Collecting plates are designed to receive and retain the precipitated particles until they are intentionally removed into the hopper. Collecting plates are also part of the electrical power circuit of the precipitator. These collecting plate functions are incorporated into the precipitator design. Collecting plates as well as discharge electrodes will tear, deform, wear or will be precipitated by dust (Coating). These problems will happen because of thermal stress, misalignment while hammer hitting, process parameter and ….
