First Claim
Patent Images
1. In an electrostatic precipitator having an electrode assembly and a rapping means for dislodging dust accumulations from said electrode assembly, said rapping means including a hammer movable through operating cycles for periodically delivering an impact blow to said electrode assembly, the improvement comprising:
- detecting means operatively associated with said rapping means for sensing hammer movement through said operating cycles and for generating control signals in response thereto; and
monitoring means operatively associated with said detecting means for indicating, in response to the discontinuance of said control signals, the failure of said hammer to move through said oerating cycles.

Abstract
An apparatus and method for monitoring electrode rapper operation in an electrostatic precipitator. The actual movement or impact of the hammer in an electrode rapper is sensed and a control signal is generated and transmitted to a monitor in response thereto in order to produce an immediate and accurate indication of rapper failure.
