Abstract
The utility model discloses a controllable vortex flame diffusion cone, which comprises a hollow cone round table, wherein the conical surface of the hollow cone round table is welded with arc-shaped fins which are evenly distributed on the hollow cone round table along the circumference direction; the big-end side of the hollow cone round table is provided with a cylinder with an equal diameter with the bottom of the round table; the bottom center of the cylinder is provided with an air inlet; and vortex wind nozzles which are evenly distributed along the circumstance direction are aslant arranged between the bottom of the hollow cavity of the cone round table and the side surface of the cylinder. According to the controllable vortex flame diffusion cone is adopted, when high-temperature flame ejected from an ignition oil torch is injected to the controllable vortex flame diffusion cone, radial diffusion is generated by a rotational flow slot formed between the two fins of the outer edge of a blunt body by flame until a one-time air pipe wall surface to form a rotary fire surface, the contact area between pulverized coal and flame is improved so as to improve the ignition efficiency; and the retention time of the pulverized coal in a burner is prolonged, the firing stability is improved, air flowing through the cone at a high speed has a good cooling action on the cone, and therefore the working safety of the cone is guaranteed.
Description
Technical field
The utility model relates to a kind of coal burner and strengthens igniter, especially relates to a kind of controlled whirlpool flame spread awl that is used for little oil burner.
Background technology
The tiny-oil ignition combustion combustion supporting technology is station boiler igniting, the combustion supporting technology that present China gives priority to.According to the difference of coal, its oil-saving effect generally can reach 60～98%.But it is in the application of low volatile coal, and effect is not ideal enough.In the tiny-oil ignition technology, on the mode about oily flame ignition coal dust, all be to adopt single-point, multiple spot basically; That is to say, adopt single oil gun or many oil guns to light a fire, such mode contact area of flame and coal dust on the whole is less; Therefore, ignition performance is not good.How improving the contact area of flame and coal dust to greatest extent, is the key that improves ignition performance.
Summary of the invention
The purpose of the utility model is to provide a kind of controlled whirlpool flame spread awl, can make the controlled whirlpool flame spread awl with very strong ignition performance of flame radial diffusion formula from the center, and it can significantly improve combustion stability, and has good fuel tolerance.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
The utility model comprises a conulite round platform; On the conulite round platform conical surface, be welded with by circumferencial direction and be distributed on the arcuation fin on the conulite round platform, the conulite round platform is big distolaterally to be had and cylinder that the round platform bottom is isometrical; At cylindrical bottom centre place; Have a fresh air inlet, from the bottom of cone round platform cavity to the cylinder side, the oblique eddy current wind snout that along the circumferential direction is uniformly distributed with that has.
The axis of described eddy current wind snout and the angle of cone axis are greater than the angle between round platform cycloid and cone axis.
The beneficial effect that the utlity model has is:
Controlled whirlpool flame spread awl is installed in airduct; And make the torch oil gun spout over against the cone top, when the thermal-flame of torch oil gun ejection is sprayed onto controlled whirlpool flame spread awl when lasting, flame will be along eddy flow groove generation radial diffusion to the time airduct wall place that forms between bluff body outer rim two fins; In the whole circumference direction; Carry out strong turbulent matter, heat exchange with the breeze airflow in the incoming flow, heat coal dust rapidly, and can to a certain degree prolong the time of staying of coal dust; Thereby realized the igniting of anchor ring formula, improved ignition effectiveness greatly; Though the size of controlled whirlpool flame spread awl is certain, can pass through to regulate getting into the inner air quantity of cone, the circular cone build air curtain size that cone is outwards sprayed changes; Objectively be equivalent to be provided with the bluff body of adjustable size, therefore, regulated the high temperature recirculation zone size that combustor exit forms; Like this; Just can be according to coal-fired volatile matter size, the air quantity in the adjustment central air hose reaches adaptation coal effect of combustion.In addition, the existence of controlled whirlpool flame spread awl has further prolonged the time of staying of coal dust in burner, improves combustion stability, and high velocity stream has good cooling effect through the air of cone to cone simultaneously, to guarantee the security of cone work.
Description of drawings
Fig. 1 is the structure cutaway view of the controlled whirlpool flame spread awl of the utility model.
Fig. 2 is the structure left view of the controlled whirlpool flame spread awl of the utility model.
Among the figure: 1, conulite round platform, 2, inner chamber, 3, the arcuation fin, 4, fresh air inlet, 5, the eddy current wind snout.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1, shown in Figure 2; The utility model comprises a conulite round platform 1, and on conulite round platform 1 conical surface, welding (or integral cast) has by circumferencial direction and is distributed on the arcuation fin 3 on the conulite round platform 1; Conulite round platform 1 is big distolaterally to be had and cylinder that the round platform bottom is isometrical; At cylindrical bottom centre place, have a fresh air inlet 4, fresh air inlet 4 is communicated with the inner chamber 2 of conulite round platform 1; From the bottom of conulite round platform 1 cavity to the cylinder side, the oblique eddy current wind snout 5 that along the circumferential direction is uniformly distributed with that has.
The angle of described eddy current wind snout 5 axis and cone axis is greater than the angle between round platform cycloid and cone axis.
Situation was following when the controlled whirlpool flame spread of the utility model was bored real work:
Controlled whirlpool flame spread awl is installed in airduct, and makes the torch oil gun spout, when the thermal-flame of torch oil gun ejection is sprayed onto 1 last time of conulite round platform of controlled whirlpool flame spread awl over against the cone top; Flame will produce radial diffusion to time airduct wall place along the eddy flow groove that forms between the bluff body outer rim arcuation fin 3; Form the fiery face of a rotation,, carry out strong turbulent matter, heat exchange with breeze airflow in the incoming flow in the whole circumference direction; Heat coal dust rapidly; And can to a certain degree prolong the time of staying of coal dust, thus realized the igniting of anchor ring formula, improved ignition effectiveness greatly; Though the size of controlled whirlpool flame spread awl is certain, can pass through to regulate the air quantity that gets into the inner inner chamber 2 of cone, cone is changed through the circular cone build air curtain size that eddy current wind snout 5 outwards sprays; Objectively be equivalent to be provided with the bluff body of adjustable size; Therefore regulated the high temperature recirculation zone size that combustor exit forms, like this, just can be according to coal-fired volatile matter size; Adjustment gets into the air quantity of fresh air inlet 4, reaches to adapt to different coal effect of combustion.In addition, the existence of controlled whirlpool flame spread awl has further prolonged the time of staying of coal dust in burner, improves combustion stability, and high velocity stream has good cooling effect through the air of cone to cone simultaneously, to guarantee the security of cone work.
