Rapper ControlsDevices, generically called rappers, are used for cleaning the internals (collecting plates and discharge electrodes) of the precipitator. ![]() The rapper control energizes these devices for a programmable time period and intensity. The time period and intensity have a direct affect on the efficiency of the precipitator. ![]() Redkoh’s MRC-NT microprocessor based rapper control is the most flexible control on the market. Clock timing (repetition time) by Individual rapper groups, or globally is provided. Rapper intensity (plunger lift) can be adjusted by individual rapper, by rapper group, or globally. Six independent rapper programs can be stored for use under varying operating conditions (such as low load, various fuels, boiler tube leak, etc.).
Rapper controls should be evaluated every ten years or so to make sure they are up to date and contain the latest strategies for optimal precipitator cleaning. New controls for back fitting into existing rapper control cabinets can be provided as well as new controls and cabinets.
