Know Uses of Centrifugal Fans in Industrial Processes

Industrial Fans, Centrifugal Fans or Blower Fans are a cost-effective and efficient way to generate intermittent and continuous airflow for many industrial processes. These industrial fans are efficiently used in various industrial processes like ventilation, aeration, cooling, drying, and conveying materials. Centrifugal fans are mainly designed to operate at low as well as high temperatures, with acidic fumes, corrosive gases, etc. 

Centrifugal Fans are the most common type of industrial fan that ensure proper ventilation for the employees working in the industry. Industries like steel plants, paper, and pulp industry, textile industry, chemical industry, food industry, and glass industry used centrifugal fans to regulate the hot air generated from machinery. 

Ventech Systems is an experienced Centrifugal Fan manufacturer company in India. Below, we have listed some highlighted industrial processes where centrifugal blower fans can be utilized. 

1). Recirculation of Air 

The production of energy and heat is massive in heavy industries. Centrifugal fans provide a consistent and stable airflow that is needed to maintain the fuel combustion properly. 

For instance, in industrial boilers, centrifugal fans allow fresh air to blow into the system. It maintains the oxygen level suitable for ignition. Similarly, in power plant boilers, FD or Forced Draft Fans supply air necessary for fuel combustion. This process pushes the air through the air supply system into the furnace during combustion. 

2). Industrial Cooling 

Centrifugal fans are also termed industrial cooling fans because they can be used to displace gas or air from one place to another. Primarily these fans are used to drive cold air and blow hot air out of industry. 

For instance, in cement manufacturing factories, cooling fans are used in a large number. They used to blow cold air to cool the clinker. Similarly, in glass manufacturing factories, centrifugal fans are required to cool down the high temperature of the oven's walls to cool the manufacturing material. 

However, air exhaust depends on the construction and design of specific fans. Centrifugal fans have a big diameter that helps to produce a high volume of air required in industrial processes. 

3). Re-Dusting: 

In many industries, centrifugal fans are used to collect dust. There are many types of dust collectors required to remove the nuisance. Industrial fans used are either induced draft fans or forced draft fans through the system. 

The re-dusting process in industries requires centrifugal fans that work on the pressure-type system and depression-type system applications. 

4). Air Drying 

Induced Draft Fans or Industrial Forced are required in industrial processes to control the moisture content and temperature. Hot air can be forced through these cooling fans, which also helps to circulate the air to remove excessive moisture.  

For instance, In the paper Industry, these cooling fans are used to dry paper sheets. It occurs by passing the construction material through a heated oven or exhaust air from the pulp of paper. Similarly, in Food Industries, centrifugal fans are required to remove food’s moisture content before it is sent for the packaging. 

5). Conveying Material 

In industries, centrifugal fans are used to convey or handle the manufacturing materials. Light-weight or small materials like sand, sawdust, plastic pallets, and wood chips can be effortlessly handled by Centrifugal Fans. But for heavy materials such as alloys and steel, centrifugal fans are required as abrasion-resistant. 

Common types of centrifugal fans used in industries to convey materials are Industry Exhausters and high-pressure Radial Fans.

Centrifugal Fans: Essential in All Types of Industries

A centrifugal fan is an air-moving pump or motor. It draws air into the blower before pushing it out at a 90-degree angle. A centrifugal fan consists primarily of an impeller and a motor. Impellers pull or suction air as opposed to propellers, which push.

Centrifugal fans are common in the HVAC industry. They are more likely to be found in building ventilation systems. Industrial processes frequently utilize them to transport gases or chemicals. Centrifugal fans are also used in air pollution control systems. They are effective at dust management.

They are employed in industries where higher volumes of airflow with constant pressure are required. They are quite beneficial in industrial processes such as dust collection, drying and cooling, general ventilation, and air circulation.

The most noticeable distinction between centrifugal blowers is the angle of their blades, which might be backward, forward, or radial (the blades extend out from the impeller).

A Centrifugal Fan's Operation

The revolving fan blade creates a low-pressure zone in the center of the blade and a high-pressure zone at the blade's edges. It also increases the kinetic energy of the air. The low-pressure area in the fan's center creates a vacuum, which draws air into the fan. The air flows from the center of the fan to the fan's outside edges. It flows out of the container around the impeller in the correct direction.

These centrifugal fans have their quality features. The sort of industrial fan you require in your operation to achieve efficiency and dependability is determined by airflow volume, static pressure, and the application of the fan. Once you've identified those criteria, you'll be able to tell Ventech Systems to select the best fan for your application.

