Product Specification: Energy Saving Flue Gas Blower (Coupling Driven, Blue)

Product Overview

This high-efficiency flue gas blower is specifically engineered for industrial boilers, incinerators, and thermal processing systems. Its primary function is to safely extract and convey hot, corrosive, or particulate-laden exhaust gases from the combustion chamber to the stack or pollution control equipment.

The unit features a direct-drive via flexible coupling (not a belt drive), ensuring precise alignment, higher power transmission efficiency, and reduced maintenance. The signature Blue Color finish indicates a standard corrosion-resistant coating suitable for indoor or sheltered outdoor industrial environments.

Key Features & Benefits

• Energy Saving Design: The impeller is aerodynamically optimized (typically backward-curved or airfoil blades) to achieve peak efficiency (up to 85%+ static efficiency), significantly reducing power consumption and operational costs compared to standard forward-curve or radial blowers.
• Coupling Driven Reliability: A flexible coupling connects the motor shaft directly to the blower shaft. This eliminates belt slippage, reduces energy loss, requires no belt tensioning, and ensures a longer bearing life.
• Robust Construction: Built to withstand high temperatures and mild corrosion.
  • Housing: Heavy-gauge carbon steel (or optional 304/316L Stainless Steel).
  • Impeller: Cast or fabricated steel, dynamically balanced to ISO 1940 G6.3 grade for vibration-free operation.
  • Shaft: High-strength alloy steel, oversized for deflection resistance.
  • Bearings: Heavy-duty, oversized pillow block bearings designed for high temperature operation, with external grease fittings.
• Thermal Management: Equipped with a shaft-mounted heat slinger (cooling fan) between the bearing housing and the blower casing to dissipate conducted heat from the flue gas.
• Corrosion Protection:
  • Standard Finish: Epoxy-based Blue Color paint (RAL 5010 or similar), providing excellent adhesion and resistance to mild industrial fumes and moisture.
  • Optional: High-temperature silicone paint (for +250°C gases) or specialized acid-resistant coatings.
• Wide Operating Range: Available in multiple sizes (inlet diameters 4" to 80") for flows up to 200,000 CFM and static pressures up to 60" w.g.
