FECRALLOY Metal fibre, from Fibertech, is applied for surface combustion.
The surface combustion has the fine splited flame on the whole burner surface. It makes the thermal energy uniform over the designated surface for diverse applications.
The orange flame has short flame length usually below 1 mm, the medium heats to incandescence and releases the energy input as thermal radiation while the blue flame has longer flame length around 10 mm above the media surface and releases energy mainly through convection.
The metal fibre burner media is the best solution for the surface combustion, as it has the high resistance against oxidation under high temperature, thermal and mechanical shock.
Features
- Fast homogeneous heating – the heating time can be reduced over 70% compared to that of the conventional burner system.
- High modulation capability – its range is 700 ~ 1,600 ºC, and High TDR (Turn Down Ratio) is available up to 15:1.
- Reduction of combustion chamber size – up to 70% thanks to the short flame length.
- Low CO and NOx emission – it provides performance near 10 ppm with the aid of burner head technologies (The upper emission regulates 50ppm.).
- High thermal efficiency – it provides to superior fuel saving which gives the thermal efficiency increase up to 30%.
Metal fibre solutions
Metal fibre is delivered as metal fibre wool and several kinds of (sintered) mats.
Metal fibre wool
Metal fibre wool can be delivered tailor made in bags, strings or other specific forms.
