What are the reasons for the damage to the furnace of the biomass pellet hot blast stove?

　　Reasons for the damage to the furnace of the biomass pellet hot blast stove:

　　1. The air volume of the combustion furnace is too small, and there is a dead angle on the surface of the furnace. It is necessary to increase the wind speed of the combustion furnace, and the wind speed above 0.5M/S is normal.

　　2. Improper adjustment of the combustion furnace during the test machine. When the feeding speed of the pellets reaches a certain value, the draft is large, the oven heats up quickly, and the heat loss is large, but the temperature of the furnace surface will decrease; otherwise, the furnace surface will rise. high, causing heat accumulation.

　　3. When the furnace is designed, the surface heat dissipation area is small, which is easy to be damaged by heat accumulation.

　　4. The furnace wall is too thick, causing heat accumulation damage.

　　5. The nickel content of the raw materials of the furnace is too low, and materials with a nickel content of more than 20% should be used.

　　6. Small selection, fast feeding, and overload operation for a long time, thus causing damage to the boiler.

　　7. When the machine is shut down, the machine does not follow the operating procedures to shut down, and does not perform the delayed shutdown operation, which will cause the furnace temperature to overheat and damage the boiler.

　　8. The height of the furnace is not enough, so the top burns.

　　9. The primary and secondary air supply air volume in the furnace is not enough, causing the top to burn.

　　10. Carbon deposits in the furnace for a long time, and carbonization damage caused by not cleaning.
