What are the main faults of water-coal slurry gasification burners? It would be good to have approximate statistics
Thread Content
An important factor affecting the operating cycle of coal-water slurry gasifiers is burner failure. But what are the components where failures occur most frequently? Don’t central oxygen nozzles tend to have problems? Is the wear mainly concentrated on the inner surface of the outer ring? Near which part? What percentage does each account for in the failure rate of cooling water jackets and pipes? I hope experienced manufacturers can share some information.
The center oxygen nozzle has the fewest failures； The outer epoxy and cooling water coils are mainly subject to high-temperature ablation ； The inner ring suffers severe slurry erosion. There are also others such as so-called sulfur corrosion and intergranular corrosion.
I’ve learned about this – why can the lifespan of nozzles abroad be measured in years, while those in China can only be measured in hours? What is the main reason for this?
Calculated on an annual basis????;P ;P
Most shutdowns are caused by the rupture of the coil; generally, the outer ring head wears out, while the central oxygen nozzle rarely experiences problems. However, the service life is closely related to production.
