Muti-channel low NOx discharge burner

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

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.

  

Coal burner componentsperformance                             

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

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

1.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.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.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.

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.

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.

The device includes the following parts:
1 Electric firing gun: Using electronic automatic ignition, safe in operation and easy to use.
2 Electric drive pusher: It’s for control the firing gun’s automatic forward or backward. After completion of the ignition, firing gun can be out of the combustion chamber automatically by the electric putter, which effectively protect the firing gun and prolong its service life.

Coal burner oil tank

Specific requirements for coal quality
At present, the size of input granules of our pulverized coal machine is 25mm or less, have greatly improved and raised applicability compared to the previous 5mm or less; coal combustion value is more than 4500Kcal making full use of a lot of inferior coal with low combustion value; volatile demand 25% or greater, sulfur content is 2% or less( rotation combustion chamber prevent furnace slagging); Net moisture content of 10% or less (equipped with powerful pulverized coal blower); ash content of 15% or less (high-energy ignition device guarantee ignition success rate)

Coal smashing machine
(super specifications lump coal broken to below 25 mm)
1.The smashing machine using 10mm steel plate, the heavy-weight make it work more stable.
2.The material of broken blade is NM500 (Please see the table)

MFR coal burner is our new generation heating device on the base of absorbing all the advantages of other manufactures, this product has the following features:
1.Adopts new structure, change the traditional burner mechanism, exclusive use of rotary combustion burners to solve the traditional burn which is easy to slag-bonding, can not burn completely etc.
2.High flame temperature, energy saving and completely burning.
3.Adopts the exclusive ingredients of firebrick of high performance, prolong service life.
