Type A And Type D Transmission Modes For High Temperature Centrifugal Fan With Advanced Structural Design High Temperature Centrifugal Fan

The core characteristics of high-temperature centrifugal fans revolve around "adapting to high-temperature working conditions and ensuring stable operation", with key features summarized in 4 points:

1. Strong high-temperature resistance: Core components (impellers, casings) are mostly made of high-temperature-resistant materials such as 310S heat-resistant steel and Cr25Ni20, or coated with high-temperature ceramic coatings. They can withstand long-term erosion and radiant heat from high-temperature gases ranging from 100℃ to 900℃ (some special models can reach 1200℃), preventing component deformation and burnout.

2. Structural resistance to thermal deformation: Thermal expansion and contraction gaps are reserved in the design, and impellers adopt symmetrical or reinforced structures. This reduces vibration and abnormal noise caused by thermal expansion and contraction of materials at high temperatures, ensuring structural stability during long-term operation.

3. Targeted cooling protection: Motors are mostly equipped with independent cooling systems (such as air cooling and water cooling), and some bearing boxes also have cooling devices. These block the conduction of high-temperature gases to motors and bearings, preventing core transmission components from failing due to high temperatures.

4. Adaptation to the characteristics of high-temperature gases: Blade angles and casing flow channels are optimized to cope with the low density and variable viscosity of high-temperature gases. This reduces wind pressure loss, ensures stable air volume and pressure output even under high-temperature working conditions, and meets the needs of boiler induced draft, kiln smoke exhaust, etc.
