Description
Technical field
A kind of all-premixing burner is the utility model is related to, for gas instantaneous water heater and gas-heating water heater.Category
In technical field of combustion equipment.
Background technology
Conventional gas instantaneous water heater and gas-heating water heater uses atmospheric burning type, can produce substantial amounts of CO and nitrogen
Oxide（NOx）Deng waste gas.Therefore a kind of all-premixing burner is being researched and developed both at home and abroad, a kind of all-premixing burner has following
Feature：1. the reaction holdup time in flame high-temperature region is short so as to which reaction speed is fast；2. coefficient of excess air is small, burning velocity
It hurry up, the thermal efficiency is high, and the noxious gas emission such as nitrogen oxides and carbon monoxide is low.
A kind of flame hole arrangement of the fire row of existing all-premixing burner is horizontal, and the shape of hungry ghosts who spit fire is unanimous between the higher and lower levels,
There is tempering hidden danger, a kind of existing all-premixing burner is rich flame mouth, and flame profile is poor.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided all-premixing burner.
What the purpose of this utility model was realized in：
A kind of all-premixing burner, is characterized in：It includes multiple fire rows being arranged side by side, and the fire row includes dense flame
Cavity and light flame cavity, the light flame cavity are arranged on the both sides of dense flame cavity, and the bottom of light flame cavity is provided with
Air intlet, the middle part of light flame cavity with communicated in the middle part of dense flame cavity, be provided with light hungry ghosts who spit fire at the top of light flame cavity,
The bottom of the dense flame cavity is combi inlet port, and top is rich flame mouth, be provided with the hungry ghosts who spit fire be arranged side by side it is trapezoidal
Plate, adjacent two corrugated sheets form flame hole.
A kind of all-premixing burner of the utility model, there is gap between its two adjacent fire row.
A kind of all-premixing burner of the utility model, its fire row are made of stainless steel material.
Compared with prior art, the beneficial effects of the utility model are：
1. the utility model only with primary air, is a kind of all-premixing burner, a kind of burning of all-premixing burner
Reaction is fast, and auxiliary air plays a part of wall between adjacent two row of cooling.
2. there is the riser being arranged side by side in hungry ghosts who spit fire of the present utility model, adjacent two risers form flame holes, and traditional
The flame hole laterally arranged is compared, and stability is good and is not easy to be tempered.
It is copper because the thermal conductivity factor of stainless steel is relatively low 3. fire row of the present utility model is made of stainless steel material
1/20, therefore radiant heat caused by burner combustion does not interfere with the temperature of mixing chamber, actual measurement, the temperature of mixing chamber is on 40 DEG C of left sides
It is right.
4. there is gap so that surrounding air flows through mixing chamber surface between two adjacent fire rows of the utility model, work as spoke
When penetrating heat transfer to mixing chamber, in this gap in the presence of, heat caused by radiation is pulled away with surrounding air so that mixing
Room keeps low temperature.
5. rich flame mouth of the present utility model coordinates with light hungry ghosts who spit fire, the flame at light hungry ghosts who spit fire holds the flame at rich flame mouth 7, makes
It is good to obtain flame profile, high combustion efficiency.

Fig. 1 is a kind of schematic diagram of all-premixing burner of the utility model.
Fig. 2 is the top view of single fire row.
Fig. 3 is Fig. 2 left view.
Fig. 4 is the top schematic diagram of single fire row.
Fig. 5 is air-flow patterns of the present utility model.
In figure：
Combi inlet port 1,
Air intlet 2,
Light flame cavity 3,
Dense flame cavity 4,
Fire row 5,
Light hungry ghosts who spit fire 6,
Rich flame mouth 7.
Embodiment
Referring to Fig. 1-4, a kind of all-premixing burner is the utility model is related to, it includes multiple fire rows 5 being arranged side by side, institute
Stating fire row 5 includes dense flame cavity 4 and light flame cavity 3, and the light flame cavity 3 is arranged on the both sides of dense flame cavity 4, light
The bottom of flame cavity 3 is provided with air intlet 2, and the middle part of light flame cavity 3 communicates with the middle part of dense flame cavity 4, light fire
The top of flame cavity 3 is provided with light hungry ghosts who spit fire 6, and the bottom of the dense flame cavity 4 is combi inlet port 1, and top is rich flame mouth 7.
The riser being arranged side by side is provided with the hungry ghosts who spit fire 5, adjacent two risers form flame hole.
There is gap, such a structure is advantageous to gas and flowed up, and not only causes burner between two adjacent fire rows 5
High combustion efficiency, and can effectively prevent from being tempered.
The fire row 5 is made of stainless steel material, is the 1/20 of copper, therefore because the thermal conductivity factor of stainless steel is relatively low
Radiant heat caused by burner combustion does not interfere with the temperature of mixing chamber 3.1.
Operation principle：
Referring to Fig. 5, a kind of all-premixing burner of the utility model, air mixture enters from combi inlet port 1, and air is from sky
Gas import 2 enters, and an air mixture part is burnt through overrich flame cavity and at rich flame mouth 7, and another part enters light flame
Cavity mixes with air, and 6 burning at light hungry ghosts who spit fire；Such a structure, burn rate of the combustion gas at rich flame mouth 7 is fast, in light flame
Burn rate at mouth 6 is slow, and the flame at light hungry ghosts who spit fire 6 holds the flame of rich flame mouth 7 so that flame profile is good, high combustion efficiency.
