Metal fiber Premix burners
Premix burners covered with metal fibre mesh are tried and proven products for premixed combustion.
The fibre covering guarantees efficient thermal protection for the steel base. This prevents thermal deformations and breaking of the burner, thus upping reliability and lifetime of the component and extending its field of use.
Metal fibre is generally employed in large sized, highly performing burners for high modulations, in which the component is subject to greater thermal stress.
For low thermal loads, combustion occurs on the surface and the metal mesh works in radiant mode.
The fibre burners guarantee excellent flame stability across the entire power range, while observing
the strictest European standards of NOx and CO emissions.
POLIDORO employs a three-dimensional metal mesh structure. The material used for the fibre is a high heat resistant alloy, Fe-Cr-Al, in order to guarantee a long lifetime and high resistance to high temperature corrosion.
The metal mesh was developed to meet the following needs:
- correct combustion
- noisiness
- dimensional stability
- no flashback
- flame stability at high λ values
- Output powers ranging from 100 kW/m2 to 2000 kW/m2
- High modulations of up to 1:10
Size
Fibre burners are produced with cylindrical and flat shape.
The flat burners may be rectangular or round.
The minimum and maximum dimensions of the surface area of the flat burners’ flame are 100x100mm and 600x600mm respectively.
The diameters of the cylindrical burners are standard, while lengths may vary within the maximum length indicated.
Diameters and lengths different from those indicated are also taken into consideration.
