To avoid slagging in the gas generator, the following measures can be taken:

1. Choose reasonable equipment: Choose equipment with reasonable structure and fine workmanship, especially the coal adding system, to ensure uniform distribution.

2. Control the ash melting point of coal: Choose coal with an ash melting point greater than 1250 degrees. In this way, when the temperature of the material layer reaches 1100-1200 degrees, the ash will not melt and the possibility of slagging can also be reduced.

3. Control the amount of water vapor: Select a reasonable amount of water vapor according to the type and particle size of coal used. Excess water vapor may causegas generatorThe internal temperature drops, which affects the combustion and gasification effects of coal, thereby increasing the risk of slagging.

4. Control the temperature of the combustion layer: Controlling the temperature of the combustion layer below the ash melting point can avoid slagging caused by ash melting.

To sum up, by selecting reasonable equipment, controlling the ash melting point of coal, the amount of water vapor and the temperature of the combustion layer, slagging in the gas generator can be effectively avoided. These measures can ensure the normal operation of the furnace and improve the efficiency and quality of gas production.
