The working principle of the invention and process are as follows: First air carries coal dust and is entered by First air coal dust streamtube, first
Be located at First air coal dust streamtube inside Pulverized Coal Concentration ring meet, Pulverized Coal Concentration ring be it is hollow pyramidal and up big and down small,
During hitting Pulverized Coal Concentration ring, air-flow swerves First air breeze airflow, since pulverized coal particle density is larger, big partial size
Pulverized coal particle is during hitting Pulverized Coal Concentration ring, by the inertia effect, it is easier to be repelled into First air coal dust streamtube
It at the heart and is enriched with, forms the higher thick coal culm air-flow of coal powder density, at the same time, (predominantly partial size is smaller for a small amount of pulverized coal particle
Pulverized coal particle), the effect of inertia being subject to due to itself is weaker, follows the mobility of air-flow preferable, makes a small amount of coal dust in this part
It is still flowed along air current flow direction, to be formed about around thick coal culm air-flow close to First air breeze airflow inside pipe wall
The lower thin powdered coal air-flow of coal powder density.The thick coal culm air-flow formed at First air breeze airflow tube hub is directly by thick coal culm
Airflow channel sprays, in the thin powdered coal air-flow that First air breeze airflow inside pipe wall is formed about along in First air coal dust streamtube
Wall flowing, initially enters conical ring channel, by the guiding role in conical ring channel, thin powdered coal air-flow finally by conical ring channel into
Enter the inside of thin powdered coal airflow channel, and the guiding role by axial swirl blades, the high speed ejection in a manner of rotational flow,
To form low-pressure area at the center of high speed rotation air-flow, the formation of the low-pressure area can be such that thin powdered coal air-flow returns after ejection
Low-pressure area is flowed to, to form the high temperature recirculation zone at burner outlet.At the same time, Secondary Air is entered by secondary air channel,
First by the guiding role of tangential vane, biggish tangential rotational velocity component is generated, and by secondary air channel exit high speed
Eddy flow sprays, and similarly, further promotes the formation of high temperature recirculation zone at burner outlet.
In structure of the invention, First air breeze airflow makes coal powder density in thick coal culm air-flow increase to concentration by concentration
Preceding 2 times or more, ignition heat needed for advantageously reducing different types of coal coal dust firing make this part coal dust advanced combustion form main fire
Flame heats and lights thin powdered coal air-flow.High-speed rotating thin powdered coal air-flow and Secondary Air facilitate at burner outlet to be formed
The coal dust in thin powdered coal air-flow and thick coal culm air-flow is lighted in high temperature gases recirculating area.So as in more coals and varying duty item
Promote coal powder ignition, steady combustion and after-flame under part.
Meanwhile First air breeze airflow, after concentration, coal powder density greatly improves in thick coal culm air-flow, realizes effective
Coal powder light-dark fractional combustion advantageously forms the strong reducing zone in pulverized coal flame, makes the N element of release largely to NH3Or N2
Conversion inhibits NO x It generates.Also, oxygen amount needed for coal dust firing initial stage is successively supplied by thin powdered coal air-flow, secondary air separating two-stage
It gives, so that coal dust is remained at the lower burning of also Primordial Qi point, to reduce the NO in process of coal combustion x It generates.In thick coal culm gas
Internal stripper loop is set between circulation road and thin powdered coal airflow channel and is arranged between thin powdered coal airflow channel and secondary air channel outer
Part spacer ring makes to keep certain distance to spray burner between thick coal culm air-flow, thin powdered coal air-flow and Secondary Air three, to postpone
Thick coal culm air-flow, thin powdered coal air-flow and the triangular mixing of Secondary Air further extend coal dust and stop under also Primordial Qi point
The time is stayed, is conducive to inhibit NO x It generates, reduces NOx emission.
First air breeze airflow is divided into positioned inside by the Pulverized Coal Concentration ring being arranged in First air coal dust streamtube
Thick coal culm air-flow and thin powdered coal air-flow positioned at outside further pass through cloth while realizing coal powder light-dark fractional combustion
The axial swirl blades being placed in thin powdered coal airflow channel spray thin powdered coal air-flow high speed rotation at burner outlet.It should
Kind combustion method can make thin powdered coal air-flow while there is tissue pulverized coal bias combustion and building burner outlet high temperature to return
The effect for flowing area avoids in general type vortex burner and realizes burner outlet by building multi-layer rotational flow Secondary Air
High temperature recirculation zone, simplify burner structure, burner dimensions accordingly reduce, and keep burner structure more compact, are conducive to
The flexible arrangement and reduction burner processing cost of burner in actual application.
The present invention, which passes through, postpones mixing between tissue pulverized coal bias combustion, bias pulverized coal air-flow and Secondary Air, realize that coal dust is steady
Fixed burning promotes coal dust after-flame and reduces NO x The purpose of generation, with coal adaptability is strong, load regulation range is wide, low NO x It is raw
At and compact-sized advantage.
Connection of the present invention includes but is not limited to the modes such as be spirally connected, weld, and based on used by the prior art
Corresponding manner.
A specific embodiment of the invention above described embodiment only expresses is only used as the explanation to the present invention program
And explanation, it cannot be construed as a limitation to the scope of the present invention.It should be pointed out that for the common of this field
For technical staff, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to this
The protection scope of invention.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
