This article's table of contents introduction:
- The Issue: Power vs. Air Volume
- Most likely interpretations:
- Standard parameters for a similar Q235 boiler (for reference):
- Conclusion:
It appears you're referencing a specific industrial boiler model: SA Fan Boiler with a power range of 1-2000 kW, made of Q235 carbon steel, with a high air volume of less than 900,000 m³/h.
However, the data as written contains a potential contradiction or misprint.
The Issue: Power vs. Air Volume
- Power: 1–2000 kW (This is a very wide range, covering small residential units up to large industrial units).
- Air Volume: < 900,000 m³/h.
The contradiction: A 2000 kW boiler typically requires an airflow of roughly 3,000 to 4,000 m³/h for combustion. An airflow of 900,000 m³/h is astronomically high for a 2000 kW heat source.
Comparison for scale:
- A 900,000 m³/h fan is comparable to the main ventilation fan in a massive power plant or a large tunnel ventilation system.
- A 2000 kW boiler is roughly the size of a boiler heating a large apartment building or small factory.
Most likely interpretations:
- Typo in the unit:
- The air volume might be 900,000 m³/h for a much larger boiler (e.g., 2000 MW or 20,000 kW), not 2000 kW.
- Or the power is 900 kW with a < 900,000 m³/h fan, which is still extremely high.
- Wrong specification for SA Fan Boiler:
- An "SA Fan Boiler" (sometimes referring to a "Suspension Air" or "Special Air" fan boiler) might be a high-velocity, low-water-content design.
- A 1-2000 kW Q235 boiler with this air volume doesn't match standard combustion calculations.
- Mixture of unrelated data:
- You might be looking at a curves sheet or selection table for a fan used in a boiler draft system, but the heading "SA Fan Boiler" is misleading.
Standard parameters for a similar Q235 boiler (for reference):
- Power: 1,000 kW (approx. 1 ton steam)
- Material: Q235 (mild steel, standard for boiler shells)
- Air volume (combustion fan): ~ 1,100 – 1,300 m³/h
- ID Fan (Induced Draft): ~ 1,500 – 2,000 m³/h (for exhaust)
Conclusion:
You likely have a misprint or mismatch in the specification.
- If 2000 kW is correct, the air volume should be in the range of ~2,500–4,000 m³/h (not 900,000).
- If 900,000 m³/h is correct, the boiler power should be in the MW range (likely > 30,000 kW).
To get a useful answer, please check:
- Is the 900,000 m³/h a model number or a specification?
- Is the unit possibly 900 m³/h (missing decimal)?
- Is this a fresh air fan for a large building using the boiler, not the boiler's combustion fan?
If you can provide the exact model plate or the intended application (heating, process steam, ventilation), I can give you a more accurate assessment.
