Description
Technical field
The utility model is related to a kind of burner of boiler test platform, more particularly to for the burning of supercharged steam generator testing stand
Device.
Background technology
Supercharged steam generator refers to replace air blower that the boiler of combustion air is conveyed to boiler furnace using compressor.In its burner hearth
Heat transfer process of the combustion process and flue gas of fuel in furnace heating surface is in superatmospheric power（Commonly reach 0.2MPa-
0.5MPa）Under carry out.Supercharging can promote fuel combustion and furnace heat transfer process, therefore can effectively improve boiler efficiency, drop
The discharge of low stain thing, while mitigating both weight, reduces boiler size.In addition, installing hot water or steam after supercharged steam generator
Waste heat boiler, can more improve its economy.
But then, supercharged steam generator has larger difference with normal-pressure boiler, due to supercharged steam generator furnace volume heat release rate ratio
Conventional boiler is much higher, thereby results in many key technologies such as burning, heat transfer, flowing, material, Performance Match and conventional boiler not
Together；The structure of device, system and regulation and control are all more complicated simultaneously, therefore supercharged steam generator is applied to only pursue performance mostly in the past
Military project naval vessel, the research to supercharged steam generator is also limited to Turbo-charged Marine Boiler.
With the raising of production technology, the originally high supercharged steam generator part of production cost has started to be applied to industry neck
Domain.By taking critical piece-turbocharger therein as an example, turbocharger also had been widely used for automobile etc. in recent years
Industry, have accumulated the design of a large amount of turbocharger, production, using experience, and production cost declines to a great extent, and can meet work
The reliability requirement that industry is used.Therefore, the condition of exploitation land supercharged steam generator is ripe day by day.
Burner is the critical piece of boiler.Due to pressure increase to the catching fire of fuel, burn, the process such as after-flame has shadow
Ring, so as to influence the structure of burner, it is therefore desirable to which the critical piece to atmospheric burner carries out parameter improvement, with suitable for increasing
Pressure combustion system.
The content of the invention
To solve the deficiencies in the prior art, there is provided a kind of oil burner of matched with pressurization boiler test platform, this burning
Device matched with pressurization boiler, remained to when air feed pressure is low keep burner catch fire, surely combustion characteristic it is good, when air feed pressure is high burn effect
Rate is high, at the same it is rational in infrastructure, beneficial to maintenance.
To achieve the above object, the utility model uses following technical scheme：
A kind of oil burner for supercharged steam generator testing stand, including located at fire inspection interface, the point at combustor inlet end
Fiery interface, tubing interface and duct collar, are fixed with nozzle casing in burner, and nozzle is provided with nozzle casing, spray
Mouth is communicated with tubing interface；Air register is fixed with the port of export side of nozzle；Air register water conservancy diversion exhaust vent is cut along nozzle casing
To uniform, and the opening size ecto-entad of each water conservancy diversion exhaust vent reduces；Burner inner liner is arranged on the port of export of burner, flame
Cylinder end inwardly reduces.
Fuel nozzle is arranged in the nozzle casing of front opening in burner body, and sleeve pipe is used to dismantle and install nozzle
With.The increase of combustion air pressure can improve atomizing effect, flame column body Relatively centralized, the utility model during in view of pressurized combustion
Using solid type nozzle.So-called solid nozzle refers to that the fuel oil for spraying converges into filled circles in the plane of certain distance, relatively
For solid nozzle, also nozzle, semisolid nozzle etc..
Because pressurized combustion can improve combustion intensity, it is therefore desirable to accordingly increase combustion air volume；But then, supercharging
Combustion air can have a negative impact to flame.Air register uses usually used tangential prismatic blade, in the utility model burner
The air register of use is reduced the water conservancy diversion exhaust vent between tangential prismatic blade from outside to inner side, and increases outside
Circulation area, suitably to reduce inner second air, and increased total secondary air flow.
Burner inner liner is arranged on burner body front end, and its shape is in cylindrical type, but near outlet side, that is, connects the one of burner hearth
Side is slightly shunk, and its Main Function is that good pressure stability region is formed at burner outlet, is carried when reducing pressurized combustion
Influence after back pressure high to catching fire, surely firing.
Duct collar is connected with air feed system, and air feed system is the passage that combustion air is flowed through, and air feed uses forced air supply, wind
Source is roots blower and turbocharger.Pressure limit is in 0-30kPa（Gauge pressure）Between.
Tubing interface is connected with oil supply system, the fuel system part such as including fuel tank, oil pump, magnetic valve, and fuel oil uses No. 0
Light diesel fuel.
Fire inspection interface is used to connect flame detector, and igniting interface is used to connect igniter.During burner ignition, flame
Detector closes igniter after detecting the signal that stabilization is burnt.Burner such as runs into that flame is unstable, it is different to put out a fire when running
Reason condition, flame detector can and alarm, it is ensured that burner trouble free service.
Detachable knot is both designed as in order to test convenient needs, burner inner liner, fuel nozzle, air register of this burner etc.
Structure, i.e., be threadedly coupled with burner body by nut.
The utility model is the primary combustion equipment for supercharged steam generator testing stand, is increased to fuel spray according to furnace pressure
The influence that change, evaporation, combustion zone come, nozzle, air register and burner inner liner to burner are improved.The utility model structure
Succinctly, influence of the boost conditions to burner is taken into full account, the operation of supercharged steam generator testing stand can be effectively applicable to, be supercharging pot
The research and development of stove provide safeguard.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model
Fig. 2 is the structural representation of the utility model air register flow-guiding mouth.
Marked in figure：1 burner body, 21 fire inspection interfaces, 22 fuel oil interfaces, 23 igniting interfaces, 3 duct collars, 4 sprays
Mouth, 41 nozzle casings, 5 air registers, 51 air register water conservancy diversion exhaust vents, the 61 burner inner liner ports of export narrow place, 62 burner inner liners.
Specific embodiment
Referring to the drawings, a kind of oil burner for supercharged steam generator testing stand, including located at the fire at combustor inlet end
Inspection interface 21, igniting interface 22, tubing interface 23 and duct collar 3, are fixed with nozzle casing 41, in nozzle in burner
Nozzle 4 is provided with sleeve pipe, nozzle is communicated with tubing interface；Air register 5 is fixed with the port of export side of nozzle；Air register water conservancy diversion
Exhaust vent 51 is tangentially uniform along nozzle casing, and the opening size ecto-entad of each water conservancy diversion exhaust vent reduces；Burner inner liner 61 is pacified
Mounted in the port of export of burner, burner inner liner end 62 inwardly reduces.
Nozzle spray angle reduction more appropriate than normal pressure combustion scheme in this example, is advisable with no more than 60 degree, because supercharging combustion
Burning mode can make flame column body Relatively centralized, therefore nozzle spray angle can not be too big, is otherwise unfavorable for after-flame；While jet angle
Flame degree of filling can be also influenceed if degree is too small.Nozzle spray angle is determined by the subtended angle of nozzle.
