The sectional combustion technology is characterized in that the wall-mounted furnace is switched to be combusted by partial fire discharging pieces when the bath heat demand is low through the flow dividing of the proportional valve and the sectional characteristics of the combustor, so that the minimum combustion heat load of the wall-mounted furnace is reduced. When the water inlet temperature is too high in summer, the turning part fire exhaust fins are turned to burn to avoid the too high water outlet temperature, and when the water inlet temperature is lower in winter and the required burning load is increased, the turning part fire exhaust fins are turned to burn to avoid the unhealthy bath water in winter. In the switching process of the sectional combustion, the combustion load needs to have a superposition part; when the loads are misaligned, the loads are not continuous, and the loads are called load gear-breaking.

As shown in fig. 1-3, the utility model is a novel burner and a wall-mounted stove thereof, which comprises a burner front support 1, a burner rear support 2, a plurality of burner fire row sheets 3 and a square tube assembly 4, wherein the burner fire row sheets are supported between the burner front support and the burner rear support, the square tube assembly is provided with a nozzle group I4-1 and a nozzle group II 4-2, the nozzle group I comprises a plurality of nozzles I arranged along the axial direction of the square tube assembly, the nozzle I corresponds to the burner fire row I, the nozzle group II comprises a plurality of nozzles II arranged along the axial direction of the square tube assembly, the nozzles II correspond to the burner fire row II, and the aperture of the nozzles II is larger than that of the nozzle I.

The square tube assembly is fixedly installed on the combustor front support, and the plurality of combustor fire exhaust fins are arranged in parallel and perpendicular to the combustor front support and the combustor rear support. The square tube assembly is horizontally arranged and is vertical to the fire exhaust fins of the burner. The square tube assembly is provided with a first air inlet pipeline 4-3 communicated with the first nozzle and a second air inlet pipeline 4-4 communicated with the second nozzle, and the number of fire exhaust pieces for burning part of fire exhaust can be adjusted in the operation process of the wall-mounted furnace by arranging gas valves on the first air inlet pipeline and the second air inlet pipeline. The square tube assembly is internally provided with a first cavity 4-5 corresponding to the first nozzle and a second cavity 4-6 corresponding to the second nozzle, a partition plate is arranged between the first cavity and the second cavity for separation, the first air inlet pipeline is communicated with the first cavity, and the second air inlet pipeline is communicated with the second cavity.
As shown in fig. 4 and 5, the combustion load corresponding to the burner fire row two N2 is set to Q2, and the combustion load corresponding to the burner full fire row N is set to Q. The combustion load settings for the respective states are shown in Table 1 below
In the process of staged combustion, the combustion load needs to have a superposition part, so that gear breaking is avoided; setting the load superposition section as A, namely: Q2H-QL = a > 0, and the larger a, the less likely a gear-out will occur.
Compared with the existing burner, the burner provided by the utility model has the advantages that the size of the nozzle corresponding to the fire row sheet N2 is kept unchanged, and the maximum load combustion Q2H of the fire row sheet of the same wall-hanging stove is kept unchanged. The nozzles corresponding to the burner fire row fins N1 are reduced, the minimum load QL is reduced when the same wall-mounted furnace is burnt in a full fire row mode, and the load superposition section A = Q2H-QL is increased.
Taking a common wall-mounted furnace with a heat input of 20kW as an example, a burner commonly used in the existing wall-mounted furnace includes 10 fire rows, N =10, and a nozzle diameter of 1.3 mm. The maximum combustion load of a single fire row is 20 ÷ 10=2kW, and the minimum combustion load of a single fire row is generally 0.8kW according to experience. According to the basic principle that the load in the process of the staged combustion switching needs to have overlapping parts, the existing combustors commonly adopt N1=5 and N2= 5.
The burner adopts large and small nozzles, the diameter of the nozzle corresponding to the burner fire row two N2 is also 1.3mm, and the diameter of the nozzle corresponding to the burner fire row one N1 is 1.2 mm. Other configurations remain consistent with existing burners.
The two burners are respectively tested on the same 20kW wall-hanging furnace product, other structures and parameters are kept consistent, and the test results are as follows.
Table 2 two burner load comparison when N2=5
It can be clearly seen that: during the switching process of the staged combustion, the existing combustor is heavily loaded: 10-8=2, burner coincidence load of the utility model: 10-7.41= 2.59; the combustor can increase the load superposition section.
The burner can reduce the number of fire row sheets for burning part of fire row.
Two 10-fired staged burners were reproduced, with N2=4 and N1= 6. The burner adopts large and small nozzles, the diameter of the nozzle corresponding to the burner fire row two N2 is also 1.3mm, and the diameter of the nozzle corresponding to the burner fire row one N1 is also 1.2 mm. The control burner used a 1.3mm nozzle. The two burners are respectively tested on the same 20kW wall-hanging furnace product, other structures and parameters are kept consistent, and the test results are as follows.
Table 3, two burner loads when N2= 4.
| Fire of combustion Number of sheets arranged | State of the art burners Minimum load of combustion | State of the art burners Maximum load of combustion | The burner of the utility model State combustion minimum load | The burner of the utility model Maximum load of state combustion |
| N2=4 | Q2L=3.2 | Q2H=8 | Q2L=3.2 | Q2H=8 |
| N=10 | QL=8 | QH=20 | QL=7.29 | QH=18.22 |
As is evident from table 3: during the switching process of the staged combustion, the load is reset against the existing burner: 8-8=0, and is easy to break gear and is not suitable for use; the utility model burner overlap the load: 8-7.29=0.71, this approach is feasible; the burner adopts large and small nozzles, the number of fire row pieces for burning part of fire rows can be reduced in the staged burning process, and the minimum load Q2L is changed from 4kW to 3.2 kW.
Compared with the prior art, the problem of reduction of the maximum load QH caused by the adoption of large and small nozzles in the combustor can be solved by adjusting the opening degree of the proportional valve, and explanation is not expanded here.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