Choose Efficient Centrifugal Fans in Easy Steps

The complete performance of an electronic industrial fan's design is not limited by constraints of the technology, but it ultimately boils down to the issues of heat dissipation. With efficient superconductors, the operation of all electronic equipment results in the loss of power that is inevitably dissipated. Along with this fact, equipment and designs of centrifugal fans are needed to consider how heat affects the design and performance of the fan. With it, they ensure that the design of the fan continues to operate properly without any damages to individual parts and components. As the system grows with more complexities, rapidly increasing densities, systems.

thermal management is the major design consideration.  

There are many instances in which the heat can be conducted away from the critical components, through the case, circuit board, and dissipated to the surroundings. For the larger system, servers, computers, and similar equipment of the rack-mount, where the conduction and cooling of the natural convection are not sufficient, fans are required to provide forced-air cooling. 

Once a designer concludes, the question arises like, “What kind of industrial fan do I need?” which is followed by “What size and shape does the industrial fan need to be?” With other things in life, especially in the matter of engineering, there is an ideal process to arrive at answers to such questions. Here we are giving you a few simple steps that can help you with the process:

Step 1: Firstly, understand how and where the heat is generated.

Step 2: Determine the airflow of the fan that is needed to keep checking the temperature rise.

Step 3: Choose the right type of industrial fans that are suitable for the requirement of the lower airflow.

Step 4: Final considerations, such as the noise, both electrical and acoustic, and speed control of the fan are the main factors that a designer needs to consider. 

Finally, the motors of the centrifugal fans give rise to electromagnetic interference (EMI). While this feature is inherent with all types of DC fans, that can usually be suppressed using the shielding and ferrite beads.

 

Like it, unwanted heat generated by these fans will always be challenging to designs of electronic fans.  However, the implementation of industrial fans allows electronic systems that operate and optimize to improve design’s longevity.

Factors to Consider in Selection of a Good Centrifugal Fan for Industries

Centrifugal fan blowers functions to move the air from place to place. Centrifugal fans are available in different sizes and types having certain benefits. In recent times, there is a great diversity in applications of centrifugal fans including drying, conveying, cooling, aerating and ventilation, etc. In order to select a fan as per the requirement, there are varied specifications that need to select accordingly. A fan with the right material and design can be chosen by considering your industrial process and its requirement, efficiency, and reliability. The correct process to select a fan type totally depends on different factors such as the type, size, airflow rate, density, the static pressure of the air, temperature range, system resistance, space constraints, variations in operating conditions, material to be handled, etc.

Type and Size of The Fan or Blower

Centrifugal fans come with varied designs and sizes such as radial blade, backward inclined, forward curved, airfoil, etc that depending on the blade of the fan. These industrial fans deliver air with different flow rates and pressures. The right centrifugal fan needed to be selected to fulfill needs. Each centrifugal blower has varied abilities and its own applications to perform the industrial process. Choosing the right size of such fans is important to have a good efficiency of energy and system performance. If you will use an undersized or oversized fan, then it becomes difficult to meet with variable demand and conditions to meet the requirements of an industry.

Airflow Rate & Pressure

The airflow rate can be determined to know how well these fans can handle used material against the resistance of the system. Wrong ducting, improper installation of dampers or, system effects an impact on the airflow negatively. These kinds of issues can be evaluated while choosing the proper fan. If these fans s not maintained with a proper velocity of the air, then they will not carry material through the system to a destination point.

Pressure Drop

All the controlling components are used at the outlet or inlet of the fan system that will affect the airflow. Hence while determining the air pressure and airflow requirements of the fan system, it is required to consider restrictions on the airflow that is caused because of the movement of the air through ducts, filters, hose, pipes, louvers, and dampers with other components to control the air. 

Handling Material

Several factors are required to be considered to handle the material that is going through the industrial fan. Choosing the right fan with the proper blades is important to not accumulate on blades. To clean applications like airfoil blades are efficient to make granular, dirty, radial wheels work appropriately. While handling the wet or moist material, centrifugal fans with special coatings need to be used for housing, which helps to avoid the corrosion and abrasion of the material. In high-temperature applications like shaft coolers, motor heat shields, insulated housings, shaft seals, are needed to be used in the construction of the fan to avoid temperature effects on the fan system.

