Background technology
With attention of the public to air environmental pollution, the pollution of coal-fired Industrial Boiler, arcola faces severeer
Pressure is administered or closes down, therefore cleaning coal utilization technology is more and more paid attention to.And simultaneously, find cleaning alternative energy source
It is a kind of solution route, such as the regenerative resource such as biomass, or natural gas, alcohol-based fuel etc..
Alcohol-based fuel is generally low boiling fuel, is easier complete decomposition combustion, is a kind of replacement energy more cleaned
Source.But the ignition burning device of current comparative maturity is fuel oil or gas burner, is not fully adapted to alcohol-based fuel.It is various to be
The burner that alcohol-based fuel burns and designed has the combustor based on liquid fuel design（As CN105674261A,
CN106196045A etc.）, also there is gasification combustor（Such as CN105509047A, CN103196139A）.Current alcohol-based fuel gas
Change burner and the problems such as gasification result is poor, gasification installation is easily stifled be present, and liquid burner often opposed configuration complexity,
Effect is not sufficiently stable.In addition, the mode of igniting gasification is often difficult to effectively control excess air factor to ensure low nitrogen in burner
Burning.
Liquid fuel after vaporization can be used as fuel gas, and its burner, burner can consider according to fuel gas.Cause
This, the mixing and the setting of cloth wind in burner are extremely important, especially when realizing low nitrogen burning.And the at this time design of shower nozzle
It is even more important.
Utility model content
The utility model provides a kind of nozzle for gaseous combustion blender, effectively improves uniformity of fuel spray
And its premix uniformity with First air.
The utility model is achieved by the following technical solution：
A kind of nozzle for fuel gas blender, including straight section pipe, shower nozzle section and connection straight section pipe and shower nozzle section
Linkage section；The straight section pipe diameter d0More than shower nozzle section maximum cross-section diameter d1；The linkage section is arc line shaped linkage section；Institute
State shower nozzle section and be provided with multiple spouts, multiple spouts are respectively along the radial and axial arrangement of shower nozzle section；The shower nozzle section end is
Blind end, shower nozzle section endcapped are disposed with spout on face；Multiple spout central lines are in flaring centered on shower nozzle section center line
Shape is arranged.
In above-mentioned technical proposal, the shower nozzle section is isometrical uniformly straight section or terminad arc line shaped flaring shape；The shower nozzle
The diameter d of section maximum cross-section1Less than or equal to straight section pipe diameter d01/2 ~ 1/3, i.e. d1≤(1/2~1/3)d0。
The preferred scheme of above-mentioned technical proposal is that the nozzle exit product is Ain, the shower nozzle section maximum secting area is A1,
The sectional area summation of the multiple spout is less than or equal to 1/3 ~ 1/5 times of shower nozzle section maximum secting area A1, i.e. n nozzle exit product
Summation nAin≤(1/3~1/5)Ai。
In above-mentioned technical proposal, the gaseous fuel pressure P in straight section pipe0Relative value is 0.01 ~ 0.05 atmospheric pressure, that is, is compared
High 0.01 ~ 0.05 atmospheric pressure of pipe external environment pressure.
Compared with prior art, the beneficial effects of the utility model are：Straight section adds tapered nozzle arrangements, especially tapered
Divergent nozzle structure, increasing fuel emitted dose prevent spout to block, enhance fuel and gas while improving jet velocity
Mixing.

Embodiment
Concrete structure of the present utility model, operation method and implementation are carried out with embodiment below in conjunction with the accompanying drawings detailed
Discuss.
The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and
Establish.Accompanying drawing is different, then corresponding position relationship is also possible to change therewith, therefore can not be interpreted as with this to protecting model
The restriction enclosed.
A kind of nozzle for fuel gas blender described in the utility model, including straight section pipe 1, shower nozzle section 2 and company
Meet straight section pipe 1 and the linkage section 4 of shower nozzle section 2, straight section pipe diameter d0More than shower nozzle section maximum cross-section diameter d1, linkage section 4 is camber line
Shape linkage section, make connection of the straight section pipe 1 with shower nozzle section 2 tapered for arc line shaped, air and fuel energy is mixed rapidly.
