87. What are the hazards of high inlet temperature in the flue gas system for the unit?
When the inlet temperature of the smoke extractor is high, the temperature of the moving blades in its rotor increases, which reduces the allowable stress of the blade material. When the centrifugal force generated by the rapidly rotating blades, combined with the stresses arising from operation, exceeds this allowable stress, the blades can be severely damaged or even fly off, leading to serious consequences.
