The corrosion of sulfur recovery apparatus was one of the important factors affecting the long-term and safe operation of the unit.The three-stage sulfur condenser leaked frequently due to various reasons such as manufacturing quality of equipment,poor quality of steam drum water,significant fluctuations in load,and corrosion during start-up and shutdown.In recent years,corrosion problem of the three-stage sulfur condenser was solved by quality monitoring of equipment manufacturing,quality control of furnace water to ensure good process anti-corrosion,stable production to reduce load fluctuations and proper protection of de-vices during start-up and shutdown periods.
