Mouth connects surge bunker, and the discharging opening of surge bunker bottom connects the charging aperture of metering machine for unloading coal, the discharging opening connection of metering machine for unloading coal
Pneumatic conveyer.Grind the coal dust completing 150 ~ 200 mesh from coal pulverizer station, through the thick and thin phase burner system of coal bunker bottom
System, delivers to pulverized coal warehouse silo roof, and in the case of inert gas installation protection, the pulverized coal warehouse that coal dust is discharged into stokehold is stored up
Deposit standby.By coal dust meausring apparatus, can be with the quality of coal dust in monitor in real time pulverized coal warehouse it is ensured that boiler burns for 48 hours
Amount.Control coal dust meausring apparatus, so that coal dust is entered into inside guiding storehouse, the metering feeder from guiding orlop end for the coal dust enters into
Surge bunker, metering feeder control enters into the coal dust amount within surge bunker it is ensured that the coal dust entering into surge bunker occurs without plate
Knot, closely knit situation, coal dust amount surge bunker within of being simultaneously into be enough to be filled into inside metering machine for unloading coal it is ensured that pneumatic transporting
Send the gas in device will not enter into inside surge bunker, control the amount of unloading coal of metering machine for unloading coal it is ensured that feed precision is missed simultaneously
Difference is less than ± 2%, under the drive of Pneumatic conveyer, the coal dust through metering is sent by way of dilute phase pneumatic conveying
Burnt to top combustion burner coal powder entrance, greatly improved efficiency of combustion.
Preferably, described pulverized coal warehouse top is provided with cleaner unit and Explosion-proof valve, in the mistake that pulverized coal warehouse is fed
Cheng Zhong, can discharge original air in pulverized coal warehouse, by pulverized coal warehouse roof scrubber, the coal dust in air-out be carried out
Collect, be allowed to flow back in Pulverized Coal Bin, will not spread everywhere, Explosion-proof valve ensures the safety and stability of whole device simultaneously.Coal dust stores up
Storehouse orlop is furnished with orlop fluidisation wind system and hopper wall vibrator it is ensured that the coal dust in pulverized coal warehouse will not be pressed because of pulverized coal warehouse storehouse
Hardened, closely knit situation occurs.
