Manufacturing of Induced Draft Fan Rotor and Stator

The Manufacturing of Induced Draft Fan Rotor and Stator project was carried out as part of Engineering Services to support the fabrication of a complete ID Fan Rotor and Stator set for a 135 MW unit. The work covered the main manufacturing stages from raw material forming, casting component preparation, static casing manufacture, shaft machining, impeller fabrication and welding, up to final balancing of the ID Fan impeller.

Scope of Work

Taka Turbo handled the entire manufacturing process under strict engineering standards to ensure durability, precision, and long-term operational reliability. The scope of work included:

• Forging Shaft – producing the shaft through hot forging for maximum mechanical strength.
• Casting Hub – precision casting of the hub using high-grade materials for balanced rotation.
• Static Casing Manufacture – welding and fabrication of the fan casing for high-pressure endurance.
• Machining Shaft – precision machining to achieve tight geometric tolerances.
• Impeller Fabrication & Welding – manufacturing and joining of impeller blades using industrial-grade welding techniques.
• Dynamic Balancing – performing high-precision balancing to ensure smooth, vibration-free operation.

Results

• A complete ID Fan Rotor and Stator assembly was successfully manufactured with exceptional precision.
• Mechanical and aerodynamic performance met all operational standards from the client.
• Balancing test achieved minimal vibration and maximum efficiency.
• Project completed on schedule and fully compliant with client specifications.
