Impact of overloading operation in GE coal-water slurry gasification on refractory bricks
Thread Content
The impact of overloading the gasification furnace on refractory bricks. Could everyone help analyze it from the perspective of the mechanism of action?
Generally, the impact is not significant; one needs to consider the properties of the ash in coal, such as its melting point, and conduct a comprehensive calculation. . . . . . . . . . . . . . . . . . . .
Regardless of the load level, there are only a few areas where refractory bricks tend to wear out easily. The area where the vault meets the cylinder wall, and also the few rings of bricks at the base of the cone near the slag outlet. Other local issues generally aren’t too serious; factors such as the atomization angle, operating temperature, ash content, and load level only have a certain impact on the service life. As for just how great the impact is, it’s really hard to say; all of these factors influence each other, and in many cases it’s not caused by a single factor alone.
The excessive airflow results in high intensity, a large number of solid particles per unit volume, and increased wear. Secondly, the brick joints are also greatly affected. Due to the high load on the gasification furnace, the gas flow rate inside it increases, which has a significant impact on the brick joints.
