High Temperature Fans for Dust Collecting

The smoke exhausting from boiler by centrifugal fan enters into the dust collector, impacts the water at high speed, most dust particles stay in the water due to the weight increase or sticking to water, this is impingement stage.

At this time, because of the gas movement, the water form a parabola-shape drop, spray, and bubble area, then the dusty gas is purified further in this area, and this is a water bath stage.

Large Airflow Backward Curved Fans

What is more, when the high temperature gas enters into the dust collector, the water and gas will form water spray, the dust particles change flow direction, further purification when moving forward, this stage is nebulization dust collector.

Through the above three ways purification, clean gas from dust collector flow to the chimney.

Xianrun Blower Centrifugal Fan for Inertial Dust Separator

Inertial dust separator is also called idle type dust chamber. Because the dust and gas in the air movement have different inertia force,the dusty gas collides baffle and dramatically changes the airflow direction, separating and collecting dust by inertia force according to motion trail.

Custom heavy Duty Industry Fan from China Supplier

Inertial dust separator has two kinds, collision type and rotary type. The former is install one baffle or multichannel baffle along the flow direction, dusty air collides the baffle, then dust particles separate from the gas.

Obviously, the higher speed of the dusty gas before collision the baffle, the lower speed after collision, the less dust, higher dust removal efficiency is higher.
The latter is that the dusty gas changes flow direction for many times, then separate dust in steering process.The smaller curvature radius of gas, the more steering speed, the higher dust removal efficiency.

High Temperature Industrial ID Fans for Boilers

The most energy saving and power consumption are main fans in coal power plant.
Fan frequency converter controls and adjust fans according to furnace pressure, wind speed, air volume, temperature, and etc., to meet the technological requirements and operation condition.

In the past without frequency converter, the industrial fans control the airflow by controlling the adjusting door and baffle, and centrifugal fan motors has been running at maximum power condition regardless of the production size demand.

In this case, not only production precision is restricted, but also causing a lot of energy waste and equipment loss, and leading to the production cost increases, shortening equipment service life, high maintenance cost to motor and mechanical transmission, and other electrical equipment.

Wear Resistant ID Fan

Most industrial fans and blowers use asynchronous motor and direct drive operation, so will cause large starting current, mechanical shock, electric protection features and so on. All these will affect the equipment service life, and it can not snap action protect equipment when there is mechanical failure, even pump damage and motor burning out.

For the high power motor, no matter directly start or star triangle start, will have varying degrees impact on power grid, so State Grid Corporation of China regulation is that the large current devices are not allowed direct start.
