Question: When calculating the wind pressure of an exhaust fan, what is the gas temperature indicated on the fan’s nameplate? 20℃ or 200℃
I saw on the internet that the rated temperature of an exhaust fan refers to its design temperature; 20°C is supposed to be the ambient temperature. I’m not sure where the value of 20°C comes from Please give your advice
Hehe, you’re right – 20°C or 200°C both make sense; I wonder what your intended use for it is. The flow rates at different temperatures are labeled differently.
It is the exhaust fan used for purifying flue gas from power plants; the temperature of the flue gas is 170 degrees℃
Then it should be 200°C, right?:lol
The gas temperature remains as it is; the fan provides the flow rate under operating conditions. The temperature is the operating condition temperature
This design manual for small and medium-sized cogeneration plants specifies 20°C, while equations 4-3 and 4-4 on pages 120–120 of the *Revised Textbook for the National Examination for Registered Public Equipment Engineers in the Power Field* (2nd edition) specify 200°C; it is likely that one of these values is incorrect
Just call the manufacturer to verify it, and you’ll have a conclusion!
