Abstract

The utility model relates to a stable combustion gear energy conservation coal powder burner which comprises a burner body, a combustion chamber and an oil combustion chamber. The utility model is characterized in that the inner wall of the outlet of the combustion chamber is provided with a plurality of raised stable combustion gears. After the adoption of the structure, the primary air powder carries the coal powder to enter the combustion chamber, the high temperature oil fire sprayed by the combustion chamber and the oil combustion chamber is mixed to combust on fire, as the outlet of the combustion chamber is provided with a plurality of raised stable combustion gears, the combustion of the air powder is fiercer and more complete under the perturbation function of the stable combustion gears, so that the flame temperature and the combustion efficiency are improved and the purpose of energy conservation is achieved. By adopting the burner of the structure, the stable combustion of the boiler under low load is ensured; the stability and economical efficiency of the operation of the boiler are improved, and the oil cast combustion-supporting times of the boiler are greatly reduced.

Description

A kind of steady combustion pitch can coal burner
Technical field
The utility model belongs to a kind of coal burner, belongs to generating plant pulverized coal boiler starting ignition and low-load combustion-stabilizing burner particularly.
Background technology
Current coal is in short supply, the ature of coal that boiler is used is difficult to be guaranteed, when causing on the one hand in the running of power station high load capacity, ash erosion is serious, because general pulverized-coal fired boiler is lower than at 70% o'clock at load, burning can be unstable on the other hand, for keeping smooth combustion under the underload, it is combustion-supporting to throw oil again, has had a strong impact on the safety and economic operation of station boiler.Burner is the key that station boiler catches fire and surely uses, in order to save the fuel consume in heat power plant boiler startup and the steady combustion process, therefore develop a kind of coal burner that can increase substantially efficiency of combustion, in station boiler, use large tracts of land and promote, become a kind of active demand.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, efficiency of combustion is high, and steady combustion pitch can coal burner.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of steady combustion pitch energy coal burner, comprise burner body, combustion chamber, oil combustion chamber, it is characterized in that: described combustor exit place inwall is provided with the steady combustion tooth of several projections.
After adopting said structure: primary wind and powder carries coal dust and enters the combustion chamber, the high temperature oil flame mixing catching fire that in the combustion chamber, sprays with oil combustion chamber, because the combustor exit place is provided with the steady combustion tooth of several projections, under the perturbation action of steady combustion tooth, make the burning of wind powder more fierce, complete, improve flame temperature and efficiency of combustion, reached the purpose of energy savings.Adopt this structure burner can guarantee boiler smooth combustion under underload, improved the stability and the economy of boiler operatiopn, significantly reduced boiler and thrown oily combustion-supporting number of times.
In order to solve the problems of the technologies described above, the utility model also adopts following further technical scheme:
Described steady combustion tooth surely fires ring along circumferentially being spaced into profile of tooth.Adopt this structure can make flame combustion more stable.
Described steady combustion tooth is an inclined-plane towards the one side of combustor exit direction.After this has put this inclined-plane, reduced the resistance of air current flow in the burner, made the burning of wind powder rapider, thorough.
Description of drawings
Fig. 1 is vertical cut-away view of utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of steady combustion pitch energy coal burner, comprise burner body 1, be arranged on intrinsic combustion chamber 2, combustion chamber 2 can be provided with the one-level combustion chamber according to actual conditions, composite chambers such as secondary combustion chamber, combustion chamber 2 also is provided with an oil combustion chamber 3, the utility model improvements are: combustion chamber 2 exit inwalls are provided with the steady combustion tooth 4 of several projections, as shown in Figure 2,4 edges of steady combustion tooth described in this enforcement circumferentially are spaced into profile of tooth and surely fire ring, adopt this structure can make flame combustion more stable, the one side of steady combustion tooth 42 Way outs towards the combustion chamber is an inclined-plane 5,0 °＜the α of angle of described inclined-plane 5 and combustion chamber 2 inwalls＜90 °, this has put the purpose on this inclined-plane 5, be in order to have reduced the resistance of air current flow in the burner, to have made the burning of wind powder rapider, thoroughly.
In order to prolong the service life of burner, the utility model also is provided with an air film air compartment 6, air film air compartment 6 is provided with a ring-type air inlet 7, and the air film wind of introducing from secondary air box enters from ring-type air inlet 7, and air film wind plays the effect of cool burner wall and delivery of supplemental oxygen amount.
After adopting said structure: primary wind and powder carries coal dust and enters combustion chamber 2, the high temperature oil flame mixing catching fire that in combustion chamber 2, sprays with oil combustion chamber 3, because 2 exits, combustion chamber are provided with some steady combustion teeth 4, under the perturbation action of steady combustion tooth 4, make the burning of wind powder more fierce, complete, improve flame temperature and efficiency of combustion, reached the purpose of energy savings.Adopt this structure burner can guarantee boiler smooth combustion under underload, improved the stability and the economy of boiler operatiopn, throw oily combustion-supporting number of times having reduced boiler greatly.
This burner is used for generating plant pulverized coal boiler starting ignition and low-load combustion-stabilizing, both can be used as auxiliary burner, also can be used for main burner, and it is simple in structure, and low cost of manufacture is adapted at using in the station boiler and promoting.
