1. Local small pieces of slag in the gas generator were not processed in time, resulting in excessive local ash content.

Because the resistance of coal ash is smaller than that of coal ash, the air volume is larger in places where coal ash is high, resulting in strong gasification and higher and higher coal ash. In places where coal ash is low, the coal ash layer is relatively thin. Such a vicious cycle will cause serious furnace partiality. Half of the fire layer reaches the furnace head, and the other half of the reduction layer no longer exists. Therefore, furnace conditions must be checked frequently and slag must be dealt with promptly to avoid partial furnace accidents.

2. Another reason is due to the poor condition of the original furnace.

During ignition, due to the uneven distribution of slag in the furnace, or the slag containing larger slag, or the uneven burning of the entire furnace section after ignition, the eagerness to discharge the slag causes one end of the furnace to catch fire and the other end to catch fire, forming a partial furnace phenomenon.

3. Inhomogeneity of coal in the furnace

Because the position of the coal spreading cone is not adjusted properly and the furnace condition is not checked frequently, it is easy to cause more coal at the side and less coal at the side. Where there is a lot of coal, the resistance of the material layer is large, the air volume is reduced, the reaction is slowed down, and there is less ash. In places where there is less coal, the resistance of the material layer is small, the air volume is increased, the reaction is accelerated, and the ash is formed quickly. Over time, eccentric operation is likely to occur.

4. The non-uniformity of slag output causes partial furnace phenomenon

Because it's smallgas generatorOnly one large ash knife is installed, so the ash is crowded in front of the large ash knife and behind the ash knife. The ash and slag are relatively loose. Because of the inconsistent resistance of the material layer, an offset operation is formed. The position and length of the dust knife can be appropriately adjusted to achieve uniform dust removal.

5. The primary fan’s air supply is uneven, causing system bias

Because the grate is eccentric, and it is inevitable that the margins between layers are not consistent during the installation process, resulting in uneven air supply and uneven operation. The solution to this situation is to improve assembly accuracy.

6. Due to the bonding strength of coal, it cannot be stirred evenly in time.

In some places, coal sticks to lumps, resulting in uneven airflow distribution in the furnace and causing the furnace to be overheated.

7. Due to some defects in the gas generator itself, such as the grate rotation center and the furnace hearth are not concentric, the furnace hearth is not round, and there are leaks on the triangular bracket or water jacket, which will also cause deflection.
