The steam turbine underwent 25,000-hour maintenance, high and medium voltage electrical installation inspection and maintenance were performed, and mechanical, electrical and instrumentation maintenance of waste feeding, waste incineration, flue gas and waste water treatment unit equipment was carried out. The insulation in the secondary combustion chamber and boiler area was removed, scraped and painted, with all insulation renewed.

NUMEROUS MAINTENANCE OPERATIONS PERFORMED

The facility's rotating equipment such as motors, compressors, pumps and fans, as well as cranes and conveyor systems underwent maintenance and inspection. Measurement equipment including pressure, level, speed and temperature instruments were inspected, cleaned and maintained, and fire protection system inspection and maintenance was performed. Flue gas emission equipment inspection and maintenance, piping systems, tank and unit floor coating, epoxy and ebonite repairs and renewal, kiln and boiler manhole renewal, dioxin unit stainless steel filter and base plate renewal, condenser and cooling water unit cleaning with 500-bar air jets, boiler tube surface cleaning and boiler ash discharge system maintenance, scaffolding installation and dismantling due to work at height, pressure equipment pressure testing and renewal, and numerous other maintenance operations were performed.

"FIRST-TIME INTERVENTION"

In the successfully completed planned major maintenance, certain critical areas were also addressed for the first time. A 7% inclination that had developed in the secondary combustion kiln emergency flue section was successfully corrected through very comprehensive and technical work during this maintenance. Defective plates on the kiln side walls were replaced, and axis misalignment present in the steam boiler super heater collectors was also corrected during the major maintenance process. Insulation in the boiler radiation and steam heating zones was removed, corroded sections were repaired, and the Venturi, Lime and FK treatment facility floor epoxy coatings and grilles were renewed.