Space Constraints

To design fan assemblies, it is required to leave sufficient space for ductwork, foundation, maintenance access, and structural support, etc. A good location needs to be chosen by considering desired airflow and structural constraints. If the industrial fan system has to mount on the roof/wall, it is important to determine the weight, speed, and size of the fan. It is essential to choose the most efficient fan having a minimum noise to be fit within the available space in the application.

Instructions for Operation, Repair, and Maintenance Of Centrifugal Fans

Like other machinery used in industries that undergo rigorous use and play an important role, centrifugal blowers and fans also need inspection regularly. Particularly, the surfaces and impellers of these fans tend to collect deposits that reduce the fan’s efficiency and most often result comes in imbalance and vibration.

However, it needs to be kept in mind that only the necessary amount of cleaning minimally should carry out and needs to be done carefully. Any kind of harshness during the cleaning process can damage the flow of air on the surface finish. The kind of process to clean would depend only on the current situation of how rigorously the fan is used.

Inspection of The Fan

During the installation of the centrifugal fan, its news to be inspected every few hours. The inspection frequency gradually can be reduced daily, or week-by-weekly, then monthly.

Visual Inspection

It is important to take a look in detail if you see any sign of damage in the blades of the fan or the structural deterioration. In industries, usually, the fans are run continuously, so the inspections can be made annually. However, if the annual inspection is impossible, then it is important to carry out the maintenance process during short shutdowns.

Cleaning Blades of The Fan

If the fan blades got dirt-coated, the efficiency of the fan would become less. Usually, an effective filter system keeps out the dirt mostly. However, it is important and wise to carry out a minimum of one inspection per year. As the impeller blades moving with the forward curved fans are mostly scoop-shaped, they tend to collect the dirt particularly. Even if the fan is small, then cleaning of blades may require nearly an hour to be taken off.

Inspection of Motor of The Fans

Getting the centrifugal fan unexpectedly low, is one of the most visible signs shown during the motor failure. However, the low efficiency of an amperage also indicates the assembly of the fan needs maintenance. Apart from it, you may also want to check that the motor is working in the right direction or not and make sure that the condenser of the fan is not cycling much rapidly.

Lubricate The Bearings

It is important to lubricate the sleeve bearings twice or thrice per year as they have running surfaces made up of metal. These bearings must be labeled with recommended lubrication intervals and lubricant type. You might be kept in mind that such bearings are not re-greased. In case, if bearing generates excessive noise, heat, and vibration, it seems to fail soon. It usually happens when bearings become old, and then the bearing cassette is required to be replaced.

Belts Adjustment

The centrifugal fan’s belts need to be protected and secured with dripping oil, oil mist, and chemicals. If these belts are not protected and exposed to chemicals and oils, and not adjusting properly, then it means they need replacements more often than usuals. If the belts of the centrifugal fans are too tight, they pressurize shaft bearings and motor the fan excessively. It may cause the bearing or the belt to fail. Lose the belt while wearing out easily and cause these fans to lose the torque slip off.

Note: The supply of the electricity should completely shut off and other lockout procedures should be followed just before beginning the process. To prevent a wheel from rotating, the assembly of the rotation needs to be blocked.

Centrifugal Fans - Their Uses And How They Work

When fans were first invented, they were used to only blow air around to cool the environment.  As our society advanced, however, the use of fans spread to many other areas of human endeavor; automotive, aviation, electronics, etc. 

Now, apart from cooling, they are used for exhaust, combustion, aeration, ventilation, particulate transport, air-purification, and drying. So, depending on the specific requirements (pressure and airflow capabilities), the fans are designed accordingly. 

A good example of an industrial fan is a centrifugal fan, also known as a centrifugal blower. In comparison to axial fans, they are more cost-effective and have a simpler design. They are extensively used in HVAC (heating, ventilation, air-conditioning) and air pollution control systems. 

Mode of function: They are ideally suited for ducted applications since resistance to airflow is higher and airflow needs to be generated at high pressure. Their main role is the rapid escalation of fluids that pass through them. 

Components: They consist of the fan housing, impellers, inlet and outlet ducts, a drive shaft, and a driving mechanism. After the entry of air into the fan housing via the inlet duct, it reaches the center of the impeller. The driving mechanism helps the driving shaft to make the impellers rotate. Rotation of the impellers leads to the creation of kinetic energy, which gives high speed to airflow released from the outlet duct. 

The driving mechanism is the most important part of these fans, as it provides the required force for the impeller blades to rotate. 

