Gasifier Refractory Brick Life

In order to protect the outer steel shell from high temperature, erosion, and corrosion, the gasification chamber is lined with refractory bricks. Furthermore, the coal 

In summary, the main reasons for the refractory failure in gasifiers include high temperature, large and quick temperature changes, erosion by particulate, molten slag attack, slag variation from the feedstock, hot corrosive gases, and alkali vapor attack.48 

The replacement of refractory bricks is very expensive hence, some gasification plants must have a spare gasifier as a backup for the gasifier shutdown schedule, such as brick and nozzle replacement. Refractory brick failure is one of the major problems for gasifiers to achieve high reliability, availability, and maintainability.47
