Dryer Drum plant Coal burner

Dryer Drum plant Coal burner

Scope: Our coal burner is mainly used in asphalt station, boiler, dry (such as brick kiln), metallurgy and other industries.

  Rotary Coal pulverized burner for asphalt plant Coal burner is mainly composed of pulverized coal machine, host of combustion machine(including combustion chamber, automatic back and forth motion system, automatic rotation system, the combustion air supply system) control system, ignition system, the crater and others.

  

  Dryer Drum plant Coal burner  components performance 

1.   Mini Coal pulverized burner for Drying Drum Various models and specifications for choose including MFJ20, MFJ40, MFJ80, MFJ120, MFJ150.
2. Mini Coal pulverized burner for Drying Drum The broken hammer is made by NM500 high wear-resisting material.
3.   Mini Coal pulverized burner for Drying Drum The coal screw is controlled by frequency converter for coal supply .
4. Mini Coal pulverized burner for Drying Drum First-class accessories (motor, reducer, bearing etc). User can specify a brand.
5.   Mini Coal pulverized burner for Drying Drum The shell manufactured by super thick high strength steel plate, which avoid the body vibration effectively.

Host of combustion Rotary Coal pulverized burner for asphalt plant :

It is composed of combustion chamber, automatic back and forth motion system, automatic rotation system, the combustion air supply system.

1. Mini Coal pulverized burner for Drying Drum Combustion chamber (independently rotating)                      
1)Our combustion chamber with larger diameter and longer length, the length of the pulverized coal preheating zone is increased, which make pulverized coal burning more fully and combusted more efficient.
2)Exclusive use of combustion chamber and rear cover separation design. (Patent number: 03216099.2)
3)Reasonable design ensures that the ignition device and air supply device with longer service life.


2.   Mini Coal pulverized burner for Drying Drum Auto-rotation and auto driving                                                        
1)Combustion chamber with motor, driven rotary in operation.
2)Exclusive use of furnace and air supply device separation design, effectively solve the problems such as firebrick collapse.

3.   Mini Coal pulverized burner for Drying Drum Burner Patented Design-easy for maintenance                   

The combustion chamber automatically rotation by the motor to prevent furnace slagging and improve the service life of refractory brick. The traditional burner need clean the slag 3-4 days, but our company's design greatly reduces the burners’ repair work. Our company use split design, so combustion chamber and air supply device moving forward and backward on the pully, which is easy for maintenance.

low NOx Discharge Coalpulverized burner
Mini Coal pulverized burner Firebrick
1)Customize the high quality firebrick, with temperature resistance, abrasion resistance and longer service life.
2)Standard size design, more convenient to use and replace accessories.

Mini Coal pulverized burner for Drying Drum Control system

1.PLC touch screen control system (SIEMENS Or Customized)
Our coal burner can be equipped with PLC touch screen control system. The whole control process visualization, the operation is simple and convenient. Meanwhile interface can use English, Russian, etc

2.Damper automatic adjustment-effectively reduce the coal consumption of burner

3.Automatic Temperature Control (optional)
1)According to the drying drum discharging temperature, real-time adjustment for coal supply.
2)All operations are on the control cabinet.
