Coal Water Slurry Fuel Burner

Description of Coal Water Slurry Fuel Burner


Coal Water Slurry Fuel Burner belongs to turbulent burner. Turbulent burner adopts rotary jet design, have a larger spray divergence angle, which make the burner have a short gunshot and make the Coal-water slurry can be fired in a short furnace. There are recirculation zone inside and outside of the rotary jet, which will absorb high temperature flue gas and make sure the promptly fire of coal water slurry. The coal water slurry fuel is sprayed by central nozzle. Second compressed air become rotary airflow after through the axial adjustable hydro cyclones , forms a recirculation zone after getting out of nozzle and take the high temperature of the burner to the near nozzle, heat and ignite the coal-water slurry fuel. The first compressed air flow from the center hydro cyclones and combines with the second compressed air. This guarantees the burn process complete.

The coal-water has been widely used on 1t/h-20t/h boiler.

Advantage Feature of Romiter Coal Water Slurry Fuel Burner


1. Advanced swirling structure designed structure: Coal-water slurry flame don’t touch with the boiler wall, avoid slag-bonding
2. High quality spare parts : imported France SUNTEC brand oil ignition pump, imported PARKER brand light oil solenoid valve, Spain brand pneumatic actuators, and imported flame detection part. All these high quality part make sure the stable operation of the burner.
3. Wide load adjustment range: Adopt advanced coal-water slurry swirling burner design endow the burner wide load adjustment range from 40%-100%.
4. Long life span nozzle : multistage impact type coal water slurry burner use compressed air as atomization medium, compressed air get into the nozzle in an equal and opposite direction, so cancelled out. Without any wear to the nozzle.
5. High quality atomization and full combustion : the nozzle adopt Multi-stage collision type structure and the atomizer medium is compressed air, these make sure the atomization quality and full combustion of coal-water slurry
6. Automatic control design

  • Automatic purge furnace before ignition to eliminate the combustible gas in the furnace, prevent detonation
  • Automatic ignition, flame detection, interlocks protection device
  • Automatic advance and retreat function of coal-water gun, ignition gun, oil gun

7. Burning load is automatic variable frequency regulation with the load change of the boiler.

8. Safe operation design: Flame failure protection , automatic flame out and shut down burner during emergency and power cut ; Interlock protection with boiler operation equipment, such as breakdown situation of overpressure, overheat, low water, high water level , etc.

9. Easy to maintain: Coal-water spray gun automatic on-line cleaning: when the coal-water spray gun stop to spray coal-water gun, the compressed air and water automatic blow and wash the Coal-water spray gun, no need to take out of the Spray gun.
