Boiler fan process
Thread Content
Hello everyone. I’m not very familiar with boiler operations; please help me out if I encounter any problems on site. In the coal-based processing process, do the fans used to supply air to the boiler serve to assist in combustion? ? ? The most important thing is, for example, for a square duct with dimensions of 2000*1600, what is an appropriate air volume? What is a suitable maximum flow rate for the fan? And what is the typical operating pressure?
The wind speed in flues is generally less than 15 meters per second; therefore, a value of around 14 meters per second is usually chosen. By determining the cross-sectional area, it is possible to calculate the air volume. The operating pressure is generally in the range of 5000–6000 Pa.
It’s just the right time to learn*,*,*,*,*,
We aim for a higher value, at 20 m/s; the head loss is related to the frictional loss along the flow path. We use 1500Pa.
It should be at 20M/s; if the wind speed is low, dust tends to accumulate.
