Axial Flow Type Compressor

The Axial Flow Type Compressor represents a pinnacle of turbomachinery, engineered for the most demanding industrial applications that require immense gas volumes and a medium pressure rise. Operating on principles similar to those of multi-stage axial fans-but with significantly greater complexity, often featuring dozens of stages-this compressor is a technology-intensive capital asset. It primarily handles air, although other gases may also be processed, and it is governed by stringent international standards, including API 672 and ISO 2314, ensuring reliability in mission-critical applications ranging from metallurgy to large-scale chemical processing.

At the heart of the compressor is a multi-stage rotor–stator assembly. Rotating blades incrementally accelerate the gas, while stationary blades convert velocity into pressure and guide the flow into the subsequent stage. Advanced models incorporate fully adjustable stator blades, enabling the Axial Flow Type Compressor to maintain peak efficiency across a broad operating range (70%–105% load) while expanding its stable operating envelope. The high-speed rotor achieves an exceptional dynamic balance grade of ISO 1940 G1.0 or better and is supported by a comprehensive condition monitoring system that tracks vibration, displacement, temperature, and other critical parameters in real time.

A primary application is blast air supply for large-scale blast furnace ironmaking. For furnaces exceeding 4,000 m³, an Axial Flow Type Compressor-driven by a steam turbine or electric motor-delivers thousands of cubic meters of air per minute at pressures exceeding 0.5 MPa. It must operate continuously and reliably for years while seamlessly adapting to production demands. The adjustable stator mechanism provides precise response to load variations, and the API 672-compliant design ensures near-absolute operational reliability, making the compressor a cornerstone of industrial productivity.