Depending on their pressure generation capabilities, they can be classified into three categories: low pressure, medium pressure, and high pressure.

Depending on their blade designs, their classification is as follows.

1. Airflow blade. They are efficient and quiet.
2. Radial blade. They are ideal for dust removal and humidity control systems.
3. Forward curve: They are most suitable for air pollution control, ventilation, and exhaust systems. 
4. Backward curve: They are curved backward and have high efficiency.

How To Choose The Right Centrifugal Fans For Your Plant

The basic function of centrifugal fans is to drive air from one place to another. They have diverse applications: cooling, drying, conveying, ventilation, etc. The Centrifugal fan manufacturers offer different types of fans with different sizes, with each type offering certain benefits. 

So, while purchasing the right centrifugal fans for your industrial setup, you need to choose the ones that are reliable, have the right design and material, fulfill your process requirements, and give optimum efficiency. Your choice will depend on several factors. A few of them are given below.

Fan type and size:

Depending on their fan blade configuration, centrifugal fans have different designs, e.g., backward inclined, radial blade, forward curved, airfoil design. They deliver different airflow rates at different pressures. If you choose an under-sized fan, it may not meet the variable demand conditions of the industrial process in question. If you use over-sized fans to increase efficiency, you may end up with higher capital and operation costs and lower reliability.

Airflow rate:

It determines how well the fan system will handle the material against the system resistance. Wrong ducting and improper installation of dampers, for instance, may have an adverse impact on airflow. It will not carry the material through the system to the destination point if proper velocity is not maintained. 

Static pressure:

Ducts and other system components restrict airflow, so you need to consider the pressure drop through them while selecting the fan. 

The density of the air to be moved:

Air density varies from the standard because of many factors, e.g., altitude, moisture, temperature, presence of other gases. If the fan works in a system where the material in question has a higher or lower density than the standard, you need to correct the standard conditions. So, while choosing the centrifugal fans, you must consider the effect of these factors on the air density. 

We hope you find the above information useful.

Centrifugal Blowers – Features And Applications

 Centrifugal blowers provide directional airflow by maximizing static pressure. They are particularly useful in industrial and commercial environments where it is not easy to supply air at a uniform rate. 

Their applications range from fume exhaust, dust handling, material conveying, induced draft, forced draft, etc. They are used in a wide range of industries such as foundries; power, cement, and chemical plants; engineering industries, etc. 

A blower’s main function is to provide and accommodate a large flow of air to various parts of the building. It does this by rotating several blades connected to a hub and shaft with the help of a motor or turbine. A centrifugal blower uses the centrifugal power generated by the rotation of impellers to increase the kinetic energy of air. The air then moves from the impellers into the fan housing. Since the requirements of every plant are unique, their centrifugal blowers need to be customized accordingly. 

Ventech Systems, who are leading manufacturers of these blowers, offer a wide range to suit the specific needs of every client. Depending on the requirements, the impellers in their blowers are of various types:

• Backward Inclined
• Backward Curved
• Backward Flat Sloping

What Is A Centrifugal Fan? How Is It Better From Ordinary Fan?

 The centrifugal fan was invented in 1832 by the military engineer Lieutenant General Alexander Sablukov of the Imperial Russian Army of the Russian Empire. Centrifugal Fans, often called blowers, are very different from axial fans. The pressure of the incoming air stream is increased by a fan wheel, which is a series of blades mounted on a circular hub. Centrifugal fans move air radially than normal fans. The direction of the outgoing air generally changes 90 ° from the direction of the incoming air. The airflow generated by centrifugal fans passes through a system of ducts or pipes. This will help create a higher pressure airflow from the axial fans. Radial fans produce a smoother airflow than axial fans despite their low flow speed. Centrifugal fans also require higher energy consumption.

Types of centrifugal fan blades:

The Manufacturer Of Centrifugal Fans has designed these fans in four basic types, each with its purpose:

• Radial: Centrifugal fans of high pressure and medium flow. Centrifugal fans are best suited for dusty industrial applications or gaseous or humid environments.
• Forward Curve: For clean air, ventilation, and air intake applications, forward curved medium and high-pressure air fans can be used.
• Backward Curve: They provide High-pressure, high-flow, high-efficiency reversible fan options. Performance decreases as flow increases in the most efficient area of ​​the system.
• Airfoil: This type of fan has an Aerodynamic surface hence they are the most efficient fans for clean air applications.
