Main Steps of Maintenance Method for Pulverized Coal Burner

1. Open the pulverized coal burner, check whether the coal hammer is damaged, and replace it if the damage is serious; Check whether the connecting anchor bolts of the fan impeller are loose and whether the blades are seriously damaged. If they are loose, they should be reinforced or replaced in time.

2. Check whether the anchor bolts outside the equipment are firm, check the scale in the combustion furnace, and repair the furnace charge.

3. Check whether the wear-resistant lining plates at the damaged parts are loosened from the anchor bolts that are fixed to the human body. The loosening should be firm. Replace the parts if the wear-resistant lining plates are seriously damaged.

4. The pulverized-coal burner shall check the lubrication of the rolling bearings in the front and rear rolling bearing chambers of the servo motor. If any scale is found in the vegetable oil, the lubricating oil shall be removed and replaced, and the replacement shall be determined according to the damage to the rolling bearing.

Pulverized coal burner application gunpowder manufacturing industry:

1. Quenching and tempering in steel rolling plant: easy to use, uniform heating, reducing labor, and saving 40% of coal.

2. Use of smelters: refining rare metals, such as lead smelting, aluminum smelting, antimony smelting, etc.

3. Roller drying equipment: the coal-saving rate of fly ash drying, water residue, pig manure, red rice wine, concentrate, organic fertilizer, anhydrite, coal slime, clean coal, and food is 40%

4. Heat transfer oil boiler: it can replace lump coal and be used for electric power engineering heating, saving 40% coal

5. Pharmaceutical enterprises adopt: replacing lump coal and gas producers to make up for the lack of heating surface.

6. Cement rotary kiln: the coal-saving rate of air-dried fly ash, water slag, pig dung, monascus wine, concentrate, organic fertilizer, anhydrite, slime, clean coal and food is 40%
