How caustic stress leads to failures of incinerator caustic spray nozzles

Maity, M., Al-Zahrani, E., Al-Meshari, A., SABIC Technology Centre

Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.
