Basic Introduction of Induced Draft Fan. |
Induced draft fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft of boilers and industrial furnaces; cooling and ventilation of air conditioning equipment and household appliances; drying and selection of grains; inflation and propulsion of wind tunnel wind sources and hovercraft, etc. The working principle of induced draft fans is basically the same as that of turbine compressors, but due to the low gas flow rate and small pressure change, it is generally not necessary to consider the change of gas specific volume, that is, the gas is treated as an incompressible fluid. |
