Improve service life for off-gas systems thus increasing the number of heats between shutdowns.
The Skirt Seal Tank is a critical item in the BOS off-gas system. It is crucial in preventing the escape of waste gas during the lowering and raising of the skirt section. Historically, the skirt water seal tank was regularly cleaned out during scheduled shutdowns.
Improvement to other functions in the system, has meant that the length of time between shutdowns has increased. This has led to a buildup of sludge and debris, caused damage to the skirt seal plate and prevented the skirt from being fully lowered, thus negating a proper gas seal in the off-gas system.
Wilbartec developed an innovative seal tank flushing system which operates without valves or complicated control systems.
The new configuration utilises a self flushing pipe arrangement which frequently self-cleans, thus preventing excessive debris accumulating in the water seal tank during its operation.
Wilbartec designed a system that achieved immediate & ongoing maintenance cost & time reductions for BlueScope Steel.
