By applying the diagnostic procedures discussed in Part I to some actual plants (a coal fuelled steam power plant, a combined plant running on natural gas and a steam cogenerative plant fed by solid wastes) significant results have been obtained. A software system has expressly been implemented and connected with plant acquisition and control devices. Operation data have been collected and processed, focusing on the main components failures (i.e. boiler, condenser and steam turbine stages) and on plant conditions after long periods without maintenance (hence highlighting wear and fouling effects on the overall performances). These tests allowed to validate the system modules and obtain useful information about sensitivity and applicability of the methods. The structure of the software and its available strategies to detect and weigh malfunctions are deepened in the paper.

Abstract
By applying the diagnostic procedures discussed in Part I to some actual plants (a coal fuelled steam power plant, a combined plant running on natural gas and a steam cogenerative plant fed by solid wastes) significant results have been obtained. A software system has expressly been implemented and connected with plant acquisition and control devices. Operation data have been collected and processed, focusing on the main components failures (i.e. boiler, condenser and steam turbine stages) and on plant conditions after long periods without maintenance (hence highlighting wear and fouling effects on the overall performances). These tests allowed to validate the system modules and obtain useful information about sensitivity and applicability of the methods. The structure of the software and its available strategies to detect and weigh malfunctions are deepened in the paper.
