How long is the operating cycle of a gasification furnace?

How long is the longest operation cycle? How do you determine when to switch to another furnace in the later stages? How to bake the furnace for newly put into operation ones
It depends on whether it is a fixed-bed； Fluidized bed or pneumatic bed.
The operating cycle of a fluidized bed is generally the lifespan of the nozzle, which is about 100 days.
Yes, generally it’s necessary to check the burner; after around 100 days, the burner is ready and the furnace can be used again. For newly commissioned furnaces, they need to go through a drying process according to the specified drying curve. Additionally, once the furnace starts operating, it’s necessary to adjust the process parameters and take into account the condition of the trays in the water washing tower; in such cases, the furnace may need to be shut down quite soon

The burner is the key indicator to consider; in addition to the burner, the operating condition of the system is also an important factor to take into account. The service life of the burner is not necessarily around 100 days either; if inferior coal types are used or the quality of the coal slurry is poor, the burner will wear out more quickly, and it may be necessary to replace it as early as after one month. Therefore, close attention should be paid to the burner pressure difference – this value represents the pressure difference between the coal slurry pipeline and the combustion chamber of the gasifier, and it serves as an indicator of the degree of wear on the burner
BGL 239. The runtime still requires continuous exploration and research to address the issues that arise during operation.
