Are you planning to buy an industrial fan? You must know that it is used for large-scale industries. High-capacity heavy duty industrial fans are inexpensive that provide high pressures of airflow. Heavy-duty industrial fans are desired because of their high pressure and volume outputs. Large industries need two or more centrifugal fans to operate efficiently. However, it is not possible to install multiple plans for various purposes. Due to the restricted amount of space in the working area, it might not be practical.
Therefore, one heavy-duty centrifugal fan with a high-power rating is enough to meet the demands of large-scale operations. There are two primary types of heavy-duty fans used extensively in industries. We will learn about these industrial fans in this article.
Two Popular Types of Heavy-Duty Industrial Fans and Their Applications
1. Double Inlet Centrifugal Fans
The double-inlet centrifugal fan delivers high-speed airflow for industrial processes. These heavy-duty industrial fans are specially designed to handle gases and withstand harsh operating circumstances.
How does it work?
Centrifugal fans with two separate inlets and one shared outlet are called double inlet fans. It delivers high-volume outputs that require this kind of fan. Two inlet boxes are either directly welded to the volute casing or flange mounted to the fan intake side to receive the air or gas. Dampers are also used in the design of these inlet boxes to handle the air entering downstream. When the air or gas reaches the impeller, it is housed inside the volute casing and positioned between bearings. Both air streams combine and exit through a single outlet. These fans typically have larger sizes than normal fans, yet they have a good output.
Applications of Double Inlet Centrifugal Fans
Cement industry: Double inlet fans provide air flow rates above 590,000 CFM. Raw mill fans, mill fans, and filter fans are mostly used in the cement industry. A single double inlet fan will handle the entire process in the cement industry. When using two separate fans, the higher power consumption can be decreased.
Power plant industry: In the power plant industry, a double-inlet industrial fan is used to provide a high volume of air gas to keep the coal burning. However, a large-capacity plant requires more supply of air or gas. Double inlet fans deliver a continuous supply of air to the coal, which is required for various processes in the power plant industry.
2. Multi-stage Centrifugal Fans
Some industries will require multi-stage centrifugal fans to get the expected outcomes when there is high-pressure demand. If the impeller blades' diameter of the industrial fan is increased, it will be able to provide pressure as high as 20%. As a result, multistage centrifugal fans are used by many large-scale businesses to meet their high-pressure airflow requirements.
How does it work?
This multi-stage industrial fan is more powerful than the standard one. Two impellers are mounted on a single. Both impellers relate to a tube that helps to pass the air or gas. The process of high-pressure works as follows:
First, the air or gas flows to the first impeller, the air pressure increases, and then it is passed to the second impeller. It picks up more pressure before exiting the system radially. Up to 1.7 bar pressure, multi-stage centrifugal fans provide around 50% more pressure than standard fans.
Applications of Multistage Centrifugal Fans
Chemical Industry: Heavy duty industrial fans are used in the chemical sector to generate high pressures. It is required to evaporate fluid from chemical substances. Other industries, such as cement, power plants, wood & paper, etc. can also use these industrial fans. Application and industry requirements can be taken into account when designing heavy duty industrial fans. Sizes are widely configurable to accommodate a wide range of varied industrial applications. Multi-stages using high-strength materials will be able to withstand corrosive gases, abrasive components, and high temperatures.
Conclusion
Heavy duty industrial fans are widely used for various applications. It has already established its masses in the market. Buy the best centrifugal fans from a reputed brand.
