Corrosion of incineration equipment is a significant factor that hinders the long-term stable operation of hazardous waste incineration systems.This study utilizes scanning electron microscopy to examine coke in various sections of the hazardous waste incineration system and employs an energy spectrum analyzer to analyze the main components of coke in these sections.Based on this analysis,the causes of coking products in different parts are investigated.The findings reveal that O,F,and P are the primary oxidizing elements,while Ca,Sb,and Fe compounds are the main constituents contributing to coking at the end of the kiln.In contrast,sulfur(S)and oxygen(O)dominate as oxidizing elements in ash residue at the exit of the secondary combustion chamber,resulting primarily in sulfur salt compounds during coking.There are obvious differences between the two sections,which can provide valuable insights for implementing corrosion prevention measures across different sections within an incineration system.
