1. A method for detecting power plant equipment overheating, comprising: remotely sampling in real time a plurality of types of overheating detectors that are actively monitoring power plant equipment; storing at least one output sample reading from each respective type of overheating detector; determining in real time a likelihood of whether a combination of the stored types of detector output sample readings is indicative of monitored power plant equipment overheating by performing the following steps in any order: referencing previously stored information that associates respective types of detector sample reading levels and with equipment overheating; comparing at least one stored sample reading from each respective type of overheating detector with respective stored association information relevant thereto to determine make respective first overheating determination confidence levels; comparing a combination of the at least one stored sample reading from each respective type of overheating detector with respective stored association information relevant thereto, if such combination information is available, to determine at least one second overheating determination confidence level; and combining all desired confidence levels information to derive an overall confidence level of whether the power plant equipment is overheated.
