Slurry Atomization Anomaly Detection in Spray Dry Absorbers
Presented by: Stewart Nicholson – Primex Process Specialists
Many dry scrubbers are equipped with dual fluid nozzle systems for slurry atomization. Nozzle malfunction in these systems can compromise slurry atomization resulting in excessive material accumulation in SDA hoppers, ductwork and fabric filters. Related effects on safety, reliability and operating cost can be substantial. At one facility, material accumulation within the SDA hoppers decreased significantly after implementation of a new method to detect nozzle malfunction. When combined with other operational improvements, this detection method has also helped reduce lime consumption, fly-ash production and maintenance costs. This paper will be presented as a case study describing the situation, solution, results and lessons learned.
Advanced Monitoring in Tight Windows
Presented by: Michael-Paul Jenkins – Gecko Robotics
What if there was a better way to monitor vessel thickness in scrubbers in between major outages?
Failure of dry scrubbers in the industry are well documented. We know that these vessels are exposed to corrosive and erosive environments in normal operating times. To get ahead, many utilities monitor wall thickness in spot checking during maintenance outages. These outages are usually very quick and because of this, not everything that should be monitored, can be. Time, funds, and access prohibit thorough inspections.
However, what if there was a way to monitor dry scrubbers in these tight windows that can not only monitor wall loss, but also lend insight into causes and possible solutions?
This presentation will cover the history and modern take on monitoring assets within tight turnarounds/windows, explore Rapid Ultrasonic Gridding (RUG) for liners, identify advantages and disadvantages of robotic inspection methods, and cover a case study with advanced monitoring and data-dense inspections.
