Abstract

In this paper, axial flow fans which applied at coal-thermal power plant(500[MW]) cause a unique phenomenon called 'Stall' under normal operation and this causes abnormal operation and damages the blades. In order to prevent these abnormal operation, this study estimates the reliability of new system which is applying control logic on each parameter with existing black-box-type by field test.
