With lower maintenance and operations costs, and greater installation flexibility, the SHOCKSystem™ outperforms Sootblowing technology.   Sootblower Cleaning vs. SHOCKSystem™ Online Detonation Cleaning Comparative highlights between technologies Online Detonation Cleaning™ Sootblower Cleaning Ominidirectional-propagating blast wave Line-of-sight jet Single impulse 6 minute cycles 2 PSI minimum Tens of PSI PIP 10 pulses repeated every 8 hours per combustor (30 cycles per day) 1 cycle every 4 hours per sootblower (6 cycles per day) Successful in continuous-maintenance mode and remedial cleaning mode – established deposits are removed as well. Used principally in continuous-maintenance mode – does not let ash accumulate or sinter on adjacent three to four tube rows.   The SHOCKSystem™ employs Pulse Detonation Technology The SHOCKSystem™ Detonation Based Online Boiler Cleaning Technology is NOT a Jet-Interaction Sootblower   Maintenance Comparison SHOCKSystem™ Requirements The SHOCKSystem™ has limited moving parts 1) Replace fuel and air filters 2) Replace combustor spark plug 3) Ensure Fuel Supply is Ordered each Month   Sootblower Cleaning Inspect And Replace On A Regular Basis ... 1) Blown and damaged nozzles 2) Warn and damaged carriage housing 3) Warped, melted, corroded lance tubes 4) Entangled cable and power cords 5) Worn and failed gearbox shields 6) Grooved feedtubes 7) Unaligned and broken feedtube locknut assemblies 8) Adjust blowing pressure to match boiler conditions 9) Tighten packing tensioner to eliminate leaks   Generic Operating Cost Comparison Cost Per Single Sootblower or Combustor Air Sootblower Steam Sootblower SHOCKSystem™ Combustor Flow Rate 5100* scfm 12,000* pounds/hr Proprietary Info.

Rockport U2 Economizer 4 Steam Sootblowers: 2 on North side wall 2 on South side wall 5 SHOCKSystem™ Combustors: All five combustors located along front wall, with direct access to problem region. Economic Benefits Cost of operating five SHOCKSystem™ combustors at AEP Rockport is 91% lower than cost of operating four steam sootblowers located above the middle economizer bundle.   Installation Flexibility SHOCKSystem™ - SHOCKSystem™ can be installed along any boiler wall - SHOCKSystem™ can bend, turn and avoid any obstacles - Bent tube configuration requires less than 10' space from boiler wall - Nested tube configuration offer another method of minimizing footprint - Straight tube configuration can be placed in existing sootblower locations   Bent tube Configuration Nested tube configuration Straight tube configuration Requires less than 10' of space, allowing installation in tight quarters Two nested combustors can be installed in less than 10' of space Straight tube configuration requires less than 15' of installation space   SHOCKSystem™ Installations vs. Sootblowers Installation Benefits The SHOCKSystem™ has multiple installation configurations that allow the flexibility to install on any boiler wall to combat fouling and fly-ash accumulation       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.
