Abstract: An atomizer monitoring system monitors parts or components that are utilized in atomizers for flue gas desulfurization or in spray drying applications, taking into account each part's longevity, installation date, and expiration period, using wireless sensors and radio frequency identification (“RFID”) technology, whereby small, inexpensive RFID tags are placed on, or embedded in the atomizers, for example, in an atomizer wheel. The monitor system can avoid failure of parts within an atomizer and costly downtime associated with removal and replacement of parts that have reached their useful life. The preferred embodiment utilizes radio frequency identification (“RFID”) technology which is linked to a web-based data base.
