For thermal power plant, soot accumulated on heating surface would cause big problems. It would reduce boiler thermal efficiency, increase fuel consumption. Sometimes, unscheduled shutdown occurs, because flue pass is blocked and tube failure happens. There are many different ways for boiler cleaning, such as steam soot blower, sonic horn, pneumatic pulse cleaning, shock wave cleaning. Mechanical boiler rapping system by tumbling hammers is widely used for waste heat boiler (especially for SP boiler in cement plant), biomass boiler, MSW boiler, etc.
Mechanical rapping system could clean soot deposits on platen heating surfaces and tube bundles without need for medium like steam, compressed air, etc.
Rapping hammers are connected to a rotating shaft driven by motor and gear unit. When the hammers are lifted, they gain potential energy, which is transferred into great impact energy when falling hammers collide with a beam. The force applied to beam will cause vibration of tube bundles, and shake off soot build-up. Weight and mounting arm length is closely related with impact force.
