Product Details

PLC control and automatic ignition coal dust burner /pulverized coal burner

Pulverized coal burner for industry feature:

1. Sufficient burning, flame powerful, strong, not hurting kiln coating, repairable , low expense of after-sales service.

2. Adjustable boiler temperature and flame length

3. Advanced structure, high performance

4. The main parts are made of high temperature resistance ceramic element, it is more stable and reliable when working, the system investment is small.

Application:

Pulverized coal burner for industry is applicable to a variety of annealing furnace, metal furnace, boiler, asphalt plant,hardening furnace, precision casting shell burning furnace, melting furnace, forging furnace and other furnace kiln.

Main technical parameter of Pulverized coal burner for industry:

Type	Power (kw)	Coal consumption (kg/h)	Asphalt Plant Capacity (t/h)	Mixture Temperature Control (°C)
DB500	35	450	25-40	130-180
DB1000	47.5	900	60-80
DB 1500	73	1200	80-100
DB2000	93.5	1600	120-160
DB3000	155	2400	200-240
DB4000	185	3200	260-320

Characteristic of Pulverized coal burner for industry:

1. Based on the mechanism of forming NOx (forming NOx mechanism and fuel NOx mechanism) during the course of burning of fuel to form NOx, to control the NOx content in fume.

2. Muti-channel low NOx discharge burner can make the NOx consistence in fume greatly decrease, 40-60% lower than normal, by applying feedback result to indicate that the NOx content in fume at end of kiln normally is 350~400 ppm, about 50% lower than ordinary value 800 ppm which have reached the advance level in international.

3. the shape and length of flame for Muti-channel low NOx discharge burner can meet the requirement for calcining technics and temperature distribution in rotary kiln, and the shape and length of flame can be adjusted.

4. the temperature of flame can be controlled, that is the top temperature can be controlled, therefore to prevent the material over-burning, to make the kiln avoid forming ring block.

5. muti-phase burning and mixing burning can be adapted, also can be used sole burning in single-phase fuel.

Requirements of the Coal:

Item	Parameter	Remark
Feeding size	≤25mm	Compared to the previous request of ≤5mm, it’s great improved and applicable.
Coal combustion value	≥4500Kcal	Many low combustion value of inferior coal has been fully used.
Volatile	≥25%
Sulphur content	≤2%	Rotary combustion chamber solve the slag problem.
Moisture content	≤10%	Powerful Pulverized coal blower
Ash content	≤15%	High energy ignition device ensure ignition success rate
