When power plant operators and boiler manufacturers across India need reliable, heavy-duty, and high-volume air handling solutions for their auxiliary systems, they turn to Shivam Engineering & Fabrication. As a leading axial flow fan manufacturer for power plants and industrial boilers, we have supplied hundreds of units to thermal power plants, captive power plants, and industrial boiler houses across the country. Our axial flow fans are engineered for continuous 24/7 operation in demanding environments – perfectly suited for power generation applications.

Why Power Plants Need Heavy-Duty Axial Flow Fans

Power plants and industrial boilers require high-volume air handling for various auxiliary systems. Our specially designed axial flow fans feature:

• High-Volume Airflow – Capable of handling up to 500,000+ CFM for large cooling towers.
• Heavy-Duty Construction – Robust MS or SS304 construction for continuous operation.
• Corrosion-Resistant Options – FRP or SS304 for cooling tower and coastal applications.
• Weatherproof Design – Suitable for outdoor installation on cooling towers and rooftops.
• Low Noise Options – For power plants located near residential areas.
• Continuous Duty Rating – Designed for 24/7 operation with minimal maintenance.
• Reversible Flow Options – For boiler house ventilation requiring both supply and exhaust.

Key Applications of Axial Flow Fans in Power Plants & Boilers

1. Cooling Tower Ventilation

High-volume axial fans for cooling towers used in thermal power plants. Features include FRP or SS304 construction for corrosion resistance, low noise design, and high-efficiency aerofoil blades.

2. Boiler House Ventilation

Fresh air supply and hot air/fume exhaust from boiler house areas. Reversible axial fans can provide both supply and exhaust functions from a single location.

3. FD Fan Inlet Air (Forced Draft Fan Inlet)

Clean air supply to FD fan inlets, often requiring filtration and weather protection.

4. Condenser Cooling Air

Air-cooled condenser applications requiring high-volume airflow across condenser tubes.

5. Coal Handling Plant (CHP) Ventilation

Ventilation of coal crusher houses, conveyor galleries, and bunker areas to remove coal dust and maintain air quality.

6. General Plant Ventilation

Fresh air supply and exhaust from turbine halls, control rooms, switchgear rooms, and other plant areas.

7. Transformer Cooling Rooms

Ventilation of transformer rooms to remove heat and maintain safe operating temperatures.

Axial Fan Types for Power Plants & Boilers

Material Options for Power Plant Environments

Depending on the application and site conditions, Shivam Engineering & Fabrication offers different construction materials:

• Heavy-Duty Mild Steel (MS) with Epoxy Coating – For boiler house ventilation, CHP ventilation, and general plant ventilation (indoor applications).
• Stainless Steel SS304 – For coastal power plants and corrosive environments.
• Fiber Reinforced Plastic (FRP) – For cooling tower applications requiring maximum corrosion resistance and lightweight construction.
• Cast Aluminum Impellers – Lightweight, corrosion-resistant, high-efficiency aerofoil design – standard for most models.

Cooling Tower Axial Fans

For cooling tower applications, Shivam Engineering & Fabrication offers specialized axial fans with the following features:

• FRP or SS304 Construction – Maximum corrosion resistance in wet, humid cooling tower environments.
• High-Volume Airflow – Capable of handling up to 500,000+ CFM for large natural draft or induced draft cooling towers.
• Low Noise Design – Aerofoil blades and precision balancing for noise-sensitive areas.
• Weatherproof Motors – IP55/IP56 motors suitable for outdoor, wet environments.
• Adjustable Blade Pitch – Allows optimization of airflow for seasonal variations.

Reversible Axial Fans for Boiler House Ventilation

For boiler house applications requiring both fresh air supply and fume exhaust, we offer reversible axial flow fans:

• Same fan can provide supply (push) or exhaust (pull) by reversing motor direction.
• Aerofoil blades designed for efficient airflow in both directions.
• Eliminates need for separate supply and exhaust fans, reducing installation space and cost.
• Ideal for seasonal ventilation requirements – fresh air in winter, hot air exhaust in summer.
