed into integral body.

The combustion chamber of the utility model is simple in structure, shapes conveniently, and is with low cost, the production efficiency height.

The combustion chamber of the utility model is as a kind of core component of general civil stove, applicable to pluralities of fuel, as the solid fuels such as coal of coke, different shape.

The utility model can also be for using under the multiple occasion, and as kitcheners such as family, restaurant, dining rooms, the main heat supply of small-sized household coal heating equipment is with stove etc.
