What are Grade A and Grade B operation of gasification?
Thread Content
As the title suggests, I would like to understand the concepts of Grade A and Grade B operation in gasification. Are there any other grading systems as well? I appreciate any suggestions you can provide. Thank you
Here, Grade A operation refers to continuous, uninterrupted operation, while Grade B operation involves continuous feeding without removing the burner (starting up immediately after shutting down). I’m not sure if that’s what you mean.
Grade A operation presumably means that the gasification furnace operates continuously with feedstock supplied for production, while Grade B involves short interruptions during operation, but these interruptions do not last more than 24 hours before production resumes with feedstock supplied again
I am very grateful for the answers from both of you. I also looked up some information yesterday: Grade A operation means continuous, uninterrupted operation, while Grade B means operation is suspended for maintenance and repairs within 24 hours before resuming. The factory logos of various units may differ slightly, but the basic meaning remains the same. Thank you again to all the kind people
