Role of Centrifugal Fans in Industrial Settings

Monday, 13 November 2017 06:15 Written by

Lack of ventilation, machinery producing extra heat, hazardous particulates, fumes & vapors from the processes and several other things can make an industrial setting uncomfortable for workers. As a way to prevent this situation and create ambience in working environment, today many industries are focusing on installing good fan equipment inside their structures. Fans in industrial settings serve several roles, not only in the air cleaning and conditioning, but in other processes like combustion, exhaust systems, conveying, cooling and drying etc. They serve different airflow requirements for different purposes in industries.

Process Fans in Iron and Steel Industry

Monday, 13 November 2017 06:10 Written by

Steel in industries is manufactured in two ways, traditionally by using raw materials like iron ore, coal and limestone in blast furnace or by recycling the material using electric arc furnaces. The first process involves making of molten iron using the raw materials iron ore, coke (pure form of carbon obtained by heating and driving off impurities of coal) and lime in blast furnace. Then it is further followed by combining varying amounts of steel scrap with molten iron in Basic Oxygen Furnace (BOS). The second method requires no raw materials and reuses the existing steel scrap to produce steel in an Electric arc furnace. Both these production processes require several centrifugal fans for drying & heating ore pellets, handling the undersized dust particles, removing and cleaning waste gases, providing combustion air to burn coke, exhausting waste by-products, cooling the product to remove heat etc.

Centrifugal Fans in Industrial De-dusting / Dust Collection

Tuesday, 31 October 2017 07:36 Written by

Industries have unique dust collecting requirements in their production, manufacturing or industrial facilities to reduce pollution, keep the work environment clean and increase safer working conditions for workers. Different industrial processes produce different sized dust particulates, some stay on the ground while others remain suspended in the air. The typical de-dusting mechanism includes a fan system that pushes or pulls the dirty air through filtration process. Based on the type of dust the industrial process produce, different fan equipment is used to accomplish different dust collecting tasks. Centrifugal fans are capable of handling high volume of dust loads, and hence they are widely used in industrial processes for removing dust.

Process Fans in Fertilizer Industry

Fertilizer plants typically require several industrial fans and blowers in its production process. These industrial centrifugal fans should have distinguished capabilities to handle various material types and ensure reliable ventilation. Mainly they should be corrosive resistant because the process includes many chemical materials at different concentrations and mixtures. Most of the modern synthetic fertilizers contain nitrogen, phosphorous, and potassium as primary compounds with secondary nutrients such as calcium, magnesium and sulphur added to them to supply essential nutrients required for plant growth. 

Centrifugal Fans: What’s in a Name?

You would have come across many fans like Pressure Blower, FD fans, ID fans, Raw Mill fans, Flue Gas Recirculation Fans etc. They are all technically centrifugal fans having different names and serving different purpose in the industry. 

Centrifugal Fans Named After their Construction or Design

Centrifugal fans displace air radially, thus diverting the direction of air by 90 degree. At a constant speed of fan, centrifugal fan will move constant volume of air and not constant mass of air. Hence it is called as constant volume fan. This can be achieved from centrifugal fans with different construction and design.

Centrifugal Fans Named After Industrial Process

Depending on the industrial requirements of airflow rate, volume, and pressure centrifugal fans have been customised to serve industry. Centrifugal fans are named as per the function served by them. They are often referred with different names based on the industrial process they support. While the technical functionality of these fans is same, the design element is changed to support several industrial processes.

Centrifugal Fans in Industrial Ventilation

An Industrial building is often a closed building. We want an environment inside the building to be comfortable. There are various types of industrial processes going inside the industrial building. These different processes can make the temperature inside the building higher. This extra heat has to be vented out of the building using an external equipments like fans, louvres, gravity vents, heaters.

Growth in Production Capacity of Manufacturing Industries

Friday, 02 June 2017 11:37 Written by

India is the fastest growing country by GDP. Manufacturing has emerged as one of the high growth sectors in India. As the government of India is emphasizing more on make in India, many manufacturing industries are encouraged to establish in India. India has become one of the most attractive destinations for investments in the manufacturing sector. Many international players have already opened their manufacturing units in India. As India is growing rapidly in manufacturing sector, it has become an attractive hub for foreign investments. Various companies including those engaged in manufacturing of machinery and equipment, electrical and metal products, defense, cement, building and construction material, rubber and plastic products, and automation technology products are expanding.

Multiple Drive Arrangements of a Centrifugal Fan

Wednesday, 31 May 2017 13:28 Written by

When a centrifugal fan is to be installed for any industrial process, the airflow requirement has to be determined before considering different fan arrangements to accomplish the desired performance. Fans typically work better when they have optimal size that fits ideally in the designated area, placed in the right location to withstand the operational conditions and have proper drive method to modulate the speed. When considering different centrifugal fan arrangements, the motor will have various placement settings with respect to the drive side of the fan. The fan can use different drive methods, depending on whether the motor is independent of the fan as in belt drive arrangement or motor connected directly to the fan axle or shaft as in direct drive configuration.
