Abstract
The utility model relates to a kind of low nitrogen vacuum boilers of combustion gas, including the igniter being arranged on burner and its puff prot, igniter includes the air jet pipe for collecting fiery cylinder and its interior coaxial arrangement, collect upstream-end opening, the downstream closing of fiery cylinder, the relatively turnable friction pulley for being equipped with outer peripheral surface and using pig iron material on air jet pipe, friction pulley external friction is combined with the steel stone of the annular on the inner wall for being fixed on and collecting fiery cylinder, and the upstream of friction pulley is provided with the rotational flow generator communicated with air jet pipe.The characteristics of can lighting a fire after being rubbed using steel stone, eliminate electronic igniting and the setting of ever-burning flame, on the one hand insecure phenomenon of frequently lighting a fire caused by electronic igniting is avoided, ever-burning flame bring maloperation problem is on the other hand avoided, to improve equipment reliability of operation and safety.
Description
Technical field
The utility model belongs to field of boilers more particularly to a kind of low nitrogen vacuum boiler of combustion gas.
Background technique
Currently, the low nitrogen vacuum boiler of combustion gas includes super low NO, gas distribution pipe, burner hearth, heat convection pipe, fin
Condenser pipe, primary fluid water, internal and external screw pipe group, the super low NO is connected with a gas distribution pipe, described right
Stream heat exchanger tube is arranged in the combustion zone of vacuum hot water boiler burner hearth with one group, and the heat convection pipe rear area is one group of fin
Condenser pipe, the heat convection pipe and finned condensation pipe are connected to primary fluid water phase, and the internal and external screw pipe group is located at vacuum
Above hot-water boiler.One flame is divided into several flammules by a gas distribution pipe, since flammule heat dissipation area is big,
Temperature is lower, declines thermal response NO, in addition, flame is small, shortens residence time of the gases such as oxygen, nitrogen in flame, to " heat
Reaction NO " and fuel NO has apparent inhibiting effect.
But need to be additionally provided with a female fire-fighting mouth at puff prot in burner to avoid frequently lighting a fire, work as burning
When device works, female fire-fighting mouth is first opened, then lights the combustion gas that female fire-fighting mouth sprays with igniter, forms a female fire, then open
Puff prot is opened, female fire lights the combustion gas of puff prot ejection, and burner works normally, only need to be puff prot when burner pause
It closes, at this point, female fire burns away, when burner is again started up, puff prot need to only be opened, without as ordinary burner
Equally frequently igniting；Only when long-time does not have to burner, just extinguish female fire by closing female fire-fighting mouth.It is such to set
It sets, plays ever-burning flame function.The problem of being easy to appear maloperation adversely affects the service life of entire boiler.
Utility model content
The purpose of this utility model is to provide a kind of low nitrogen of combustion gas for avoiding ever-burning flame igniting bring adverse effect is true
Empty boiler, its technical solution is as follows:
The low nitrogen vacuum boiler of combustion gas, including the igniter being arranged on burner and its puff prot, igniter includes collecting fiery cylinder
And its air jet pipe of interior coaxial arrangement, collect upstream-end opening, the downstream closing of fiery cylinder, relatively turnable assembly on air jet pipe
There is outer peripheral surface to use the friction pulley of pig iron material, friction pulley external friction is combined with the fire of the annular on the inner wall for being fixed on and collecting fiery cylinder
Sickle stone, the upstream of friction pulley are provided with the rotational flow generator communicated with air jet pipe.
The overflow hole being provided between rotational flow generator and friction pulley on the tube wall of air jet pipe.
Rotational flow generator has twice, and twice rotational flow generator is equipped at intervals with four friction pulleys, and the eddy flow in downstream
Generator is also equipped with the overflow hole close to upstream position.
Overflow hole is distributed on air jet pipe in dot matrix.
The beneficial effects of the utility model are as follows:
The characteristics of can lighting a fire after being rubbed using steel stone, is eliminated electronic igniting and the setting of ever-burning flame, on the one hand kept away
Exempt from insecure phenomenon of frequently lighting a fire caused by electronic igniting, on the other hand avoids ever-burning flame bring maloperation problem, from
And improve equipment reliability of operation and safety.
Detailed description of the invention
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the embodiments of the present invention, for this
For the those of ordinary skill of field, without any creative labor, it can also be obtained according to these attached drawings other
Attached drawing；
Fig. 1 is the igniter structure schematic diagram of boiler.
Specific embodiment
In order to keep the technical purpose, technical scheme and beneficial effects of the utility model clearer, with reference to the accompanying drawing and
Specific embodiment is further illustrated the technical solution of the utility model.
Referring to Fig. 1, the igniter structure schematic diagram of the low nitrogen vacuum boiler of combustion gas of the utility model is shown.The igniter
On the puff prot of burner, by way of mechanical ignition, guarantee the reliability and safety of igniting, specific structure is such as
Under:
The low nitrogen vacuum boiler of combustion gas includes the igniter being arranged on burner and its puff prot, and igniter includes collecting fiery cylinder 1
And its air jet pipe 2 of interior coaxial arrangement, the upstream-end opening of the fiery cylinder 1 of collection, downstream are closed, relatively turnable on air jet pipe 2
It is equipped with the friction pulley 3 that outer peripheral surface uses pig iron material, 3 external friction of friction pulley is combined on the inner wall for being fixed on and collecting fiery cylinder 1
The steel stone 4 of annular, the upstream of friction pulley 3 is provided with the rotational flow generator 5 communicated with air jet pipe 2.Rotational flow generator 5 and friction
The overflow hole 6 on the tube wall of air jet pipe 2 is provided between wheel 3.Rotational flow generator 5 has a twice, twice rotational flow generator 5 it
Four friction pulleys 3 are equipped at intervals with, and are also equipped with the overflow hole 6 close to upstream position in the rotational flow generator in downstream 5.
Overflow hole 6 is distributed on air jet pipe 2 in dot matrix.
When in use, combustion gas enters in the fiery cylinder 1 of collection through air jet pipe 2 in the puff prot of burner, through eddy flow in collecting fiery cylinder 1
The spiral of generator 5 plays drainage, swirling eddy is generated in fiery cylinder 1 collecting, swirling eddy drives friction pulley 3 to rotate, friction pulley 3
Rotation caused by friction phenomenon light combustion gas, to jet out flames from the downstream opening for collecting fiery cylinder 1, realize multi-point spark and spray
The effect of fire.
It should be noted last that: the technical solution of the utility model that the above embodiments are only illustrative and not limiting is appointed
What to the utility model carry out equivalent replacement and do not depart from the spirit and scope of the utility model modification or part replace,
It should cover within the scope of the utility model claims protection.
