The pulse detonation technology behind the SHOCKSystem™ successfully removed bridging and platenization.
SHOCK STORY: ECONOMIZER BRIDGING AND PLATENIZATION REMOVAL
Current Situation:
800+ MW boiler
Burns 100% Powder River Basin (PRB) Coal
Bridging and platenization cause dramatic decline in Delta Temperature (DT) within three months after each economizer cleaning outage
Solution:
Install a single combustor between the lower and upper Economizer bundles
Utilize an existing manway opening on the boiler sidewall, 7' from the backwall
Performance:
Analyzed ash accumulations in the hoppers directly below the economizer
After the SHOCKSystem&trade operation, hoppers took longer to empty and tripped a "High Vacuum" alarm signifying more than usual ash removed between hopper emptying cycles
SHOCKSystem's™ Bottom-Line Impact:
Improves Economizer Delta T
Reduces local sootblower use
Eliminates need for offline cleaning service
Lead to an installation proposal
Results: Bridging and Platenization Removed
Before SHOCKSystem™
After SHOCKSystem™
Significant bridging and platenization is visible in tube bundles prior to SHOCKSystem™ Online Detonation Cleaning™.
The SHOCKSystem's™ pulse-detonation technology successfully removed bridging and platenization.
