Directing against problems occurred on cathode of electrostatic preciptators(EP)for boilers of two supercritical 500 MW units in Huaneng Yimin Power Plant
such as troubles frequently appeared in motor-reducer rapping system
and inconvenience in repair and maintenance etc.
a pneumatic rapping system
including actuator cabinet and atomatic tripping facility has been developed
and the original rapping system being retrofitted according to the newly developed pneumatic rapping system.After retrofit
the rapping equipment uses compressed air as motive force
