High-temperature Fans for Cement Kiln Tail Applications
This critical high-temperature fan is specifically engineered for preheater and calciner systems at the kiln tail of modern dry-process cement production lines. It extracts and conveys high-temperature dust-laden waste gas from C1/C2 cyclones (operating temperature range: 320°C-450°C). The fan establishes system negative pressure, ensures optimal raw meal preheating and calcination, and efficiently directs exhaust gas to subsequent waste heat recovery or gas treatment systems. Its operational performance directly impacts system thermal efficiency, raw meal calcination rate, production line stability, and overall power consumption.
Key Features
- Backward-curved blades for high efficiency and energy savings
- Wear-resistant overlay or lining on blades for extended service life
- Wear-resistant plate lining inside casing for durability
- High-temperature extended support structure design to accommodate thermal expansion effects
