Boiler centrifugal induced draft fan G4-73 High pressure dust collector fan Industrial plant axial flow fan
Centrifugal induced draft fan is an important ventilation equipment, which mainly relies on the mechanical energy input by the motor to increase the gas pressure and send gas simultaneously. The following is a detailed introduction to the centrifugal induced draft fan: 1. Definition and working principle The centrifugal induced draft fan is driven by the motor to rotate the impeller, so that the air is sucked in and thrown out along the flow path of the blade under the action of centrifugal force, so as to achieve the purpose of ventilation, air exchange and exhaust. Its working principle is similar to that of a turbine compressor, but because the gas flow rate is low and the pressure does not change much, the gas is usually treated as an incompressible fluid.
Centrifugal induced draft fans are usually divided into different types to adapt to different use scenarios and needs. Its structure mainly includes impeller, shell, air inlet, air outlet, bearing and motor and other components. Impeller is the core component of centrifugal induced draft fan, and its shape and size directly affect the performance of the fan.
Centrifugal induced draft fans have a wide range of applications in many fields, including but not limited to the following aspects: Industrial field: In metallurgy, chemical industry, light industry and other industries, centrifugal induced draft fans are used for ventilation, exhaust gas emission and material transportation and other scenarios. For example, in the chemical industry, centrifugal induced draft fans can be used in production equipment such as chemical reactors and distillation towers to transport steam through pipes to heating furnaces to improve heating efficiency and reduce energy consumption.
Construction: In large commercial buildings, factories and offices, centrifugal induced draft fans are used as ventilation devices to keep indoor air circulating and fresh. For example, in buildings consisting of multi-storey factories, centrifugal induced draft fans can be used to send harmful gases such as nitric acid, oxygen, etc. to the discharge system.
Other fields: Centrifugal induced draft fans are also used in aviation, tunnels, mines and other fields. In aviation, centrifugal induced draft fans are used in the power systems of aircraft to provide the required gas or air.
