Ceramat Gas Burners activity started in 2006. Backed by proven know-how and dedicated
manufacturing facilities, Orkli focuses on the development and production of highly specialized
Gas Burner Media.
Orkli presents a highly permeable, high-performance burner medium for gasfired
residential and industrial applications. The major innovation in Ceramat
Gas Burner is found in its interior: ceramic fibers are formed into a mat
structure, coated with silicon carbide in a CVD process, and welded at points
of contact. The result: a burner surface with outstanding characteristics.
Orkli burners provide a lot of advantages, not only for Gas Boilers and Heaters,
but also for other applications like Fireplaces, Oil boilers, Industrial processes or
Cooking systems.

CHARACTERISTICS
• High specific load: the combination of
a highly permeable burner material and
perforations supports specific loads of
up to 30 Kw/dm 2 with a perfectly stable
flame for all the limit gases. This makes
it possible to design small, compact
burners and systems.
• Wide modulation range: the
material’s flame stability and
temperature resistance support a
modulation range of 1:30. Star-stop
emissions due to frequent on-off cycles
can be substantially reduced, resulting
in low emissions and easily modulated
water temperature for combination
boilers.
• 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.
• Wide radiation range: this ensures low
NOx emissions at low flame temperatures.
• Stable combustion: with all common
gas types and limit gases, burners ignite
and operate safely with Ceramat Gas
Burner FP.
• Load-bearing, self-supporting mat
with thermal expansion: Ceramat Gas
Burner FP makes it possible to design
simple, cost-efficient burners.
• Variable geometry: for optimal heat
transfer, the flat burner surface can be
fully adapted to the heating system.
• Variable perforation: the perforation
pattern of the burner surface is
customizable and determined as a
function of system requirements.

CERAMAT GAS BURNER FP
FOR INDUSTRIAL FURNACES AND DRYERS
INSTANT REACTIVITY, OPTIMIZED PRODUCTION
Ceramat Gas Burner FN is a highly efficient burner medium made of silicon carbide coated ceramic fibers solidly welded
together to form a self-supporting mat structure. This highly permeable, homogeneous burner mat is ideal for radiant gas
burners in industrial furnaces and drying installations.
CHARACTERISTICS
CHARACTERISTICS
• Realistic flame pattern: Ceramat Gas
Burner FN is extremely porous so that the gas
flows through its entire surface to create lively
flames with changing heights and positions,
just like a real log fire. This effect is also
obtained in closed, room-air independent
systems.
• Glow for an even more natural look:
Ceramat Gas Burner FN not only makes it
possible to bring artificial logs and embers
to a radiant glow, but it can also glow itself.
And since the mat supports temperatures up
to 1.000 °C, the 950 °C glowing temperature
poses absolutely no problem.
• The neutral colour of Ceramat Gas Burner FN
blends perfectly with the logs and fire, unlike
shiny stainless steel, for example.
• Stable combustion: with all common gas
types and limit gases, burners ignite and
operate safely with Ceramat Gas Burner FN.
• Simple, cost- and space-efficient burner
design due to the rigid, self-supporting structure
of the mat and its minimal thermal expansion.
• High flexibility: the mat can be supplied in any
flat shape and size. Thus, Ceramat Gas Burner
FN makes it possible to adapt the output of the
burner to the customer’s individual requirements.
• Modulation potential for variable flames:
even with very low flames, stable combustion
maintains a natural-looking flame pattern.
• Low emission values: properly matched
complete systems meet the strictest exhaust
gas and efficiency standards.
• Instant reaction: full radiation is obtained
within three seconds after ignition. And the
radiation stops when the burner is shut off.
The temperature of Ceramat Gas Burner
FN surface immediately drops to a point
where it can be safely touched. By effectively
preventing residual heat and avoiding long
pre-heating periods, this fast reaction provides
optimal system control.
• Homogeneous mat structure: Ceramat Gas
Burner FN ensures uniform radiation.
• Clean surface combustion: very low NOx
and CO emissions reduce the environmental
impact.
• High efficiency: a properly matched system
with Ceramat Gas Burner FN saves energy
costs, especially when compared to electric
heating systems.
• Wide modulation range: the desired
temperature can be precisely set and is easily
adjustable when required.
• Variable geometry: the burner medium
makes it possible to precisely adapt the
burner surface to the requirements of the
installation.
• Rigid, self-supporting structure: very low
thermal expansion and low pressure drop
simplify burner design.
• High temperature resistance: despite high
specific loads the burner surface has a long
life expectancy.

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.
