In novel burner, the outlet of the outlet end wrapping inner layer casing of middle casing may be implemented to contain ammonia in inner layer sleeve
Fuel of the fuel of gas by the minimum ignition energy in middle casing less than ammonia wraps up.Due to ammonia minimum ignition energy compared with
Height, gaseous ammonia can light ammonia after being mixed into fuel of the minimum ignition energy less than ammonia, to solve ammonia fuel smallest point
The fiery higher defect of energy.Wrap up the outlet of the inner layer sleeve in the outlet end of the middle casing.Minimum ignition energy is less than
The fuel of ammonia prior to containing ammonia fuel spray burner, minimum ignition energy less than ammonia fuel ignition point compared with
It is low, it is readily ignited.Minimum ignition energy is burnt in air less than the fuel of ammonia first generates amount of heat, refires and contains
There is fuel combination of the fuel of ammonia with minimum ignition energy less than the fuel mix of ammonia, ammonia is made fully to burn.Existing skill
Four-way structure (cross) and three-port structure (T fonts) mixing arrangement of art cannot achieve the technique effect lighted in advance.
Further, the outlet of the middle casing is wrapped up in the outlet end of the outer layer sleeve.The outlet of outer layer sleeve with
There are certain distances for the outlet of middle casing.Inner layer sleeve outlet fuel and middle casing outlet fuel this in access into
After row is sufficiently mixed, then is exported and sprayed by outer layer sleeve.
Further, the radial center overlapping of axles of the inner layer sleeve, middle casing and outer layer sleeve.In each layer casing
Air-flow is more unobstructed, and easier to process and manufacture.
Further, which can be less than the fuel of ammonia：Contain hydrogen, natural gas, water-gas, stone
The fuel of oil gas, kerosene, gasoline, diesel oil, methanol, ethyl alcohol, ether or dimethyl ether.These minimum ignition energies are less than the combustion of ammonia
Material plays the role of assisting the ignited fuel containing ammonia.
Further, the utility model also provides a kind of burner, including combustion chamber, igniter and burner, the combustion
Burning nozzle is above-mentioned ammonia fuel combustion nozzle, and the fuel containing ammonia that the burner sprays is less than ammonia with minimum ignition energy
Fuel lighted through igniter, and burn in the combustion chamber.There is N in the flue gas that burning generates2, CO2, H2O is to environment friend
Aerobic body, does not generate toxic and harmful gas.
Compared with the background art, it has the following advantages that the technical program：
The utility model ammonia fuel combustion nozzle can solve the technical issues of ammonia fuel is difficult to light.Wherein, it is covered using middle level
The exit design of the inner layer sleeve is wrapped up in the outlet end of pipe, can effectively light the fuel containing ammonia.Also, outer layer sleeve
The outlet that the middle casing is wrapped up in outlet end makes fuel be more fully mixed.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structure chart of ammonia fuel combustion nozzle of embodiment one；
Fig. 2 is the structure chart of another ammonia fuel combustion nozzle of embodiment one；
Fig. 3 is the structure chart of the burner of embodiment two.
Specific implementation mode
Embodiment one：
Ammonia fuel combustion nozzle as shown in Figure 1, including inner layer sleeve 3, middle casing 2 and outer layer sleeve 1, inner layer sleeve 3
Entrance be passed through ammonia, the entrance of middle casing 2 is passed through minimum ignition energy, and less than the fuel of ammonia, (the present embodiment is：Hydrogen
Gas), the entrance of outer layer sleeve 1 is passed through air.In the burner of the utility model, the outlet 21 of middle casing is wrapped up in described
The outlet 31 of layer casing, the ammonia that may be implemented in inner layer sleeve 3 are wrapped up by the hydrogen in middle casing 2.Hydrogen is prior to containing
The fuel of ammonia sprays burner, and the minimum ignition energy of hydrogen is only/0.02MJ, is readily ignited.Hydrogen is in air first
Middle burning generates amount of heat, refires the fuel combination that ammonia or ammonia are constituted with hydrogen, ammonia is made fully to burn.Ammonia
After ignited can sustained combustion, can stop supply middle casing 2 in hydrogen.The four-way structure (cross) of the prior art
It cannot achieve the technique effect for lighting the fuel containing ammonia in advance with three-port structure (T fonts) mixing arrangement.
Fig. 2 show the ammonia fuel combustion nozzle of another structure, and the outlet 11 of the outer layer sleeve 1 of the ammonia fuel combustion nozzle is wrapped
Wrap up in the outlet 21 of the middle casing 2.There are certain distances with the outlet 21 of middle casing for the outlet 11 of outer layer sleeve.Internal layer set
The hydrogen of ammonia and the middle casing outlet 21 of pipe outlet 31 is after this is sufficiently mixed in access, then after being mixed with air
Burning is sprayed by outer layer sleeve outlet 11.There is N in the flue gas that mixed fuel firing generates2, CO2, H2O does not generate poisonous and harmful gas
Body.
Embodiment two：
Ammonia has that ignition quality is poor as fuel, and the autoignition temperature and minimum ignition energy of ammonia are high, wherein most
Small ignition energy is up to 680MJ.Fuel etc. of the minimum ignition energy less than ammonia is often added in order to make ammonia more fully burn
Minimum ignition energy as combustion adjuvant, such as gasoline, ether, methanol is 0.2MJ.Therefore the present embodiment is devised such as Fig. 3
Burner be used for by ammonia, minimum ignition energy be less than ammonia full combustion of fuel.The ammonia fuel combustion nozzle is to be based on ammonia
And minimum ignition energy less than the fuel of ammonia characteristic and utility model, it is therefore intended that allow minimum ignition energy to be less than ammonia
The fuel of gas burns first generates heat, to ensure fully lighting for ammonia.Ammonia fuel combustion nozzle is by inner layer sleeve 3, middle casing
2, outer layer sleeve 1 forms.Ammonia in the inner layer sleeve 3 in bosom by being passed through, and methanol is passed through by middle casing 2, and air is by outer layer
Casing 1 is passed through.The end of ammonia fuel combustion nozzle is arranged inside combustion chamber 5.It is provided on the fuel emission direction of burner
Igniter 4, the methanol in middle casing 2 are ignited device 4 after spraying and light first, and subsequent ammonia reaches at the combustion range of methanol
In the case where being wrapped up in methanol, burning generates high-temperature flue gas.Wherein inner layer sleeve 1, middle casing 2, the caliber of outer layer sleeve 3 are relatively large
It is small to make corresponding adjustment during fabrication according to the different capacity or different use demands of boiler.Due to internal layer set
Pipe is in direct contact with corrosive gas ammonia, therefore use stainless steel is as material, or according to the heterogeneity of fuel by this practicality
It is novel to be changed to other suitable materials.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation of the utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
