Description

A kind of coal furnace and its boiler

technical field

The utility model relates to coal-fired heating equipment, in particular to a coal furnace and its boiler.

Background technique

As a kind of heating equipment, coal stove is widely used in people's daily life. Coal stoves used in current daily life generally include a furnace body, an air duct and a furnace, wherein the furnace is arranged in the furnace body. When in use, place the cooking utensils to be heated on the top of the furnace body and ignite coal for heating. Since the hearth of the existing coal furnace is set in the furnace body, most of the heat generated when the coal is burned is dissipated on the inner wall of the furnace body , and a small part of the heat is transferred to the top through the furnace to heat the cooker. Wherein, due to the irregular shape of the cooker, when the cooker is placed on the top of the furnace body, there will be a large gap between the cooker and the top of the furnace body. When the coal stove works, a part of heat will also be lost from the gap. Therefore, the defects in the structure of the coal stove itself and the irregular shape of some cooking utensils directly lead to poor heating effect of the coal stove, low heat utilization rate, and great waste of coal resources.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

Example 1.

As shown in Fig. 1 to Fig. 2, a kind of coal furnace of the present utility model comprises furnace body 1 and furnace hearth 2, and described furnace body 1 is provided with first air channel 11, and described first air channel 11 and furnace hearth 2 In the same way, the furnace 2 extends out of the top of the furnace body 1 .

When working, ignite the coal placed in the furnace 2, because the furnace 2 extends out of the top of the furnace body 1, the heat generated when the coal burns will be fully released, and timely ventilated to the first air duct 11, which can make the furnace 2 Coal is burned more fully and resource utilization is higher.

The furnace body 1 is provided with an ash chamber 12, and the furnace 2, the ash chamber 12, and the first air duct 11 are communicated in sequence. Wherein, the furnace body 1 is provided with an ash chamber 12, and during the coal combustion process, charcoal slag or ashes will fall, and the charcoal slag or ash will uniformly fall into the ash chamber 12, which is convenient for cleaning.

A grate 13 is provided at the junction of the furnace 2 and the ash chamber 12 . The grate 13 is designed as a grid, which can not only support the coal placed in the furnace 2, but also play a role in ventilation.

The first air duct 11 includes an extension portion 111 extending out of the furnace body 1 , and the extension portion 111 is provided with a damper cover 112 . When the coal is not fully burned or a brighter flame is needed, open the damper cover 112 and ventilate, so that the coal can fully contact with the air, the coal will be burned more fully, and the flame will be brighter; when a bright flame is not needed, close the damper cover 112, It is enough to reduce the contact of coal with air.

The furnace body 1 is also provided with a handle 14 , and the handle 14 is movably connected with the furnace body 1 . Handle 14 is movably connected with body of heater 1, can carry coal stove sideways.

As shown in Figures 3 to 4, the utility model provides a boiler, the bottom of the boiler is provided with a boiler bottom cavity 3 matching the furnace 2, and the boiler is also provided with a second air duct 31. The second air channel 31 communicates with the bottom cavity 3 of the pot. The boiler is used in conjunction with the coal stove, wherein the pot bottom chamber 3 cooperates with the furnace 2 extending from the top of the coal stove, so that the contact area between the boiler and the furnace 2 is larger, and when the coal in the furnace 2 burns, the The heat will be more fully dissipated to the boiler wall, the heat exchange area between the furnace 2 and the boiler is increased, and the utilization rate of heat generated by coal combustion is fully improved. The boiler is provided with a second air duct 31, wherein the second air duct 31 communicates with the pot bottom chamber 3, and when the coal in the furnace 2 burns, the second air duct 31 can lead to more air to the furnace 2, so that the coal The combustion is more complete and the utilization rate of coal resources is improved.

The height of the pot bottom cavity 3 is greater than the height of the furnace 2 extending from the top of the furnace body 1 . The height of the pot bottom cavity 3 is greater than the height of the furnace 2 extending out of the top of the furnace body 1. It can be said that when the boiler is set on the coal stove, a gap is formed due to the height difference between the pot bottom cavity 3 and the furnace 2, allowing the furnace 2 to be placed The coal can be in contact with the outside air to provide the oxygen needed for combustion.

The top of the stove pot is provided with a pot cover 4 . The pot cover 4 has the effect of preventing the heat loss in the furnace pot.

Example 2.

As shown in Figures 1 to 4, the upper part of the furnace 2 is provided with a convection port, which can make the furnace 2 communicate with the outside world. When the height of the bottom of the pot cavity 3 was less than the height that the hearth 2 extended out of the top of the body of heater, the boiler was placed on the coal stove, because the height of the bottom of the pot cavity 3 was less than the height of the top of the body of heater 1 extended by the hearth 2, the bottom of the pot cavity 3 seal the furnace mouth, but the upper part of the furnace 2 is provided with a convection port, so that the coal placed in the furnace 2 can be in contact with the outside air, so as to realize the heating work of the coal furnace.

The rest of this embodiment is the same as the first embodiment, and will not be repeated here.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
