Selection of combustion air fans
Thread Content
To upgrade the equipment, the company needs to purchase a new combustion air fan with a maximum flow rate of 17,000 Nm3/h. The operating conditions are a temperature of 450 degrees and a pressure of 10 kPa. I would like to ask what capacity fan should be chosen? ? ?
Choose a 316L stainless steel heat blower, such as those produced by Jilin Siping Blower Factory. For details, please consult the manufacturer!
Select the model based on your wind pressure and air volume; remember that the actual air volume should be calculated by multiplying the maximum air volume by a factor of 1.15. It’s ideal to have a damper available, as it allows for arbitrary control of the air volume
For the upper floor, the actual air volume should be calculated by multiplying the maximum air volume by a factor of 1.15. Is the maximum air volume referred to here the value indicated on the machine’s nameplate? The factor of 1.15 represents a design margin; please provide an answer
The parameters of the fan (rated wind pressure, rated flow rate) are series values specific to that model. After determining the maximum flow rate required by the operating conditions, select a value from the series of models whose parameters are closest to that value, provided that it is greater than the required maximum flow rate. LZ mentions that the temperature of the medium is 450°C, and ordinary carbon steel cannot be used for this. 0Cr18Ni9 or other heat-resistant materials can be used optionally.
Why is the temperature of your combustion air fan so high? Normally, the temperature of such fans doesn’t reach such levels. Are the airflow volume and pressure requirements applicable at 450 degrees Celsius or at normal temperature? You can send me an email to communicate; give me the parameters and I can help you choose the appropriate fan. I can also take a look at any fan chosen by others to see if it’s suitable, hehe
