The drum induced draft fan is a driven fluid machine, which is a machine that relies on the input of mechanical energy to increase the gas pressure and discharge the gas. At the same time, it is also a kind of fan, it does not need to consider the change of gas specific volume, because its working principle is basically the same as the turbine compressor, but because the gas flow rate is low, the pressure does not change much.

Drum induced fan features:
Drum induced draft fan is mainly determined by the parameters of flow, pressure, power, efficiency and speed. Here we explain the meaning of these parameters respectively: the flow is also called the air volume, it is determined to be the gas volume, expressed in terms of the volume of gas flowing through the fan per unit of time; the pressure is also called the wind pressure, there is static pressure, dynamic pressure and full pressure The division refers to the increase in the pressure of the gas in the fan; the power refers to the input power of the fan, ie the shaft power. The ratio of the effective fan power to the shaft power is called efficiency. The total pressure efficiency of the fan can reach 90%.

The role of drum induced draft fan:
The fan has a wide range of applications. It is not only used in industrial and construction applications. It is also popular in agriculture and life.

From this we can detailed divided into five application areas:
1. Fans are widely used for ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings;
2. Ventilation and induced draft of boilers and industrial furnaces;
3, cooling and ventilation in air conditioning equipment and household appliances;
4, drying and delivery of cereals;
5, wind tunnel wind source and hovercraft inflatable and advancing.
