Application
Flameless Venting for Indoor Equipment in Building Materials
Answer in brief
In a cement or lime plant flameless venting belongs to the fuel side.
Coal and alternative fuel mills and their filters often stand inside buildings, and venting them to atmosphere is rarely possible.
- Apply it where the dust is combustible, which is the fuel path.
- Size the vent area with the device efficiency.
- Isolate the fuel path, device or not.

The problem
Fuel preparation equipment stands indoors in many plants, and the dust it handles is combustible while most of the plant's dust is not.
Desired outcome
Indoor fuel equipment protected to its reduced explosion pressure, with the fuel path isolated from the rest of the plant.
Process approach
Flameless devices allow mills, classifiers and filters to be protected in place, with the vent area calculated including the device efficiency.
Alternative fuel dust varies with supply, so the design case uses the worst composition rather than the current one.
Isolation on the fuel path remains necessary, because the device protects only the vessel it sits on.
- Protection applied along the fuel path only.
- Design case based on the worst fuel composition.
- Isolation between fuel equipment.
Selection factors
- Fuel composition range and its explosion characteristics.
- Equipment strength and the vent area required.
- Indoor location and the available alternatives.
- Maintenance access to the device.
- Self-heating behavior in fuel storage.
Common failure modes
- Protection designed for one fuel while the supply changed
- Vent area taken from the bare panel calculation
- Mineral equipment protected unnecessarily while fuel equipment is not
- Device fitted without isolating the fuel path
