Description
Technical field
The utility model relates to the combustion of industrial boiler systems that a kind of vortex burner matches circle of contact burnout degree, belong to work
Industry boiler combustion system technical field.
Background technique
China's coal-burned industrial boiler overall technology level is lower, with unit operation testing efficiency generally 70% or so,
Actual operating efficiency is then lower, while pollutant emission is difficult to meet increasingly strict environmental requirement.And fuel-firing gas-firing industry pot
Although the big multipotency of furnace efficiency reaches 85% or so, economically and unreasonable due to being limited by operating cost and region.
For Industrial Boiler since burner hearth is small, space is tight, to improve efficiency of combustion or because of difficult arrangement, often no or cancellation combustion
Burner device causes discharged nitrous oxides high, pollutes environment or increases flue gas removing cost.Some swirl flow combustion industrial furnaces arrangement
Have and liquidate or the direct current pipeline of single-sided arrangement does fire air nozzle, due to space limitation be difficult to cover section of burner hearth it is abundant with flue gas
Mixing, does not have the purpose of fractional combustion.
Utility model content
Problem to be solved in the utility model is: existing Industrial Boiler is not provided with burner to improve efficiency of combustion
Device causes the problem that discharged nitrous oxides are high.
To solve the above-mentioned problems, the utility model provides a kind of industry of the vortex burner with circle of contact burnout degree
Boiler combustion system, including burner hearth, burner hearth are equipped with furnace outlet pipeline, which is characterized in that the burner hearth is filled equipped with burner
Set, burner apparatus, furnace outlet pipeline be located at freeze profile at burnout degree stratification of wind center line two sides, burner
Device includes the precombustion chamber being connected to in burner hearth and at least one vortex burner on the outside of precombustion chamber；On the outside of burner hearth
At least one layer of fire air nozzle is disposed with along flue gas direction.
Preferably, the burner centre in the burner hearth is First air/coal dust channel, and First air/coal dust channel periphery is set
There is secondary air channel, precombustion chamber is located on the outside of the nozzle of burner.
Preferably, the outer lateral edge flue gas direction of the burner hearth is disposed with 1~2 layer of fire air nozzle, every layer of fire air nozzle
Quantity is four, and the mounting means of fire air nozzle uses the wall circle of contact.
Preferably, the fire air nozzle is equipped with the swing mechanism for swinging it in vertical direction, swing angle 10
~30 °.
Preferably, the burnout degree is located at the side wall of the left and right sides.
Preferably, the air quantity of the burnout degree accounts for the 15~35% of total blast volume.
Preferably, when the furnace outlet pipeline is located at burner hearth bottom, burner apparatus is set to roof of the furnace；Work as burner hearth
When outlet conduit is located at roof of the furnace, burner apparatus is set to the side of burner hearth.
The utility model is made up of a kind of complete the after-flame wind system that vortex burner collocation wall is cut garden arrangement
New Industrial Boiler pulverized coal combustion system.Every layer of burnout degree can be enhanced and be disturbed to inner flue gas of the stove using the arrangement form in garden of cutting
Dynamic and mixing, meanwhile, fire air nozzle can be swung up and down, and be mixed into opportunity by adjusting optimal air is found, to greatest extent
Achieve the purpose that improve after-flame and controls discharged nitrous oxides.
