OUTSTANDING
ADVANTAGES
HIGH SPECIFIC LOAD, STABLE COMBUSTION
Ceramat Gas Burner has an open porosity of approximately 95%,
making it highly permeable. The gas or gas/air mixture passing
through it can easily permeate the entire surface and burns off in
the form of a flame carpet. The flames remain on the surface and
do not lift off. This offers the advantages of stable combustion,
a wide range of modulation and high specific load, which allow
compact burner design.
WIDE MODULATION RANGE
Ceramat Gas Burner is suitable for use in both blue-flame and
radiant modes and offers a correspondingly wide modulation
range, as well as the possibility of precise, continuous adjustment.
ELECTRICAL CONDUCTIVITY
SiC coating makes Ceramat burner conductive. Electricity can pass
through the material, being this a great advantage for the control of
the flame detection. The ionization signal is very good, similar to a
metal burner.
EVEN RADIATION
Ceramat Gas Burner can also be used as a radiant burner. The
burner surface is resistant up to 1.000 °C and only glows to a
depth of 1 mm, while the temperature on the underside remains
at approximately 150 °C. The material also resists thermal shock.
With its high resistance to heat and changing temperatures, it
can be used under unusually difficult combustion conditions.
LOW HEAT EXPANSION
Since the material practically does not expand when heated, the
shape remains virtually unchanged during operation. This
makes it possible to use simple frame and burner designs and
ensures uniform, stable combustion.
RIGID, SELF-SUPPORTING STRUCTURE
The silicon carbide coating gives rigidity to the fibers. This coating
bonds the fibers together at their interfaces to form a rigid
structure. Thus Ceramat Gas Burner is self-supporting and will
not significantly sag, even on larger burner surfaces and when
exposed to fan pressure. No additional support is required.
LOW EMISSIONS
Extremely thin and
highly resistant to
heat and thermal
shock: from 950
°C to 150 °C in just
3.2 mm.
The simple adaptability of Ceramat Gas Burner to a specific
heating system and its wide radiation range ensure very low CO
and NOx values without reducing the performance and flame
stability of the burner.
Perforated Ceramat
Gas Burner:
the flames stabilize
each other.
FAST REACTION
Ceramat Gas Burner is extremely thin and ultra-light. Its low
thermal mass results in very fast burner responsiveness
during heating and cooling. Upon ignition, a bright
radiation is produced, signaling immediate heat. When the
flame is extinguished, Ceramat Gas Burner cools within
seconds so that its surface can be safely touched. It is ideal for
burners and installations that need to be frequently turned on
and off in short cycles.
LOW THERMAL CONDUCTIVITY
High surface temperatures are not transmitted to lower layers.
When used as a radiant burner, this allows for a temperature
differential of up to 800 ºC between the topside and
the underside. There is no danger of flashback and the
temperature of the burner housing remains very low, even
without additional cooling. This means that even compact
burners can be safely operated with high output.
NO HEALTH HAZARDS
The self-supporting
structure simplifies
frame design and
construction.
At approximately 25 to 30 μm, the diameter of the silicon
carbide coated fibers is much greater than the maximum 3μm
range considered critical for human health conditions. In addition,
the fibers are solidly welded together. If they should break off,
they are heavy enough to fall to the ground instead of being
inhaled, a fact that has been confirmed by independent studies.
Therefore, Ceramat Gas Burner installation and operation does
not generate health hazards.
