Problems solved by technology

[0003] However, limited by burner technology, there are still many problems in civil automatic stoves, which affect the market development of stoves
Mainly, the existing burners have the following deficiencies in use: insufficient combustion, poor slag removal ability, and can only burn biomass, semi-coke, anthracite and other fuels with an ash content not higher than 10%. When the ash content is higher than 10% of the fuel, the coke in the burner will be difficult to remove, and the combustion effect is very poor; the fuel adaptability is poor, and only biomass or coal with a volatile content of less than 10% can be used to burn at the same time. Biomass and coal are used; especially, for the burning of bituminous coal, which accounts for more than 70% of coal resources, there will be severe smoke, CO and NO x High, difficult slag removal, high amount of residual carbon in the bottom slag, poor combustion stability and many other problems

Embodiment 1

[0042] This embodiment provides a burner. Such as figure 1 As shown, the burner includes a casing and an air distribution plate 1 . The air distribution plate 1 is arranged obliquely upward in the housing, and divides the inner space of the housing to form an upper combustion chamber 100 and a lower ventilation chamber 200 . Specifically, the air distribution plate 1 includes an isolation section 12 and an upwardly convex curved section 13 which are sequentially connected from bottom to top, and a plurality of first ventilation holes are dispersedly arranged on the upwardly convex curved section 13 . Along the inclination direction of the air distribution plate 1 , the upper combustion chamber 100 has a low end and a high end. A fuel supply port 101 and an ash discharge port 102 are respectively provided at the lower end and the upper end of the upper combustion chamber 100 . Fuel can enter the upper combustion chamber 100 through the fuel supply port 101 for combustion, an...

Embodiment 2

[0064] This embodiment provides a burner and a stove. The structure of this burner is substantially the same as that of the burner provided in Embodiment 1, the only difference is that the shape of the bottom cover plate 4 is different.

[0065] Specifically, as Figure 6 As shown, the bottom cover plate 4 can have multiple folded edges to adjust the structure of the lower ventilation chamber 200 and facilitate the installation of the burner in the stove. Further, the inspection opening 41 can also be arranged on the side of the bottom cover 4 , so that the operator can enter and exit the inspection opening 41 conveniently. However, it should be noted that when adjusting the shape of the bottom cover plate 4 , the ventilation area of ​​any position in the lower ventilation chamber 200 should not be smaller than the ventilation area of ​​the primary air inlet 201 .

Embodiment 3

[0067]This embodiment provides a burner and a stove. The structure of this burner is substantially the same as that of the burner provided in Embodiment 1, the only difference is that a cooling wind jacket 6 is provided along the circumferential direction of the upper combustion chamber 100 .

[0068] Specifically, such as Figure 7 As shown, the cooling air jacket 6 is provided with a cooling air inlet 61 and a cooling air outlet 62 , and the cooling air outlet 62 communicates with the ash discharge port 102 of the upper combustion chamber 100 . After the cooling air is introduced into the cooling air jacket 6, the upper combustion chamber 100 can be cooled, and the temperature of the combustion zone C can be lowered, so that the efficiency of sulfur fixation can be effectively improved when burning briquettes containing a sulfur fixation agent. At the same time, since the cooling air outlet 62 communicates with the ash discharge port 102 of the upper combustion chamber 100,...

Abstract

The invention provides a combustor and a stove, and relates to the technical field of civil combustion equipment. The combustor comprises a shell and an air distribution plate arranged in the shell obliquely and upwards. The air distribution plate divides inner space into an upper combustion chamber and a lower ventilation chamber. The air distribution plate comprises an isolation segment and an upper convex curve segment which are sequentially connected from bottom to top, and multiple first ventilation holes are dispersedly arranged on the upper convex curve segment. A fuel feed opening andan ash discharging opening are formed in the low end and the high end of the upper combustion chamber in the oblique direction of the air distribution plate. A primary air inlet is arranged at one endof the lower ventilation chamber. By means of the combustor, sufficient combustion of fuel can be achieved, discharging of CO, NOx and other pollutant gas is effectively reduced, the residua carbon quantity in ash is reduced, smokeless combustion is achieved, ash clearing is smooth, and the combustion requirement of multiple kinds of fuel can be met.

Description

technical field [0001] The invention relates to the technical field of civil combustion equipment, in particular to a burner and a stove. Background technique [0002] In recent years, as a comprehensive clean heating solution other than "coal to gas" and "coal to electricity", combustion equipment such as automated stoves has developed rapidly in the field of civil clean heating. [0003] However, due to the limitations of burner technology, there are still many problems in civil automatic stoves, which affect the market development of stoves. Mainly, the existing burners have the following deficiencies in use: insufficient combustion, poor slag removal ability, and can only burn biomass, semi-coke, anthracite and other fuels with an ash content not higher than 10%. When the ash content is higher than 10% of the fuel, the coke in the burner will be difficult to remove, and the combustion effect is very poor; the fuel adaptability is poor, and only biomass or coal with a vo...
