Burns a blend of Powder River Basin (PRB) and Bituminous Coal.
Accumulated ash deposits and pluggage of the economizer results in frequent offline cleaning of the economizer.
Severe vertical platenization exists in the lower super heater region.
Pre-demonstration video survey revealed slightly fouled economizer and significant platenization in Lower Primary Superheater.
Solution :
Installed SHOCKSystem™ between Lower Primary Superheater and Economizer Bundles.
Utilized existing manway opening on the front wall near the west side of the boiler.
Performance :
SHOCKSystem™ operated intermittently for six days.
West delta temperature (DT) increased by 20°F-30°F during operation.
SHOCKSystem's™ Bottom-Line Impact :
Hopper loading was significant on the side of the boiler where the device was installed.
Gas temperature differential across the lower primary superheater and economizer on side where device was installed was higher by 20°F-30°F during operation.
SHOCKSystem™ demonstrated ash removal despite operating at low power and firing low number of shots.
West Delta Temperature Histogram :
24 hour period
Histogram shows during the SHOCKSystem™ operation period West Side gas temperature differential was higher than before SHOCKSystem™ operation period.
