The SHOCKSystem™ removes ash and platenization resulting in decreased primary superheater and economizer exit gas temperatures.   SHOCK STORY: PRIMARY SUPERHEAT DEMONSTRATION Current Situation: 600+ MW Boiler Burns a blend of Powder River Basin (PRB) and Bituminous Coal Heavily sintered platenization in the primary superheater (PSH) tube bundles leading to lower heat transfer efficiency in the PSH with resulting high boiler exit gas temperature Solution: Installed SHOCKSystem™ between the upper and lower primary superheater bundles Utilized an existing manway opening on the east wall Performance: Operation resulted in significant ash collection in hopper; indicating successful removal of built up ash from primary superheater Video confirmed built up platenization was removed from the gas lanes SHOCKSystem's™ Bottom-Line Impact: Holding hopper loading indicated significant ash removed Local instrumentation data showed decrease in primary superheater exit gas temperature by 45°F Plant data showed east side economizer exit temperature was lower by 5°F to 10°F compared to west side Photo survey indicated platenization was removed from primary superheater tube bundles Led to a proposal for installation   Results: Removal of Built Up Ash From Horizontal Reheater Before SHOCKSystem™ After SHOCKSystem™ Significant platenization between 18th and 19th row from top of Superheater prior to SHOCKSystem™ Significant platenization between 2nd and 3rd row from top of Superheater prior to SHOCKSystem™ Removal of platenization between 18th and 19th row of Superheater Removal of platenization between 2nd and 3rd row of Superheater     < Horizontal Reheater Demonstration Shock Stories Index Superheat Slag Removal >     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.
