Abstract
The invention relates to a monitoring apparatus (312) for a steam plant, the apparatus comprising: a vibro-acoustic sensor (311) associated with a component of the steam plant, the sensor (311) being configured to provide an output indicative of the operating condition of the component; and a condition monitoring unit (313) coupled to the sensor (311); wherein the condition monitoring unit (313) is configured to analyze the output of the sensor (311) in order to identify characteristics attributed to live steam and characteristics attributed to condensate and to estimate steam leakage and condensate load for the component based on the identified characteristics. The invention also relates to a corresponding method of monitoring a steam plant.
