Batubara Direct Burner

Main composing:

1. Coal Crusher
2. Cold Bin
3. Conveyor
4. Filler Supplying Device
5. Coal pulverizer,
6. Coal pipeline
7. Fuel ignition system,
8. Hearth bracket,
9. Coal fired chamber

Main function: Offer the needed hot source to the cold aggregates. The advantages: the cost is very low, the maintaining is convenient.
The operating method: Put the diesel tube into the rear of hearth, turn on the diesel pump and add the diesel oil, now ignite the diesel with the manual ignition pole, preheating about 1 minute later, start the coal pulverizer and add the coal, after the flame in being steady (about 3-5 minutes), shut off the diesel oil pump, now just only heat up the cold aggregates in the dry roller with the burning coal.
The characteristics of this four-passage spiral-flow coal burner: The shade is separate: burning stably, difficult to flameout, wide use; Compound spiral-flow: Burning stressed and fully; Air receiver powder: Dregs-proof and protect the bricks; Adjustable flame: Can regulate the length and thickness of the flame and reach the needed flame shape. This kind of burner aims at solving the five big problems of high-efficient, stable burning, low pollution, dregs proof and erosion, and can overcome such the limitations as the unstable burning, the few suitable coal kinds, serious dregs, heavy pollution, easy to be damaged for the brick and so on.

Benefit of using 2 in 1 Batubara Direct Burner (Coal and Diesel Oil)
1. It can substitute the oil with the coal, can save the fuel expense of mixer, reduce the operating cost greatly.
2. The special structure and rational layout of the hearth make the coal can burn fully and steadily and without any storing dregs.
3. Coal Fired Chamber can be rotated regularly to drop deposit dregs. It is not necessary to stop burner just to clean up deposit of dregs.
4. For the mutual function of the one-time spiral-flow wind and the adjustable direct-flow wind, not only can burn high-efficiently and stably but also can be suitable for the various coals’ combustion.
5. It is convenient to regulate online: According to the characteristic of various coals and the dry roller, can adjust the length, thickness and strong or weak of the flame at random, the adjustable range is large.
6. Can improve the service life of the brick greatly because of the burning type of air receiver coal ;
7. Easy to switch from coal burner to diesel oil burner without changing the apparatus.

The requirements of burning:
• The heat-generating quantity is bigger than 5000 cal / g
• The volatile component is bigger than 20%
• The whole moisture is less than 5%
