The omni-directional blast wave created by the SHOCKSystem™ removes ash deposits that cannot be removed by conventional cleaning technologies such as sootblowers.   THE CLEANING PROCESS The SHOCKSystem™ generates a detonation-based supersonic hemispherical pressure/blast wave that propagates in all directions within the boiler providing non-line-of-sight cleaning, unlike conventional cleaning technologies.   SHOCKSystem™ blast wave interacting with fouled boiler tubes Before Blast Wave After Ash bridges built up on tube rows prior to blast wave Blast wave entering boiler and removing ash bridging Significant cleaning seen after blast wave dissipates   This omni-directional blast wave removes ash deposits that cannot be removed by conventional cleaning technologies such as sootblowers. The cleaning radius of the blast wave in an economizer is nominally in the 20' to 25' range for a single SHOCKSystem™ combustor. This range may vary depending on the coal properties and the local gas temperature. In most instances an individual combustor can replace, or reduce the use of, two to four sootblowers.   Computational Fluid Dynamics (CFD)     Gas Flow Improvement Bridging and Platenization No Bridging or Platenization As shown in this graphic, bridging and platenization severely impede gas flow around boiler tubes. The blast wave produced by the SHOCKSystem™ removes bridging and platenization, allowing gas to flow freely.   < The Detonation Process Index Components and Installation Flexibility >     Email us to learn more about our next generation ash removal product.   PW Privacy Policy  |  PW Terms + Conditions  |  PW Site Map         Boiler Cleaning News       SHOCKSystem™ Receives Gold CQIA Designation     AEP Rockport Purchases Second SHOCKSystem™     EnergyTech: SHOCKSystem™ Reduces Erosion (PDF)     Energy Central: Backpass Cleaning Comparison (PDF)     Power: Harnessing Detonation Waves (PDF)     EnergyTech: Advanced Sootblower Technologies (PDF)     Power: Shockingly Clean Boiler (PDF)     [ Boiler Cleaning News Archive ]       Shock Literature       White Paper: Tube Erosion     Detonation-Based Online Cleaning     Comparison: Acoustic Horn vs SHOCKSystem™     Comparison: Sootblower vs SHOCKSystem™     Meets Local, State and National Safety Regulations     [ Literature Archive ]       Shock Stories       Backpass Ash Platenization Removal     Economizer Demonstration     Economizer Demonstration     Economizer Demonstration     Economizer Bridging and Platenization Removal     [ Shock Stories Index ]       Pulse Detonation News       Popular Science: After Combustion - Detonation     Flight International: Pulse Power     Aviation Week: Taking the Pulse     [ Pulse Detonation News Archive ]       Shock Video   Span shot of shock tube extending into boiler region with use of combustor bend [mpg size: 498 KB]     Support hangers and combustor bends give the SHOCKSystem™ installation flexibility [mpg size: 563 KB]     Shock Pics   Five-picture time-elapsed series of ash removal in boiler region.
