ABSTRACT:
A system and method for detecting hot spots in a rotary regenerative air preheater which compensates for normal variations in the temperature of the incoming hot gas stream or incoming cold air stream. Alarm conditions are based on calculations relating to the average and maximum outlet gas or outlet air over a period of time compared to the air and gas inlet temperature. The alarm is triggered if the maximum values deviate from the time averaged values more than a selected percentage.
