Description

Stoves with ring flue

technical field

The utility model belongs to a stove, in particular to a stove with an annular flue.

Background technique

Existing coal-fired stoves all have a furnace body, the bottom of the furnace body is provided with a furnace, and a combustion zone is provided directly above the furnace, on which a frying pan or a boiling pan is placed, and a plurality of outlets are arranged on the side wall of the combustion zone. The smoke outlet and the smoke outlet are connected with a flue, and the flue passes through the furnace body to directly introduce the smoke into the smoke and discharge it. The ignition port of this kind of stove is easy to be blocked, and the ignition is not smooth, and because the hot air in the combustion zone directly enters the flue, the temperature of the flue gas in the flue is relatively high, and this smoke exhaust structure causes these heat to be wasted in vain. The heating efficiency of the stove is reduced, resulting in waste of fuel.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and to provide a stove with an annular flue, which has a simple structure, sufficient combustion, high heating efficiency, and can reduce the weight of the stove.

In order to achieve the above object, the technical solution adopted by the utility model is: the stove with annular flue has a furnace body, the furnace body is provided with a furnace, and the upper part of the furnace has a combustion zone, a flare port and a flue, and is characterized in that: The ignition port is an annular ignition port, and the annular ignition port is arranged around the furnace body outside the combustion zone. The flue is an annular flue, and the annular flue communicates with the combustion area through the annular ignition port.

The annular firing port has a part located on the operating surface of the furnace body and a part away from the operating surface, and the horizontal position of the firing port located on the operating surface part of the furnace body is lower than the position of the firing port on the part facing away from the operating surface.

The annular flue communicates with an ash lowering passage that runs through the bottom of the furnace body, and an ash baffle is provided at the outlet of the ash lowering passage.

The beneficial effect of adopting the above technical solution: the stove with the annular flue has a fire opening and a flue, the fire opening is an annular fire opening, the ring fire opening is arranged around the furnace body outside the combustion zone, and the flue is an annular flue , the annular flue communicates with the combustion zone through the annular fire port. When the cooker is placed with a pot, the furnace body supports the pot, and the contact part between the furnace body and the pot forms a sealing surface, so that the flame can only be drawn out through the annular igniter after burning in the combustion zone. The surrounding of the pot is directly connected with the combustion area, so that the ignition is more uniform. The hot air introduced into the ignition port can directly heat the pot while circulating in the annular flue, and reuse the waste heat of the flue gas. The ring-shaped ignition port has a part located on the operating surface of the furnace body and a part away from the operating surface. The horizontal position of the ignition port located on the operating surface of the furnace body is lower than the position of the ignition port on the part away from the operating surface, so that the flame in the combustion area can be fully burned and the fire can be evenly emitted. partial fire phenomenon. The annular flue is connected with an ash lowering passage that runs through the bottom of the furnace body, and the outlet of the ash lowering passage is provided with an ash baffle, which is more convenient for cleaning the soot in the flue. Compared with the prior art, the utility model has the advantages of simple structure, sufficient combustion, high heating efficiency and light stove.

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

Description of drawings

Fig. 1 is the structural representation of the utility model.

FIG. 2 is a top view of FIG. 2 .

Fig. 3 is a sectional view along line A-A of Fig. 2 .

Detailed ways

Referring to Fig. 1, 2, the utility model has body of heater 1, and body of heater is provided with hearth 2, and hearth top has combustion zone 3, annular fire port 4, annular flue 5. The annular fire opening 4 is arranged around the furnace body outside the combustion zone 3 , and the annular flue 5 communicates with the combustion zone 3 through the annular fire opening 4 . The stove usually has an operating position and an operating position away from the operating position. The annular fire opening 4 has a part 6 on the operating surface of the furnace body and a part 7 away from the operating surface. As shown in FIG. The position of the ignition port that is lower than the part away from the operation surface, when the pot is placed on the stove, the distance 9 between the ignition port and the pot at the part away from the operation surface is smaller than the distance 8 between the ignition port and the pot below the operation surface of the furnace body The hot flue gas can be evenly drawn out from the ring-shaped ignition port. Connected with the annular flue 5, there is a lower ash channel 10 that runs through the bottom of the furnace body. The outlet of the lower ash channel is provided with an ash baffle 11. Open the ash baffle 11 when cleaning the soot in the flue, so that the soot can be discharged from the lower ash channel 10. .
