The SHOCKSystem™ successfully removed platenization from horizontal reheater tube bundles, resulting in increased reheater gas temperature and overall cleanliness.   SHOCK STORY: HORIZONTAL REHEATER DEMONSTRATION Current Situation: 650+ MW Boiler Burns a blend of Powder River Basin (PRB) and Bituminous Coal Ash deposition in the horizontal reheater causes:     - tube leaks in the reheater due to sootblower erosion leading to forced outages     - draft loss     - increase in boiler exit gas temperature Solution: Installed SHOCKSystem™ between middle and lower horizontal reheater bundles Utilized an existing manway opening located on the west wall Performance: First two days of operation resulted in significant ash collection in holding hopper; indicating successful removal of built up ash from horizontal reheater SHOCKSystem's™ Bottom-Line Impact: Photo survey indicated removal of platenization from horizontal reheater tube bundles Holding hopper loading indicated significant ash removed from horizontal reheater tube bundles Gas temperature differential across middle and lower reheater increased during SHOCKSystem™ operation by 20°F to 30°F Economizer exit gas temperature on SHOCKSystem™ side decreased by 10°F to 20°F compared to other side Horizontal reheater cleanliness factor increased noticeably during SHOCKSystem™ operation Led to proposal   Results: Removal of Built Up Ash From Horizontal Reheater Before SHOCKSystem™ After SHOCKSystem™ Boiler's use of Aquatech technology failed to solve its platenization problem in horizontal reheater tube bundles.
