SIMEC
Centrifugal fan for a pusher furnace
Kleema sized, designed and manufactured a centrifugal fan for SIMEC’s pusher furnace. SIMEC is a steel producer whose long-steel portfolio includes reinforcing bars for construction.
Kleema scope: fan sizing, design and manufacture.
- Client / industry
- SIMEC · Steelmaking
- Application
- Pusher furnace
- Approximate flow rate
- 120,000 m³/h
- Gas temperature
- Up to 440 °C
The challenge: high flow under demanding conditions
Handling approximately 120,000 m³/h of gases at temperatures up to 440 °C, with entrained particles, required aerodynamic sizing combined with resistance to wear and thermal effects.
Engineering around process conditions
The solution used a backward-curved impeller, abrasion-resistant material at critical points and construction designed for the specified thermal conditions. The design considered temperature and prolonged exposure effects, including creep, and provided for protective thermal insulation.
Engineering solutions
| Backward-curved impeller | Impeller geometry selected as part of fan sizing for the stated flow rate and process conditions. |
|---|---|
| Abrasion resistance | Abrasion-resistant material used at critical points exposed to particle wear. |
| High-temperature construction | Construction and material selection considered gas temperature and its effects on components, including creep. |
| Provision for thermal insulation | Construction provided for the application of thermal insulation for protection. |
