Abstract
A system includes an electrostatic precipitator, an electromagnetic sensor and a processor to locate spark locations. The electromagnetic sensor is used at various locations of the electrostatic precipitator to obtain data and process the same for locating sparks in electrostatic precipitators.
Claims19
A system comprising:
- at least one electromagnetic sensor;
- a processing device operable to process data received from the at least one electromagnetic sensor, to estimate an electromagnetic field profile from the processed sensor data, the electromagnetic field profile comprising a mapping of information including a distance of the at least one sensor from a power source mapped against an electromagnetic field intensity transduced at the distance, and to determine a location of a spark within an electrostatic precipitator (ESP) using the estimated electromagnetic field profile.
A method comprising:
- obtaining electromagnetic field data from above an electrostatic precipitator (ESP) from at least one electromagnetic field sensor;
- processing the obtained electromagnetic field data to determine an electromagnetic field profile therefrom, the electromagnetic field profile comprising a mapping of information including a distance of the at least one electromagnetic field sensor from a power source mapped against an electromagnetic field intensity transduced at the distance, and
- using the electromagnetic field profile to determine a location of a spark.
