Reduction of Maintenance Costs and Improved MTBR of Boiler Steam Drum and Superheat Safety Valves (Room 317)

The goal of this project was to reduce the cost of maintenance and repair of the safety valves on all six boilers located at the Burns Harbor mill. Historically, the practice has been to disassemble and replace the parts for every valve annually. Studies have shown that the majority of the valves that are disassembled do not require a total disassembly and repair. OSHA states that each company will establish a good engineering practice on the frequency and type of repair based on the historical data collected. By changing the frequency and the type of testing, we are increasing the time between repair from one year to two years.
