pulverized coal injection is used to grind and offer pulverized coal.It is made up of appending funnel,feeding structure.After the coal briquette is crushed and ground,it is sent to the burning furnace in powder shape.

1.Structure and principle of the Pulverized coal burner:

 The raw coal of no more than 20mm granularity is injected into the host combustion chamber through a metal hose nozzle by the pulverized coal injection machine and lighted by oil gun atomized diesel. At the same time, the air blower blow air to the combustion chamber through the annular rotary air flue on the host back cover. The air rotates forward against the inner wall andentrains high-temperature smoke flow and burns strongly with pulverized coal. The high-temperature flame flow is injected into the heating furnace by the burner.

2.Coal burner characteristics :

1)Using the exclusive revolving burning chamber to solve traditional burning problems, such as relict agglomeration and burning incompletely.

2)high flame temperature, so that burn fully and save energy.

3)Equipped with exclusive fire-brick, prolonging the service life.

4)Continuous work, don’t need to clear clinker everyday.

5)The low cost of fuel expense, just as 1/2 of oil cost

3.Requirements for the coal

1)igniting oil : 0# diesel oil

2)Requirements for the coal:

  Bituminous coal

(a)calorific power >25KJ     

(b) Volatile content≥25%

(c) Ash content 8~10%

(d)moisture: 3~4%

(e)Sulfur content ≤1%      

(f)Granularity ≤20mm

4.The Characteristics Of the Pulverized coal burner:

1)Use new type structure and rotary type exclusively.

2)High-temperature and long-distance flame; energy saving, fully combusted and continuous producing.

3)Use high-performance firebrick of exclusive ingredients, which can lengthen the service time.

5.Application of the Pulverized coal burner:

 It applies to industries which need heat source, such as drying, annealing, tempering, casting, steel rolling, smelting, chemical engineering, cement, boiler etc.

Technical parameters of the Pulverized coal burner:

Packaging:  Standard export packing (Waterproof rust), Nude cargo and spare parts in wooden

cases (special fumigation-free wooden material).

Shipping:  Int'l Shipping, Road / railway / air / ocean transportation, or multimodal transport
