- My Strong Recommendation to You
Based on your specifications, here is a technical breakdown and sourcing recommendations for a 380V / IP55 Carbon Steel Industrial Ventilation Fan specifically designed for Garbage Incineration applications.
Crucial Warning: Garbage incineration involves extremely corrosive flue gases (acids from burning plastics, chlorides, sulfides) and high temperatures. While you specified Carbon Steel, this material will fail rapidly in standard incineration environments unless it is specifically protected or used in a specific zone.
The "Carbon Steel vs. Reality" Dilemma
- Standard Carbon Steel: Will rust out in weeks/months due to condensation of acidic gases.
- Acceptable Carbon Steel Use: Only acceptable if the fan is on the Cold Air Intake side (fresh air feeding the burner) or the exhaust is treated with a scrubber first.
- For Exhaust (most common): You almost always require Stainless Steel (SS316L / Duplex 2205) or Carbon Steel with a heavy-duty anti-corrosion coating (e.g., Halar or Rubber Lining).
Assuming you understand the corrosion risk and still require C-Steel (perhaps for a pre-combustion air supply), here is the product specification.
Recommended Fan Design: Centrifugal (Radial) Industrial Fan
For waste incineration, a Centrifugal Fan is mandatory (not axial). It must be a heavy-duty, radial-blade design to handle dust and high static pressure.
Technical Specifications (HPI Fan or equivalent)
| Parameter | Specification | Reason for Choice |
|---|---|---|
| Voltage | 400V / 690V / 380V (3-Phase, 50Hz/60Hz) | Matches industrial grid. |
| Enclosure | IP55 | Protects motor from water jets (washdown) and dust in a dirty plant. |
| Material (Impeller & Casing) | Q235B Carbon Steel (or S235JR) | Only for Air Intake or Clean Treated Gas. |
| Coating (Critical) | Anti-Corrosion Epoxy (minimum 3 coats) or Zinc-Rich Primer | Adds moderate protection. |
| Impeller Type | Radial (Paddle Wheel) or Radial Tip | Self-cleaning; handles dust and sticky fly ash. |
| Bearings | Heavy Duty, Pillow Block with external grease lines | Allows re-lubrication from outside the hot housing. |
| Shaft Seal | Packing Gland or Labyrinth Seal | Prevents gas leakage into the motor/bearings. |
| Temperature | Standard: -20°C to +120°C (Max 280°C with heat slinger) | Carbon steel weakens above 400°C. |
| Standard | ISO 5801 / GB/T 1236-2019 | Ensures proper performance testing. |
Model Examples (Chinese & International OEM Standard)
- 9-19 Series: High pressure, small volume (suitable for air supply).
- 9-26 Series: High pressure, medium volume.
- C4-73 Series: Medium pressure, suitable for corrosion-resistant materials (but usually FRP).
- Y5-47 / Y5-48 Series: Specifically designed for Induced Draft (ID) Fans for boilers/incinerators. These often have wear liners. Check if they offer a carbon steel version.
Key Design Features for Incineration Duty
Since you are working with garbage incineration, you must request these modifications even on a Carbon Steel fan:
- Drain Plug: Bottom of the housing must have a threaded drain plug to remove condensate (acidic water).
- Wear Plate: A replaceable wear plate on the impeller shroud (where dust hits first).
- Vibration Monitoring: The fan base must have mount pads for vibration sensors (critical for safety).
- Shaft Cooling: If the gas is >100°C, the shaft must have a Cooling Fan or Heat Slinger to prevent bearing failure.
- Inlet Box: If duct space is tight, request an inlet box to straighten the airflow.
Recommended Manufacturers (Supply Chain Focus)
Since you specified 380V / Carbon Steel / IP55, these are likely Chinese manufacturers (high value for money) or standard European industrial fan houses.
Option A: Chinese Direct (Best Price)
- Shanghai Xinli Fan Co., Ltd: Good for heavy-duty industrial fans.
- Zibo Yingji Fan Co., Ltd: Specializes in High-Temp and Waste Incineration fans.
- Shandong Huadong Boiler Fan Co., Ltd: Standard Y5-47/48 series.
- Contact Tip: Email them with a title: "RFQ: Y5-47 No. 8D / 380V / IP55 / Carbon Steel / For Incinerator ID Fan"
Option B: European / US Distributors
- Howden / Greenheck: They will require SS316 by default for incineration. C-Steel is only for supply air.
- Soler & Palau (S&P): Industrial line.
Price Estimate & Sizing (Approximate)
| Fan Size (Impeller Diameter) | Motor Power (Approx.) | Max Flow (m³/h) | Max Pressure (Pa) | Price Estimate (USD) - C-Steel |
|---|---|---|---|---|
| No. 6.3C | 11 kW | 8,000 | 3,000 | $1,200 - $1,800 |
| No. 8D | 22 kW | 18,000 | 3,500 | $2,500 - $3,800 |
| No. 10D | 45 kW | 35,000 | 4,000 | $5,000 - $7,500 |
| No. 12.5D | 75 kW | 60,000 | 4,500 | $8,000 - $12,000 |
Note: Prices for Stainless Steel are typically 2.5x - 3x higher.
My Strong Recommendation to You
Do not buy a standard carbon steel fan for garbage incineration exhaust.
If you value the fan lasting more than 6 months, request one of these alternatives:
- FRP (Fiberglass Reinforced Plastic): Excellent for corrosion but limited to 80°C gas temp.
- Stainless Steel SS316L: For temperatures up to 400°C. Mandatory for wet/dry scrubber exhaust.
- Coated Carbon Steel: C-Steel with a Halar (ECTFE) or Rubber Lining. This costs 50% more than standard C-Steel but lasts 5x longer.
Final Answer: Product: Centrifugal Industrial Fan, Model Y5-47/48 (or 9-26), 380V/660V, IP55 Motor, Fabricated Carbon Steel Housing (Q235), Radial Impeller with wear liner, Bottom drain included. Application: Suitable for clean air supply to incinerator combustion air. NOT suitable for corrosive exhaust without coating.
To get a specific quote, I need:
- Airflow (m³/h) and Static Pressure (Pa)
- Gas Temperature (Max & Min)
- Is it Intake or Exhaust? (Critical for material choice)
- Are there scrubbers upstream?
