103. What are the hazards of high inlet temperature in the flue gas system for the unit? How should it be addressed?
What are the hazards to the unit when the inlet temperature of the exhaust fan is high? A high inlet temperature leads to an increase in the temperature of the rotating blades of the exhaust fan, which in turn 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 break off, resulting in serious consequences. Solution: When the flue gas temperature is above 680°C, contact the reaction unit to reduce the temperature.
A high inlet temperature of the smoke extractor will raise the temperature of its rotor and blades, thereby reducing the allowable stress. When the temperature reaches a certain level, it is possible for the rapidly rotating rotor to be damaged and the blades to break off. When the flue gas temperature is above 680°C, contact the reaction unit to reduce the temperature.
According to the instructions, the design temperature of the smoke extractor generally does not exceed 683°C, and this is determined by the material used for its components. Prolonged overheating can cause damage to the components of the flue gas exhaust system, and in such cases it is necessary to rapidly cool down the flue gas.
