The Influence of Structural Design of FeCrAl metal fiber fiber on Flame Stability

1. Gas and air mixing efficiency

The three-dimensional woven structure of FeCrAl metal fibers has a uniform pore distribution, which can promote sufficient pre mixing of gas and air, reduce the phenomenon of local gas concentration being too high or too low, and thus avoid flame flickering or extinguishing.

The complex network structure of FeCrAl metal fibers generates small turbulence when airflow passes through, accelerating mixing speed and enhancing the stability of combustion reactions.

2. Flame retention capability

The high specific surface area of metal fibers (larger contact area per unit volume) can adsorb more active free radicals, prolong flame residence time, and enhance flame stability.

Metal fiber materials have high thermal conductivity, and during combustion, heat is quickly transferred to the unburned area through the fiber network, forming continuous thermal feedback and maintaining stable flame propagation speed.

3. Anti interference performance: The pore density and directional design of the FeCrAl metal fiber structure can suppress external airflow disturbances (such as wind and pressure fluctuations), prevent flame deviation or deflagration.

Reasonable pore size design (usually at the micrometer level) can reduce carbon deposition and avoid local incomplete combustion or flameout caused by pore blockage.
