Description
Technical field
The coal powder distribation device used in a kind of power plant is the utility model is related to, more particularly to a kind of novel adjustable one
Divide two pulverized coal distributors.
Background technology
The boiler of power plant overwhelming majority in China is by the way of coal dust firing, and the performance driving economy of pulverized-coal fired boiler is very big
The flow operating mode of wind powder in wind powder system is depended in degree.The situation of wind powder flow uniformity difference often destroys normal combustion
Burning process, it is unfavorable to coal powder ignition, after-flame, efficiency of combustion is influenceed, causes velocity field in stove, combustible substance concentration field and temperature field
The generation of the dangerous phenomenons such as exception, ash erosion, tube wall hot-spot；Simultaneously it is also possible to that furnace flame center can be caused inclined
Tiltedly, unstable combustion, local coking, booster, boiler thermal output decline, even result in boiler flameout and blow out and induce production accident.
At present in the field control and monitoring of pulverized-coal fired boiler, by the static pressure in First air air channel come judge air quantity, by
Powder machine rotating speed (bin system) and feeder coal-supplying amount (pressurized direct pulverizing coal system) carry out indirect control and judge coal
Powder concentration, while burnt by the adjustment to throttle opening come tissue.Found in actual motion, although boiler is using progress cold conditions
Aerodynamic field test method carries out leveling to primary air system, and cool power field experiment can only ensure that boiler combustion system same layer is each
Primary air piping and can not ensure to flow through in primary air inlet in actual motion to the resistance balance in the cold state of burner outlet
Resistance balance during coal dust-air mixture, coal powder density differs in each primary air piping when resulting in boiler actual motion for this
Causing, although some boilers are equipped with non-dimmable grid-type coal-ash distributor, but after boiler longtime running, due to non-dimmable grid
Formula distributor can not carry out free adjustment to the coal dust of each tube cell of pulverized coal preparation system, cause the coal dust of each pipeline enclosure to match and occur partially
Difference, this just causes very big difficulty to burning regulation, it is impossible to ensures the Effec-tive Function of boiler, or even induces accident.
At this stage, traditional pulverized coal distributor main Types have diffused pulverized coal distributor, radial mode coal powder distribation and lattice
Grid-type pulverized coal distributor, but can not effectively solve large sized unit coal powder distribation caused by pulverized coal channel resistance is unbalanced
The problem of deviation.
