Incinerator induced draft fan
Thread Content
For a furnace’s exhaust fan, should one choose one with high flow rate or high pressure? ? ?
Both flow rate and wind pressure need to be taken into account; it’s not true that the higher they are, the better.
Flue gas flow rate and furnace negative pressure are the most basic requirements; in addition, other factors such as variable load, wear, and corrosion must also be taken into account.
It is best to have appropriate air volume and pressure; in addition to the flue gas flow rate, the specific conditions of the incinerator also need to be taken into account. When burning hazardous gases, the residence time in the furnace must also be considered (this should be planned in advance)； Regarding pressure, it depends on the type of furnace; however, in my personal opinion, a higher value is better (taking into account the combined resistance from the furnace itself, other auxiliary equipment, and flues).
Both air volume and flow rate need to be taken into account, with a certain margin reserved in accordance with standards. If the fan does not provide sufficient output, the boiler cannot operate at full capacity.
When selecting a design institute, it is necessary to ensure that sufficient negative pressure is available for imports
